Description

Air conditioning system and air conditioning equipment Technical Field The present utility model relates to the field of air conditioning technologies, and in particular, to an air conditioning system and an air conditioning apparatus. Background Air conditioning systems typically have both heating and cooling functions. When the heat pump system is in heating operation, the outdoor side heat exchanger is used as an evaporator, the temperature is low, when the temperature of the coil pipe of the outdoor side heat exchanger is lower than the dew point temperature of outdoor air and lower than 0 ℃, water vapor in the air can be condensed on the coil pipe to form frost, and the frost layer can increase the thermal resistance of the outdoor side heat exchanger and the resistance of a fan, so that the heat exchange effect is seriously affected, and therefore, the air conditioning system needs to defrost regularly. The defrosting mode of the existing air conditioner is four-way valve reversing, the system is changed from heating circulation to refrigerating circulation, at the moment, the heat exchanger of the external machine is changed into a condenser, high-temperature gas compressed by the compressor enters the outdoor heat exchanger, the frost layer on the surface of the outdoor heat exchanger is rapidly melted by utilizing the high-temperature high-pressure gas, but at the moment, the indoor heat exchanger is an evaporator, heat can be absorbed from the indoor environment, so that the indoor environment temperature fluctuates, and the comfortableness of the indoor environment is influenced.
