Air circulating system of integrated heat pump

Abstract

The invention discloses an air circulating system of an integrated heat pump, which comprises an air inlet flue, an air outlet flue, a radiating fan and a heat pump computer controller, wherein the air inlet flue is provided with an indoor air inlet and an outdoor air inlet, and an air inlet flue reversing mechanism is arranged in the air inlet flue; and the air outlet flue is provided with an indoor air outlet and an outdoor air outlet, an air outlet flue reversing mechanism is arranged in the air outlet flue, a lower port of the air inlet flue is connected with a heat exchange cavity of the heat pump, and a lower port of the air outlet flue is connected with an exhaust cavity. The heat pump computer controller controls the operation of the air inlet flue reversing mechanism, the air outlet flue reversing mechanism and the radiating fan which also can be manually revered. An air purification device is arranged in a joint of the lower port of the air inlet flue and the heat exchange cavity of the heat pump. The air circulating system of the integrated heat pump can realize the functions of ventilation, air purification and auxiliary cooling, and also can improve the utilization efficiency of heat pump energy.

Description

technical field [0001] The invention relates to an integrated heat pump, in particular to an air circulation system of the integrated heat pump. Background technique [0002] "Heat pump" is a device that can obtain low-grade heat energy from air, water or soil in nature, and provide high-grade heat energy that can be used by people through electricity. When the heat pump is working, it consumes a part of the energy itself, excavates the energy stored in the environmental medium, and uses it by increasing the temperature through the heat transfer working medium circulation system, and the work consumed by the entire heat pump device is only a small part of the output work. , Therefore, the use of heat pump technology can save a lot of high-grade energy. Its working principle is the same as that of the air conditioner, and they all work according to the principle of "reverse Carnot cycle". [0003] At present, most known air source heat pumps adopt a split structure, and a f...

AI Technical Summary

Problems solved by technology

The air source heat pump with split structure is composed of indoor unit and outdoor unit. The air circulation system and evaporator of the heat pump are installed in the outdoor unit. When the heat pump is working, the outdoor air is used to take away the cooling capacity during evaporation. The condensing fan of the heat pump directly blows the air cooled by the evaporator to the outside, and the air circulation system of the heat pump cannot perform air purification and auxiliary cooling

[0004] In the known air source heat pump with an integrated structure, the condensing fan all uses a high-power AC fan. This kind of fan has a lot of noise and blows out a high wind pressure, which is not conducive to human health. This kind of fan is not suitable for ventilation and replacement of the room. gas

Therefore, it is impossible to purify the air, and the evaporator cannot be used to cool the air.
