The exemplary embodiments generally relate to dehumidifiers, more particularly, compact dehumidifiers.
Conventional dehumidifiers include a housing having a fan to create an air flow, a catch basin within the housing and, means for cooling the flow of air to condense the moisture in the air flow for collection of moisture in the catch basin. Dehumidifiers are frequently used in residential, commercial, or industrial applications to reduce the level of humidity in the air, for example, for health reasons or comfort reasons. Humid air can cause unwanted mold or mildew to grow inside, for example, homes or workplaces or can simply be uncomfortable at extremely warm temperature. Dehumidifiers are also frequently used in, for example, restoration projects to dry an area affected by water damage, such as being flooded, as the drier air helps in the restoration of buildings or other structures. Some of these conventional dehumidifiers are rather complex which lack, among others, simplicity and efficiency.
It would, therefore, be desirable to provide a relatively compact dehumidifier that is reliable and efficient in removing moisture from the air and providing increased air quality compared to conventional dehumidifiers.
The foregoing aspects and other features of the disclosed embodiment are explained in the following description, taken in connection with the accompanying drawings, wherein:

Generally, a refrigerant such as R410A enters the compressor 109 and is compressed increasing its pressure and thus its temperature. The refrigerant is then pumped into the condenser unit 105 via a long tube called the condenser coil 105C. As the hot refrigerant flows through the condenser unit 105, it is cooled by cold air flowing over the condenser coils 105C (heating the air). The refrigerant then runs into the evaporator unit 104 via an evaporator coil 104C, where it is suddenly depressurized, causing it to become very cold. As the unconditioned evaporator air 198e passes through the evaporator unit 104, the air is cooled below its dew point. The water in the unconditioned evaporator air 198e condenses on the cold surface of the evaporator coils. The water, under the effect of gravity is pulled down towards the condensation collection tray 106 positioned beneath the evaporator unit 104. Due to the low pressure/suction region reducing the static pressure of the condensation collection tray 106 the drainage of the water is increased because of low pressure collection channel 115 increasing the diameter of drainage flow pulling the water down and out of the drain 120. The cold dry air continues through and passes over the hot coils of the condenser unit 105 which heats up the unconditioned evaporator air 198e. The unconditioned evaporator air 198e and the bypass air 198b are mixed to form the dehumidified air 199 which is returned to the area it was drawn from.
