Abstract

The present disclosure relates to the field of air conditioning, and specifically provides an air conditioning system and control method for blocking refrigerant leakage, which aims to solve the problem that the existing air conditioning system poses potential risks due to the inability to block refrigerant leakage in time. To this end, the air conditioning system of the present disclosure includes: a liquid-side control valve arranged in communication between a throttling device of the air conditioning system and an evaporator of the air conditioning system; a gas-side control valve arranged in communication between a compressor of the air conditioning system and the evaporator of the air conditioning system; a refrigerant concentration detector arranged on the evaporator and used to detect refrigerant concentration in a space around the evaporator; and a controller selectively controlling working states of the liquid-side control valve and the gas-side control valve according to a detection value of the refrigerant concentration detector. The present disclosure not only can automatically block the leakage of refrigerant, but also the present disclosure can reduce the number of components in the air conditioning system circuit, reduce assembly welding points, and at the same time reduce production costs.
