Heat pump air conditioner provided with thermal storage defrosting humidification device based on existing defrosting water

Abstract

The invention provides a heat pump air conditioner provided with a thermal storage defrosting humidification device based on existing defrosting water. The air conditioner comprises an air conditioning device and is characterized in that the air conditioner further comprises the thermal storage defrosting humidification device, the thermal storage defrosting humidification device is arranged belowan outdoor heat exchanger of the air conditioning device, a water collecting port of the thermal storage defrosting humidification device is located below the outdoor heat exchanger, a water outlet of the thermal storage defrosting humidification device is located on the side surface of the outdoor heat exchanger, one end of the thermal storage defrosting humidification device communicates with acapillary tube of the air conditioning device, and the other end of the thermal storage defrosting humidification device communicates with an indoor heat exchanger of the air conditioning device. According to the heat pump air conditioner, defrosting water is utilized for storing excessive heat of a unit during heat supply in winter, during defrosting, the high-temperature defrosting water is sprayed to a frost layer for defrosting firstly and then used as the low-temperature heat source of the unit so as to evaporate retained defrosting water to dryness or to perform deicing, and meanwhile,excessive defrosting water can also be used for indoor humidification; and during refrigerating in summer, generated condensate water is used for indoor humidification or used as part of the cold source. According to the heat pump air conditioner, the defrosting time is short, no indoor heat is sucked away, a humidification function is also achieved, and wasting caused by discharging of the largeamount of defrosting water and condensate water is avoided.

Description

technical field [0001] The invention relates to the field of heat pump air conditioners, in particular to a heat pump air conditioner with a heat storage, defrosting and humidifying device based on self-defrosting water. Background technique [0002] When the air conditioner is heating in winter, the outdoor heat exchanger will often be frosted, especially when it is operating in a high-humidity area. As the amount of frosting increases, the heating capacity of the unit will drop significantly, and the comfort of the room will also decrease, so regular defrosting is required. At present, the widely used reverse cycle defrosting technology has to absorb heat from the room during defrosting, causing the room temperature to drop sharply (about 5-8°C), which seriously affects the comfort of the room, and the operation of the unit is very unstable during defrosting. Poor reliability affects the service life of the unit. [0003] Most of the air conditioners currently on the mar...

Problems solved by technology

[0005] When the air conditioner is cooling in summer, due to the high outdoor air temperature, the condensing temperature will be too high, the input power of the compressor will increase, and the cooling efficiency will decrease. Especially in some places where the outdoor unit is exposed to direct sunlight, the temperature will be higher and the efficiency of the unit will Lower, even the compressor overheating protection shut down

As for the indoor unit, due to the decrease of the indoor air temperature, condensed water will be precipitated, and a large amount of condensed water will be discharged to the outside, which will cause a waste of energy.
