Abstract

The invention relates to the technical field of air conditioning, in particular to a refrigeration control method of an air conditioner and a condenser. The invention aims at solving the problem thatthe supercooling degree of an existing air conditioner cannot be adjusted. In order to achieve the purpose, the following technical scheme is adopted: the control method comprises the following steps:determining the target supercooling degree of the air conditioner based on the outdoor environment temperature; calculating the actual supercooling degree of the air conditioner; comparing the actualsupercooling degree with the target supercooling degree; and selectively adjusting the opening and closing of a plurality of supercooling valves based on the comparison result, so that the effectivelength of a supercooling pipe section is adjusted. According to the control method, the supercooling degree of the air conditioner can be adjusted, and then the refrigeration energy efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a refrigeration control method and a condenser of an air conditioner. Background technique [0002] When the air conditioner is running, a certain degree of subcooling will be set at the outlet of the condenser to avoid flashing of the liquid refrigerant in the condenser and affect the cooling effect. [0003] In existing air conditioners, subcooling during condensation is usually achieved by setting a subcooling section at the end of the condenser coil. However, during the cooling process of the air conditioner, different outdoor ambient temperatures will lead to different requirements for the subcooling degree of the outdoor condenser by the air conditioning system. However, due to the fixed pipeline of the existing condenser, the subcooling degree cannot be adjusted once it leaves the factory. Therefore, the existing air conditioner cannot improve the operating energ...
