The direction of arrow B is the traffic direction of refrigerant in air-supply module 100 introduced, and after the air-supply module 100 starting the embodiment of the present invention, magnetic valve 144 is being in full-gear, and electric expansion valve 143 adjusts aperture, to regulate cold medium flux according to design temperature.Through major cycle restricting element 203 part refrigerant liquid through the first hand-operated valve 141, electric expansion valve 143 enter snakelike bending refrigerant pipeline 132 and by heat conduction to heat-exchanger rig 133, thus gasify with the air heat-exchange cooling medium liquid evacuator body that breeze fan 120 sucks, the cold media gas of gasification returns compression-type refrigeration device through magnetic valve 144, second hand-operated valve 142, again sucked compressor 201, enter and again circulate.After air-supply module 100 quits work, electric expansion valve 143 and magnetic valve 144 Close All, do not affect main kind of refrigeration cycle.
In the above course of work, above First Heat Exchanger 202 is condenser, and the second heat exchanger 204 is evaporimeter, and heat-exchanger rig 133 is also evaporimeter.
Fig. 8 is the another kind of fundamental diagram of heat-exchange system according to an embodiment of the invention, part in Fig. 8 dotted line frame is for being arranged at the compression-type refrigeration heat pump assembly of lampblack absorber 100 outside, compared with the compression-type refrigeration device of Fig. 7, increase and be provided with four-way change-over valve 205 to change the refrigerant flow direction, both, under refrigeration mode can being run on, also heat pump mode can be worked in.
When compression-type refrigeration heat pump assembly is in refrigeration work pattern, the HTHP cold media gas guiding First Heat Exchanger 202 that compressor exports by four-way change-over valve 205, compression-type refrigeration device shown in the motion cycle of refrigerant and Fig. 7 completely the same, still be First Heat Exchanger 202 be condenser, second heat exchanger 204 is evaporimeter, heat-exchanger rig 133 is also evaporimeter, and heat-exchanger rig 133 is for reducing gas flow temperature.
When compression heat pump device is in heat pump mode of operation, the HTHP cold media gas that compressor 201 exports by four-way change-over valve 205 leads the second heat exchanger 204, the high pressure refrigerant vapor that compressor 201 is discharged, the second heat exchanger 204 is flowed into after cross valve 205, the latent heat of releasing during refrigerant vapor condenses, release heat, condensed liquid refrigerant, First Heat Exchanger 202 is entered from flowing counterflow through restricting element 203, absorb external heat and evaporate, steam after evaporation is sucked by compressor 201 after four-way change-over valve 205, completes and heats circulation.
After the air-supply module 100 starting the embodiment of the present invention, magnetic valve 144 is being in full-gear, and electric expansion valve 143 adjusts aperture, to regulate cold medium flux according to design temperature.The refrigerant of the second heat exchanger 204 point is flowed through second-hand and is moved valve 142, enter after magnetic valve 144 snakelike bending refrigerant pipeline 132 and by heat conduction to heat-exchanger rig 133, thus the air heat-exchange cold media gas condensation liquefaction sucked with breeze fan 120, release heat, improve the temperature of the air-supply air-flow of air-supply module 100, return compression heat pump major cycle through electric expansion valve 143, first hand-operated valve 141.
In the process, the second heat exchanger 204 is condenser with heat-exchanger rig 133, and First Heat Exchanger 202 is evaporimeter, and heat-exchanger rig 133 is for improving gas flow temperature.The heat-exchange system of this embodiment both can send cool breeze during the broiling summer, also can blow hot blast in winter to user.
The compression-type refrigeration device of the heat-exchange system of above embodiment and compression heat pump device can according to the electrical appliance arrangement situation choice for uses in kitchen, both can complete the transformation of carrying out of existing electrical equipment, also directly can install in the placement process of whole kitchen, thus utilize the external compression such as air-conditioning, refrigerator formula refrigerating heat pump device as the refrigerant providing source in heat-exchange system, combine with lampblack absorber, be suitable for being arranged in whole kitchen, thus provide better kitchen environment for user.
So far, those skilled in the art will recognize that, although multiple exemplary embodiment of the present invention is illustrate and described herein detailed, but, without departing from the spirit and scope of the present invention, still can directly determine or derive other modification many or amendment of meeting the principle of the invention according to content disclosed by the invention.Therefore, scope of the present invention should be understood and regard as and cover all these other modification or amendments.
