Abstract

The invention discloses a control method for an air conditioner circulation device. The air conditioner circulation device further comprises a first control valve, a second throttling element, a heat storing device, a third throttling element and a second control valve. The first control valve is arranged between a four-way valve and an air sucking opening of a compressor, and a heat storing heat exchanger of the heat storing device is connected with the first control valve in parallel after being connected with the second throttling element in series. The control method includes the following steps that firstly, when refrigerating and heating operation is started, the first control valve is controlled to be opened, and the second control valve is controlled to be closed; secondly, in the refrigerating and heating operation process, the temperature of the heat storing device is detected, and the first control valve is controlled to be closed and opened according to the detected temperature of the heat storing device. According to the control method for the air conditioner circulation device, the temperature of the heat storing device can be within the reasonable range in the normal refrigerating and heating state, and therefore deterioration and transition evaporation of a heat storing material are avoided, and the function reliability of the heat storing material is ensured.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a control method of an air conditioning cycle device. 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 st...
