The invention discloses a control method of an air conditioning system. The air conditioning system comprises a compressor, a four-way valve, an outdoor heat exchanger, a first throttling element and an indoor heat exchanger and further comprises a second throttling element, a heat storage device, a first control valve, a second control valve, a third control valve and a fourth control valve. The control method includes the steps that when refrigerating and heating operation is started, the first control valve is controlled to be opened, and the second control valve, the third control valve and the fourth control valve are controlled to be closed; in the refrigerating and heating operation process, the temperature of the heat storage device is detected, and the first control valve, the second control valve, the third control valve and the fourth control valve are controlled to be opened and closed according to the detected temperature of the heat storage device. By the adoption of the control method of the air conditioning system, when the heat storage device is normally refrigerated and heated, no deterioration or excessive evaporation is generated when the temperature is within the reasonable range, and the reliability of the functions of the air conditioning system is guaranteed.
Description
technical field [0001] The invention relates to the field of air conditioning, in particular to a control method for an air conditioning system. Background technique [0002] When the heat pump air conditioner is running at low temperature for heating, a frost layer will form on the surface of the outdoor heat exchanger. In order not to affect the heating effect, the current defrosting method is to switch the mode to cooling mode. Radiation cooling leads to large fluctuations in indoor temperature and affects comfort. [0003] In order to solve this problem, the current measure adopted in the industry is to install a heat storage device around the outdoor unit compressor, and use the heat storage device to accumulate waste heat from the compressor for defrosting. Although this method can achieve a certain amount of heat input in the room during the defrosting process, the stored heat is also better utilized. However, during cooling or heating operation, the thermal storage...
