The air conditioner of the present invention includes: an indoor unit having an indoor heat exchanger for evaporating or condensing the refrigerant by exchanging heat with indoor air; and an outdoor unit having a compression unit for sucking and compressing the refrigerant from the refrigerant suction flow path. After that, it is discharged to the refrigerant discharge channel, and the capacity is variable; the water-refrigerant heat exchanger makes the refrigerant and the heat source water perform heat exchange to condense or evaporate; the outdoor expansion mechanism is installed on the indoor heat exchanger and the water-refrigerant heat exchange Between the heat source water flow path, connected with the water-refrigerant heat exchanger, the pump, arranged on the heat source water flow path, and the flow variable valve, arranged on the heat source water flow path, the opening of the flow variable valve can be adjusted; in refrigeration The opening of the variable flow valve can be changed according to the pressure of the refrigerant discharge flow path during operation, and the opening of the variable flow valve can be changed according to the pressure of the refrigerant suction flow path during heating operation. It can make the circulation of the refrigerant run in an optimal way and improve the reliability of the outdoor unit.
Description
technical field [0001] The present invention relates to an air conditioner and its operating method, in particular to an air conditioner with a water-refrigerant heat exchanger for exchanging heat between refrigerant and water and a water flow path connected to the water-refrigerant heat exchanger and its operating method. Background technique [0002] Generally, an air conditioner is a device that uses the refrigeration cycle of the refrigerant to cool or heat the room. The refrigerant is compressed, condensed, expanded, and evaporated in sequence, and the refrigerant absorbs the surrounding heat when it vaporizes and releases the heat when it is liquefied. , to play the role of cooling or heating. [0003] The air conditioner can use outdoor air to condense or evaporate the refrigerant, and can use heat source water such as water to condense or evaporate the refrigerant. [0004] In an air conditioner, a water-refrigerant heat exchanger for exchanging heat between heat so...
