Abstract

The invention provides an air conditioner system and an air conditioner having the same. The air conditioner system includes a connected indoor heat exchanger, a four-way valve, a compressor, and an outdoor heat exchanger. and / or, the heat exchange unit is set on the pipeline connecting the outdoor heat exchanger and the four-way valve. When defrosting the outdoor heat exchanger, the refrigerant flows through the four-way valve through the indoor heat exchanger Heater, outdoor heat exchanger, and then return to the compressor through the four-way valve. With this technical solution, the four-way valve will not change direction in the defrosting mode, so that the air conditioner can continuously supply heat to the room. At the same time, the heat exchange part is used to heat the refrigerant in the pipeline, ensuring the air conditioner system It has enough energy for heat exchange, which prevents the compressor from causing liquid hammer due to insufficient heat exchange energy. The technical proposal effectively improves the reliability and practicability of the air conditioner system.

Description

technical field [0001] The present invention relates to the technical field of air-conditioning equipment, in particular to an air-conditioner system and an air-conditioner having the same. Background technique [0002] In the prior art, the defrosting modes of the heat pump air conditioner are mainly two modes of refrigeration cycle defrosting and hot gas defrosting. Among them, the defrosting of the refrigeration cycle is to switch the system from the heating cycle to the refrigeration cycle through the four-way valve, and the hot gas defrosting is to increase the flow rate of the expansion valve under the heating cycle so that the high-temperature refrigerant enters the condenser for defrosting. Neither method can heat the room during the defrosting process, which will cause the temperature of the room to drop and affect the comfort of the room. Especially in the refrigeration cycle defrosting method, the indoor heat exchanger acts as an evaporator during defrosting, whi...
