Air conditioning system and control method thereof

Abstract

The invention discloses an air conditioning system and a control method of the air conditioning system. The air conditioning system comprises a compressor, a first reversing piece, a second reversing piece, a third reversing piece and a fourth reversing piece, a second pipe orifice of the second reversing piece is connected with the exhaust port, and a third pipe orifice is connected with the air return port; the first end of the outdoor heat exchanger is connected with the second connector, the third end of the indoor heat exchanger is connected with the third connector, and the fourth end of the indoor heat exchanger is connected with the second throttling element which is connected with the first throttling element. The fifth end of the energy storage device is connected with the first pipe opening, the sixth end of the energy storage device is connected with the third throttling element, the third throttling element is connected with the first throttling element, the energy storage device is filled with phase-change materials, and the phase-change temperature of the phase-change materials ranges from 10 DEG C to 25 DEG C. According to the air conditioning system, cold storage and heat storage under the refrigerating and heating working conditions can be achieved through the same energy storage device, in this way, the air conditioning system can store energy in the valley electricity period in the refrigerating and heating seasons and then release energy in the peak electricity period, and the electric load of the system is reduced.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an air conditioning system and a control method for the air conditioning system. Background technique [0002] Due to the single power consumption habit of the power consumer and the further increase of the total power consumption, there is a huge peak-to-valley difference in the load rate of the power grid at this stage, which has caused a large amount of loss in the power transmission process of the power grid. As an important part of power consumption, the energy storage peak regulation of building air conditioning system is of great significance to reduce the peak-valley load difference of the power grid. The multi-split system is an intensive, high-efficiency central air-conditioning system that can meet the cooling and heating needs of users at the same time. After adding the corresponding energy storage module, the system can realize the energy storage and pea...

Problems solved by technology

However, due to the consideration of cooling and heating conditions at the same time, two phase-change energy storage modules for cold storage and heat storage should be added to the system at the same time, which increases the system cost and increases the complexity of the system, which is not conducive to the promotion and industrialization of building energy storage. application
