Abstract

The invention provides an outdoor unit with the continuous heating function, an air conditioner system and a control method. The outdoor unit comprises a compressor, a first heat exchanger, a second heat exchanger, a first reversing valve, a second reversing valve and two throttling devices; the first heat exchanger has the first state and the second state, according to the first state, one end ofthe first heat exchanger is connected with an exhaust port of the compressor, and the other end of the first heat exchanger is connected with a first connecting pipe; and according to the second state, one end of the first heat exchanger is connected with an air suction port of the compressor, and the other end of the first heat exchanger is connected with the first connecting pipe. According tothe outdoor unit with the continuous heating function, the air conditioner system and the control method, the two heat exchangers are arranged, when the air conditioner outdoor unit enters in the defrosting process, one part of high-temperature refrigerant can enter an indoor unit, the aim that during outdoor unit defrosting, the indoor unit is not shut down and continuously heat is achieved, theunit heating amount is forcefully ensured, and the air outlet temperature and the comfort of the indoor side are kept.

Description

technical field [0001] The invention relates to the technical field of air treatment equipment, in particular to an outdoor unit with continuous heating function, an air conditioning system and a control method. Background technique [0002] Heating and defrosting of multi-connected air conditioners is a common problem in the air conditioning industry today. During the heating operation of the air conditioner, the outdoor unit frosts to a certain extent, and the unit needs to switch to cooling mode to defrost the outdoor unit. During the defrosting process, the indoor unit turns Because the low-pressure evaporating side cannot continue to heat, the indoor temperature will drop to a certain extent, causing great fluctuations in the indoor ambient temperature. The defrosting process takes a certain amount of time. During a defrosting process, the air conditioner compressor needs to experience the following: Three stages: heating operation→reduce the operating frequency to prep...
