Air-conditioning system and control method thereof

Abstract

The invention provides an air-conditioning system and a control method thereof. The air-conditioning system comprises a compressor (1), a first heat exchanger (2), an indoor unit heat exchanger (3), a first four-way valve (5) and an energy storage device (6), wherein a first connecting end (51) of the first four-way valve (5) is connected to an exhaust port of the compressor (1), a second connecting end (52) of the first four-way valve (5) is connected to the energy storage device (6), a third connecting end (53) of the first four-way valve (5) is connected to a suction port of the compressor (1), and a fourth connecting end (54) of the first four-way valve (5) is connected to the first heat exchanger (2). The air-conditioning system further comprises a second four-way valve (4), wherein a first connecting end (41) of the second four-way valve (4) is connected to the suction port of the compressor (1), a second connecting end (42) of the second four-way valve (4) is connected to the second heat exchanger (3), a third connecting end (43) of the second four-way valve (4) is connected to the exhaust port of the compressor (1), and a fourth connecting end (44) of the second four-way valve (4) is connected to the first heat exchanger (2). By the adoption of the air-conditioning system and the control method thereof, the technical problem that the power load of the air-conditioning system is large can be solved.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to an air conditioning system and a control method thereof. Background technique [0002] As a mature technology, energy storage is widely used in large-scale central air-conditioning systems, but energy storage technology is rarely used in small household central air-conditioning systems. In recent years, small household central air conditioners have maintained rapid growth, and their operating characteristics will put more and more pressure on the power supply system; and the air conditioning system has more defrosting times during winter operation, and cannot provide support during the defrosting period. Due to the continuous heating of the room, the operating heat load is larger and the energy consumption of the unit is larger in summer operation. [0003] Because the domestic multi-connected air-conditioning system in the prior art has technical problems s...
