- a heat collector circuit containing a compressor that compresses and outputs from an output portion thermal media and is capable of varying its own capacity by conversion of its operative frequencies; a condenser forming part of said heat collector circuit, connected to said output portion of said compressor; and a plurality of heat collector units integrally built as housing materials, an input end of which being connected to an output end of said condenser through an expansion valve and an output end of said heat collector connected to said compressor, wherein each heat collector unit contains a plurality of thermal media tubes allowing thermal media to pass therethrough and heat collector fins connected to said thermal media tubes for transferring heat;
- a hot-water pool for storing hot water for use inside said system;
- a fluid heating circuit inclusive of a fluid heater held in a heat-exchange relationship with said condenser outside of said hot-water pool;
- first and second temperature detectors respectively set at inlet and outlet ends of said fluid heater and a third temperature detector sensing fluid temperature of said hot-water pool; and
- a control circuit that controls the capacity of said compressor based on signals from said first, second, and third temperature detectors, said control circuit detecting the fluid temperature of said hot-water pool at the start of the heat-collecting operation based on signals from said third temperature detector, and computing the desired heating capacity based on the difference between said detected fluid temperature of said hot-water pool and a designated temperature to be reached, in reference to the heat-collecting operation time from the start of the operation up to the desired time at which said designated temperature is reached, and based on said temperatures detected by said first and second temperature detectors, and outputing a capacity control signal to said compressor so that said actual heating capacity matches said desired heating capacity.
- 3. Solar heat collector system comprising:
- a heat collector circuit inclusive of a compressor that compresses and outputs thermal media, capable of having its heating capacity varied by conversion of its operative frequencies; a condenser connected to an output side of said compressor; a plurality of heat collector units integrally built as housing materials, an input end of which being connected to an output end of said condenser through an expansion valve and an output end of said heat collector connected to said compressor, wherein each heat collector unit contains a plurality of thermal media tubes allowing thermal media to pass therethrough and heat collector fins connected to said thermal media tubes for transferring heat;
- a hot-water pool storing hot water for use inside said system;
- a fluid heating circuit inclusive of a fluid heater that is held in a heat-exchange relationship with said condenser of said heat collector circuit outside of said hot-water pool;
- first and second temperature detectors set to respective inlet and outlet ends of said fluid heater, and at least one third temperature detector provided for sensing temperature of said hot-water pool; and
- a control circuit for determining the desired heating capacity of said compressor in reference to a detected temperature of said hot-water pool based on signals from said at least one third temperature detector and a difference between said detected temperature and a predetermined temperature to be reached, computing said heating capacity of said compressor further with reference to a temperature difference between said first and second temperature detectors, outputting a capacity control signal to said compressor so that the actual heating capacity can match the desired heating capacity.
- 4. The solar heat collector system as in claim 3 further including:
- an expansion valve provided with a motor driver;
- separate temperature detectors respectively set to respective inlet and outlet ends of said plurality of heat collector units; and
- a control circuit for said expansion valve for controlling an open rate of said expansion valve in reference to signals from said separate temperature detectors set to said respective inlet and outlet ends of said heat collector units, while computing differences in temperature at said inlet and outlet ends of said heat collector units sensed by said separate temperature detectors, before outputting a decompression control signal to said motor driver of said expansion valve, so that said detected temperature differences will match a predetermined value of said differential temperatures.
