The present embodiment provides an air-conditioning box device for an automobile, i.e., an air-conditioning box for a heat pump, which includes therein a blower 2, an indoor heat exchanger 3, a PTC heater 4, mode dampers (defrost 5, blow surface 6, blow foot 7), an internal and external circulation damper (not shown), and an air-conditioning box casing 1 forming the device.
The fan 2 may be a blower or other fan, and the fan 2 is used to feed air outside the vehicle into the vehicle or to circulate air inside the vehicle. The fan 2 module can be combined with the air conditioning box 1 and placed in a vehicle, and can also be separated from the air conditioning box 1 and placed in a cabin.
The indoor heat exchanger 3 is used for heating and cooling.
In the direct heat pump system (both the direct heat pump system and its operation principle are prior art, and are not described herein in detail): when heating, the heat pump circulating system directly sends the high-temperature and high-pressure refrigerant compressed by the compressor into the indoor heat exchanger 3, and the indoor heat exchanger 3 exchanges heat with air in the vehicle to realize heating. During refrigeration, the heat pump circulating system sends the refrigerant compressed by the compressor into the outdoor heat exchanger for cooling, then the refrigerant is throttled by the expansion valve and sent into the indoor heat exchanger 3, and the throttled refrigerant is evaporated in the indoor heat exchanger 3 and exchanges heat with air in the vehicle to realize refrigeration.
In an indirect heat pump system (both the indirect heat pump system and its working principle are prior art, and are not described herein): the heat pump circulating system sends cold water or hot water (water or other media) into the indoor heat exchanger 3 through the intermediate heat exchanger, and exchanges heat with air in the vehicle to realize refrigeration or heating.
The PTC heater 4 is used to reheat the air under refrigeration conditions. When needing to refrigerate in the car, the system is according to the operation of refrigeration mode, and air in the car is through the refrigeration of indoor heat exchanger 3 back, if directly blow to the passenger, can arouse the passenger uncomfortable because the temperature is too low sometimes, consequently, need pass through PTC heater 4 with the air and heat, promote the travelling comfort. The air outlet temperature can be adjusted by adjusting the power of the PTC heater 4, or the difference of the left air outlet temperature and the right air outlet temperature of the air conditioning box can be realized by adjusting the power of the two sides of the PTC heater 4. The PTC heater 4 may be a low-pressure PTC heater or a high-pressure PTC heater.
The PTC heater 4 is used for reheating air under the refrigeration and dehumidification working conditions. When the interior of the vehicle needs to be refrigerated and dehumidified, the system operates in a refrigeration mode, and air in the vehicle is refrigerated and dehumidified by the indoor heat exchanger 3 and then heated by the PTC heater 4, so that the air temperature is increased, the humidity is reduced, and the comfort is improved.
The PTC heater 4 can also be used for auxiliary heating in heating conditions.
In summary, the air-conditioning box of the utility model only needs one heat exchanger to participate in the circulation of the refrigeration and heating system, and has simple structure; the temperature air door structure in the prior art is eliminated, the change of the outlet air temperature is realized by adjusting the power of the PTC heater, and air mixing through the temperature air door is not needed; meanwhile, the PTC heaters which can be dispersedly arranged in different areas can realize independent work in multiple areas, different heating powers can be provided according to different requirements, and the functions of different air outlet temperatures of the left position and the right position of the air conditioning box can be realized.
The above is only a preferred embodiment of the present invention, and not intended to limit the scope of the invention, and it should be appreciated by those skilled in the art that various equivalent substitutions and obvious changes made in the specification and drawings should be included within the scope of the present invention.
