Air conditioner system and control method thereof

Abstract

The invention provides an air conditioner system. The air conditioner system comprises a compressor, an outdoor heat exchanger, a first throttling device, a heat storage device, indoor units, a control device, a first connection pipeline, a second connection pipeline and a third connection pipeline, wherein the first connection pipeline is connected between the first throttling device and the heat storage device, and the second connection pipeline is connected between the heat storage device and the control device. The air conditioner system comprises a first operation mode and a second operation mode under switching of the control device; under the first operation mode, the control device controls an exhaust outlet of the compressor to communicate with the second connection pipeline and the third connection pipeline; and under the second operation mode, the control device controls the exhaust outlet of the compressor to communicate with the first connection pipeline and the third connection pipeline. The invention further provides a control method of the air conditioner system. According to the air conditioner system and the control method thereof, continuous heating in the defrosting process can be ensured, moreover the air conditioner system and the control method thereof are suitable for continuous heating of a multiple-on-line air conditioner unit, and the universality of the air conditioner system is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning system for continuous heating and a control method thereof. Background technique [0002] When the outdoor ambient temperature is low and the ambient humidity is high, the heat exchanger of the outdoor unit of the air conditioner will often experience frost, which will seriously affect the heating capacity of the air conditioner unit. Generally, the defrosting of the outdoor heat exchanger is realized by means of system reversing operation. However, this defrosting method prevents the air conditioning unit from continuously heating, and after defrosting, the heating effect of the air conditioning unit is poor. Although some air conditioners with continuous heating can directly divide the exhaust of the compressor by using a switching device, so that the refrigerant discharged from the compressor is divided into two paths, and the two paths of refriger...

Problems solved by technology

[0002] When the outdoor ambient temperature is low and the ambient humidity is high, frost will often appear on the heat exchanger of the outdoor unit of the air conditioner, which will seriously affect the heating capacity of the air conditioner unit

Generally, the defrosting of the outdoor heat exchanger is realized by means of system reversing operation. However, this defrosting method prevents the air conditioning unit from continuously heating, and after the defrosting is completed, the heating effect of the air conditioning unit is poor.

Although some air conditioners with continuous heating can directly divert the exhaust of the compressor by using a switching device, so that the refrigerant discharged from the compressor is divided into two paths, and the two paths of refrigerant are used for heating and defrosting respectively. However, the above continuous The air-conditioning system for heating is not suitable for multi-connected situations, and its versatility is poor
