Precautions For Solar Dc Freezer

  The operation of the Solar DC Freezer system is through three interconnected systems: refrigerant circulation system, water circulation system, and electrical automatic control system.

  The liquid refrigerant in the evaporator absorbs the heat in the water and starts to evaporate. Eventually, a certain temperature difference is formed between the refrigerant and the water. The liquid refrigerant also completely evaporates into a gaseous state, which is then sucked and compressed by the compressor (pressure and temperature increase) ), the gaseous refrigerant absorbs heat through the condenser (air-cooled/water-cooled) and condenses into a liquid. After throttling through an expansion valve (or capillary tube), it becomes a low-temperature and low-pressure refrigerant and enters the evaporator to complete the refrigerant cycle process.

  The air-cooled chiller uses a shell and tube evaporator to exchange heat between water and refrigerant. The refrigerant system absorbs the heat load from the water and cools the water to produce cold water. The heat is brought to the finned condenser through the action of the compressor. Then it is lost to the outside air by the cooling fan (wind cooling); the water-cooled chiller uses a shell and tube evaporator to exchange heat between water and refrigerant. The function of the compressor brings the heat to the shell and tube condenser, and the refrigerant exchanges heat with the water so that the water absorbs the heat and then the heat is taken out of the external cooling tower through the water pipe to be lost (water cooling).
