Abstract

The invention discloses a continuous heating air conditioning system. The system comprises a compressor, an oil separator, a four-way valve, an indoor heat exchanger, an outdoor heat exchanger and a gas-liquid separator which are sequentially connected, one end of a hot gas bypass branch is connected with an outlet of the oil separator, the other end of the hot gas bypass branch is connected withan inlet of the outdoor heat exchanger, the hot gas bypass branch is used for introducing part of a refrigerant discharged from the oil separator into the outdoor heat exchanger during defrosting fordefrosting, one end of a defrosting bypass branch is connected with an outlet of the outdoor heat exchanger, the other end of the defrosting bypass branch is connected with an inlet of the gas-liquidseparator, and the defrosting bypass branch is used for introducing the refrigerant flowing out of the outdoor heat exchanger into the gas-liquid separator during defrosting, and then entering the compressor. According to the system, the problem that in the prior art, heating of an indoor unit is not continuous and efficient enough during air conditioner defrosting is solved, and the defrosting effect and efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a continuous heating air conditioning system. Background technique [0002] With the gradual advancement of the country's coal-to-electricity policy, air conditioners are becoming important heating equipment. When the air conditioner is running for heating, the refrigerant in the outdoor heat exchanger evaporates and absorbs heat, which will cause frost to form on the outdoor heat exchanger. If the frost is severe, it will affect the heat exchange effect of the outdoor heat exchanger and further affect the performance of the indoor unit. heat effect. [0003] At present, the traditional defrosting method is to change the phase of the four-way valve of the outdoor unit, the system enters the cooling mode, and the outdoor side turns into a condenser to absorb the heat of the refrigerant and defrost the outdoor heat exchanger. This defrosting method turns the indoor side ...
