Abstract

The invention provides an air-conditioner system and an air-conditioner with the same. The air-conditioner system comprises an indoor heat exchanger, a four-way valve, a compressor and an outdoor heatexchanger which are communicated; the air-conditioner system further comprises a heat exchange part, the heat exchange part is arranged on a pipe for communicating the outdoor heat exchanger with theindoor heat exchanger, and / or the heat exchange part is arranged on a pipe for communicating the outdoor heat exchanger with the four-way valve; and when defrosting is carried out on the outdoor heatexchanger, a refrigerant sequentially flows through the indoor heat exchanger and the outdoor heat exchanger through the four-way valve and then flows back to the compressor through the four-way valve. By means of the technical scheme, in the defrosting mode, the four-way valve cannot reverse, and therefore the air-conditioner can continuously supply heat to an indoor place, meanwhile, the refrigerant in the pipe is heated through the heat exchange part, it is guaranteed that the air-conditioner system has sufficient energy for heat exchange, and the condition of liquid hammering, caused by insufficient heat exchange energy, of the compressor is prevented. By means of the technical scheme, the reliability and the practicability of the air-conditioner system are improved.

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...
