Air conditioning system and running method thereof

Abstract

The invention discloses an air conditioning system. The air conditioning system comprises a four-way reversing valve and a first compressor, an evaporator and a first condenser which are connected with the four-way reversing valve through pipeline separately; the four-way reversing valve comprises a first valve port and a second valve port, the first valve port is connected with one end of a first-level coiled pipe, a first pipeline and a second pipeline which are leaded out from the second valve port are connected with one end of the first condenser and one end of a reheating coiled pipe of the evaporator in a butt-joint mode respectively, and the other end of the reheating coiled pipe and a pipeline leaded out from the other end of the first condenser are connected to the other end of the first-level coiled pipe in a communicating mode; and a first electronic expansion valve is arranged at the communicating front end of the pipeline communicating with the first condenser and the first-level coiled pipe, a second electronic expansion valve and a first one-way valve are arranged at the communicating front end of the pipeline communicating with the reheating coiled pipe and the first-level coiled pipe, and an electromagnetic valve is arranged on the second pipeline. According to the air conditioning system, the indoor temperature is maintained while dehumidifying is conducted, and the comfortable indoor environment can be achieved.

Description

technical field [0001] The invention relates to the field of air-conditioning equipment, in particular to an air-conditioning system and an operating method thereof. Background technique [0002] In an environment with low temperature and high humidity, such as the rainy season in the middle and lower reaches of the Yangtze River and coastal areas, it is difficult to dry clothes, furniture is damp, and the human body is uncomfortable. Existing air conditioners all have a dehumidification function, and the flow direction of the refrigerant in the refrigeration pipeline is the same in the dehumidification operation mode and the cooling operation mode of the air conditioner, so there is no essential difference between the dehumidification and cooling in the existing air conditioning system However, in the dehumidification mode, the indoor temperature cannot be controlled, and low-temperature air supply will be generated, which will also bring about a decrease in the indoor temp...

Problems solved by technology

Existing air conditioners all have a dehumidification function, and the flow direction of the refrigerant in the refrigeration pipeline is the same in the dehumidification operation mode and the cooling operation mode of the air conditioner, so there is no essential difference between the dehumidification and cooling in the existing air conditioning system , and in the dehumidification operation mode, the indoor temperature cannot be controlled, and low-temperature air supply will be generated, which will also bring about a decrease in the indoor temperature while dehumidifying, causing people in the room to feel cold and unable to obtain a comfortable indoor environment
