Abstract

The invention discloses a control method of an electronic expansion valve, a radiation air conditioner and a storage medium. After a startup instruction is received, operation mode information in thestartup instruction is obtained; when the operation mode is refrigeration or dehumidification, the openness of the electronic expansion valve is set as preset initial openness; finally, after the radiation air conditioner is operated by a first preset time length according to the preset initial openness, a superheat degree of an evaporator is calculated, and the openness of the electronic expansion valve is adjusted according to the superheat degree, so that liquid impact and damage of the compressor caused by halfway evaporation of a refrigerant in the evaporator are prevented, frequent stopof the compressor caused by higher superheat degree of the evaporator is prevented, the control precision of the superheat degree of the radiation air conditioner is improved, and the operation stability and the life of the compressor are guaranteed.

Description

technical field [0001] The invention relates to the technical field of radiation air conditioning, in particular to a control method of an electronic expansion valve, a radiation air conditioner, and a storage medium. Background technique [0002] Traditional household air-conditioning indoor units usually use tube-fin heat exchangers, which force air supply through fan design and enhance convection heat exchange to obtain higher heat exchange efficiency. However, this type of air conditioner is noisy and uneven air supply during operation. Moreover, the air supply temperature is low during cooling, and the air supply is dry during heating, which results in low comfort for the human body. [0003] At present, there is a radiant air-conditioning system on the market, which adopts the method of radiation heat exchange + convective heat exchange, and exchanges heat with the enclosure structure through the embedded pipe or capillary network, and then directly radiates the coolin...
