DETAILED DESCRIPTION

Detailed descriptions and technical contents of the present invention are illustrated below in conjunction with the accompany drawings. However, it is to be understood that the descriptions and the accompany drawings disclosed herein are merely illustrative and exemplary and not intended to limit the scope of the present invention.

The present invention provides a hybrid air conditioning apparatus mainly includes a cooling and heating air conditioner, and further includes one other air conditioning device communicating with the cooling and heating air conditioner so as to enhance air quality output therefrom, reduce power consumption, reduce waste in space, make all kinds of air properties (e.g. temperature, moisture and carbon dioxide concentration) provided uniformly. FIGS. 1 to 4 are schematic planar views according to the first to the fourth embodiments of the present invention.

Please refer to FIG. 1, showing a hybrid air conditioning apparatus according to the first embodiment of the present invention. The hybrid air conditioning apparatus includes a first air conditioning device and a second air conditioning device. The first air conditioning device is a cooling and heating air conditioner 1 (alternatively called: air conditioner), and the second air conditioning device is an air purifier 2 (alternatively called: air cleaner).

The air purifier 2 is in communication with the cooling and heating air conditioner 1. In other words, an outlet end 22 of the air purifier 2 communicates with an intake end 11 of the cooling and heating air conditioner 1. As a result, outdoor fresh air is purified by the air purifier 2 first, and then the purified clean air is sent to the cooling and heating air conditioner 1 for cooling and heating air adjustment. To be specific, the outdoor fresh air is introduced into the air purifier 2 from an intake end 21 thereof. After the incoming fresh air is purified, it is sent to the cooling and heating air conditioner 1 via the outlet end 22 of the air purifier 2 and the intake end 11 of the cooling and heating air conditioner 1, so that the purified air from the air purifier 2 is converted to cooled air or heated air, and the cooled air or the heated air is then discharged from an outlet end 12 of the cooling and heating air conditioner 1.

The cooling and heating air conditioner 1 includes a first wind blowing power 15, and the air purifier 2 includes a second wind blowing power 25. The cooling and heating air conditioner 1 and the air purifier 2 communicate with each other in series by means of the intake end 21 and the outlet end 22 of the air purifier 2, and the intake end 11 and the outlet end 12 of the cooling and heating air conditioner 1. The air purifier 2 sends the purified clean air to the cooling and heating air conditioner 1 by the second wind blowing power 25, and besides this, the first wind blowing power 15 of the cooling and heating air conditioner 1 can decrease by means of the second wind blowing power 25. In other words, under the premise of the same lift (i.e. the longest distance which the air can be sent to by the hybrid air conditioning apparatus), since the second wind blowing power 25 imparts a force to the first wind blowing power 15, the first wind blowing power 15 of the first air conditioning device 1 can decrease, or alternatively the second wind blowing power 25 of the air purifier 2 can decrease—it depends on which wind blowing power 15, 25 consumes larger power. That is to say, the wind blowing power consuming larger power is selected to decrease so as to reduce power consumption. The first air conditioning device 1 is a heat exchanger and the purifier of the second air conditioning device 2 is a filter. The filter (the second air conditioning device 2) blocks air flow and therefore causes a flow drag therein higher than a flow drag caused by the heat exchanger (the first air conditioning device 1). Therefore, a wind blowing power 25 is arranged in the second air conditioning device 2 to overcome the higher flow drag caused by the second air conditioning device 2.

By combining the cooling and heating air conditioner 1 and the air purifier 2 into one and communicating them with each other, the present invention further provides the following functions:

1. The air sent to the cooling and heating air conditioner 1 is the clean air passing through and purified by the air purifier 2, and concentration of a substance in the air can be reduced via the air purifier 2. Therefore, the cooling and heating air conditioner 1 can operate in the clean air for a long time, and as a result, a lot of filters of the cooling and heating air conditioner 1 can be saved to lower costs. The substance can be, for example, a total volatile organic compound (TVOC), Formaldehyde, and particulate matters.

2. Furthermore, the cooling and heating air conditioner 1 includes an evaporator 16 and a humidifier 17, wherein the evaporator 16 can adjust temperature and humidity, and the humidifier 17 can adjust humidity. Therefore, the cooling and heating air conditioner 1 can perform second adjustment for the incoming clean air from the air purifier 2 by means of the evaporator 16 or/and the humidifier 17, detailed as follows:

a) The cooling and heating air conditioner 1 can humidify the incoming clean air from the air purifier 2 by means of the evaporator 16 or/and the humidifier 17, so as to increase the humidity of the air finally discharged.

b) The cooling and heating air conditioner 1 can heat the incoming clean air from the air purifier 2 by means of the evaporator 16, thus resulting in an increase in the temperature of the air finally discharged. Certainly, the temperature and the humidity of the air finally discharged can both increase at the same time by the hybrid air conditioning apparatus of the present invention.

3. The cooling and heating air conditioner 1 can make the substance attached by means of moisture on a surface of the evaporator 16, thereby resulting in second air filtering (i.e. second air purification) and lowering the concentration of the substance in the air, consequently further purifying the air sent to the cooling and heating air conditioner 1 to enhance the final discharge air quality.

Please refer to FIG. 2, showing a hybrid air conditioning apparatus according to the second embodiment of the present invention. The second embodiment is similar to the first embodiment with the difference that the second air conditioning device is not the air purifier 2 in the first embodiment, detailed as follows.

The hybrid air conditioning apparatus in the second embodiment of the present invention also includes a first air conditioning device and a second air conditioning device. The first air conditioning device is also a cooling and heating air conditioner 1, and the second air conditioning device is an energy recovery ventilator 3 instead.

The energy recovery ventilator 3 performs extra adjustment in temperature or/and humidity according to operations of the cooling and heating air conditioner 1. Therefore, the energy recovery ventilator 3 can send the air adjusted in the temperature or/and the humidity to the cooling and heating air conditioner 1 for the cooling and heating air adjustment.

The energy recovery ventilator 3 is in communication with the cooling and heating air conditioner 1. That is to say, the intake end 11 of the cooling and heating air conditioner 1 communicates with an outlet end 32 of the energy recovery ventilator 3. Accordingly, the outdoor fresh air can be modulated by the energy recovery ventilator 3 first, and the modulated air is then sent to the cooling and heating air conditioner 1 for the cooling and heating air adjustment. To be specific, the outdoor fresh air is introduced into the energy recovery ventilator 3 from an intake end 31 thereof, and after the incoming fresh air is adjusted in the temperature or/and the humidity by the energy recovery ventilator 3, the air is then sent to the cooling and heating air conditioner 1 via the outlet end 32 of the energy recovery ventilator 3 and the intake end 11 of the cooling and heating air conditioner 1. Thus, the air adjusted in the temperature and the humidity from the energy recovery ventilator 3 is converted into cooled air or heated air to be discharged from the outlet end 12 of the cooling and heating air conditioner 1.

By combining the cooling and heating air conditioner 1 and the energy recovery ventilator 3 into one and communicating them with each other, the present invention further provides the following functions.

1. The energy recovery ventilator 3 introduces in fresh air with a low carbon dioxide content from outdoor, the energy recovery ventilator 3 sends the incoming fresh air to the cooling and heating air conditioner 1, and the cooling and heating air conditioner 1 adjusts the fresh air in the temperature or/and the humidity, so it is efficient and quick to enhance the air quality.

2. Since the energy recovery ventilator 3 can effectively precooling and preheating and send the precooled or preheated air to the first air conditioner 1, the first cooling and heating air conditioner 1 correspondingly performs the cooling and heating air adjustment for the precooled or preheated air. In other words, in all of the above-mentioned modulation methods of the second embodiment, the energy recovery ventilator 3 is employed to effect precooling or preheating of the air to be sent to the cooling and heating air conditioner 1. As a result, good air quality is provided, and besides this, there is a great saving in power consumption when the cooling and heating air conditioner 1 adjusts temperature for the final discharge air.

3. Furthermore, the cooling and heating air conditioner 1 can further include an evaporator 16 and a humidifier 17. The evaporator 16 can adjust the temperature and the humidity, and the humidifier 17 can adjust the humidity. Therefore, the cooling and heating air conditioner 1 can perform extra, second adjustment for the incoming air from the energy recovery ventilator 3 via the evaporator 16 or/and the humidifier 17, detailed as follows.

a) The cooling and heating air conditioner 1 can humidify the incoming air adjusted in the temperature or/and the humidity from the energy recovery ventilator 3 via the evaporator 16 or/and the humidifier 17, thereby causing the extra, second adjustment in the humidity for the final discharge air.

b) The cooling and heating air conditioner 1 can heat the incoming air adjusted in the temperature or/and the humidity from the energy recovery ventilator 3 via the evaporator 16, thereby causing second adjustment in the temperature for the final discharge air. Certainly, the hybrid air conditioning apparatus of the present invention can make second adjustment of the final discharge air in the temperature and the humidity at the same time.

4. The energy recovery ventilator 3 can filter the incoming air, and the cooling and heating air conditioner 1 can make a substance in the air attached by means of moisture formed on a surface of the evaporator 16, thereby causing second filtering of the air (i.e. second air purification) and reducing concentration of the substance in the air, so that the air sent to the cooling and heating air conditioner 1 is further purified, and the final discharge air quality is enhanced.

Please refer to FIG. 3 which shows the hybrid air conditioning apparatus according to the third embodiment of the present invention. The third embodiment is similar to the first embodiment with the difference that the third embodiment further includes a third air conditioning device, detailed as follows.

The hybrid air conditioning apparatus according to the third embodiment of the present invention includes: a first air conditioning device, a second air conditioning device and a third air conditioning device. The first air conditioning device is also a cooling and heating air conditioner 1, the second air conditioning device is an air purifier 2, and the third air conditioning device is an energy recovery ventilator 3.

In the third embodiment, the air purifier 2 communicates between the cooling and heating air conditioner 1 and the energy recovery ventilator 3 to be connected in series with each other. Therefore, the outdoor fresh air is introduced in from an intake end 31 of the energy recovery ventilator 3, the incoming fresh air is adjusted in the temperature or/and the humidity by the energy recovery ventilator 3, and then is sent to the air purifier 2 via the outlet end 32 of the energy recovery ventilator 3 and the intake end 21 of the air purifier 2. The air adjusted in the temperature or/and the humidity sent to the air purifier 2 is purified by the air purifier 2, and then is sent to the cooling and heating air conditioning device 1 via the outlet end 22 of the air purifier 2 and the intake end 11 of the cooling and heating air conditioning device 1, so that the air adjusted in the temperature or/and the humidity and purified is converted into cooled air or heated air to be discharged from the outlet end 12 of the cooling and heating air conditioner 1.

By combining the cooling and heating air conditioner 1, the air purifier 2, and the energy recovery ventilator 3 into one, and making them connected in series with each other, the third embodiment provides all of the functions mentioned in the first embodiment and the second embodiment, and a detailed description of the functions is omitted herein for brevity.

The first air conditioning device is also a cooling and heating air conditioner 1, the second air conditioning device is also an air purifier 2, and the third air conditioning device is also an energy recovery ventilator 3.

In the fourth embodiment, the air purifier 2 and the energy recovery ventilator 3 are connected in parallel and each are in communication with the cooling and heating air conditioner 1. Therefore, among the intake end 11 and the outlet end 12 of the cooling and heating air conditioner 1, and the intake end 21 and the outlet end 22 of the air purifier 2, the connection configuration is the same and achieves the same functions as the first embodiment, so a detailed description in this regard is omitted herein for brevity. Moreover, among the intake end 11 and the outlet end 12 of the cooling and heating air conditioner 1, and the intake end 31 and the outlet end 32 of the energy recovery ventilator 3, the connection configuration is the same and achieves the same functions as the second embodiment, so a detailed description in this regard is omitted therein for brevity.

The first air conditioning device 1 is arranged at top of the stack, the third air conditioning device 3 is arranged at bottom of the stack, and the second air conditioning device 2 is stacked between the first air conditioning device 1 and the third air conditioning device 3. The outlet end 22 of the second air conditioning device 2 is directly connected with the intake end 11 of the first air conditioning device 1, and the second air conditioning device 2 is thereby communicated to the first air conditioning device 1.

A supply switching valve 321 is arranged at the outlet end 32 of the third air conditioning device 3, the supply switching valve 321 is respectively connected to indoor and the intake end 11 of the first air conditioning device 1, the supply switching valve 321 could be switched to communicate to indoor (according to FIG. 2) or the intake end 11 of the first air conditioning device 1 (according to FIG. 8), and outdoor air inlet through the intake end 31 of the third air conditioning device 3 could be thereby supplied into indoor (according to FIG. 7) or the first air conditioning device 1 (according to FIG. 8) through the supply switching valve 321. Namely, the outdoor air could be directly supplied into indoor or supplied into indoor via the first air conditioning device 1 for further cooling or heating.

The third air conditioning device 3 includes an intake blower 301 and an exhausting blower 302. The intake blower 301 drives outdoor air to flow into the third air conditioning device 3 through the intake end 31 and flow out the third air conditioning device 3 through the outlet end 32. The exhausting blower 302 drives indoor air to flow into the third air conditioning device 3 through the exhaust switching valve 331, and flow out the third air conditioning device 3 through the exhaust port 332.

An intake prefilter 341, a recycling prefilter 342 and a heat exchanging module 300 are arranged in the third air conditioning device 3 and arranged as a prismatic. A heat exchanging channel 351 is enclosed among the intake prefilter 341, the recycling prefilter 342 and the heat exchanging module 300; an intake channel 352 is enclosed in the third air conditioning device 3 by the intake prefilter 341; a recycling channel 353 is enclosed in the third air conditioning device 3 by the recycling prefilter 342; and an exhausting channel 354 is enclosed in the third air conditioning device 3 by the heat exchanging module 300.
