Cold water machines are divided into two types: air-cooled cold water machines and water-cooled cold water machines in the industry. In terms of temperature control, cold water machines are divided into low-temperature cold water machines and room temperature cold water machines. The normal temperature temperature is generally controlled within 0 degrees-35 degrees.The temperature control of the low -temperature machine is generally about 0 degrees -minus 100 degrees.
Self -made cold water machine
The thermostats that can be bought on the market are controlled by the heater, that is, the control heater is powered off when the temperature reaches the set value.The demand for the cold water machine is the opposite: the temperature is higher than the set value, and the temperature is lower than the set value.Therefore, we need to modify the temperature controller.

Cold water machine brand
There are too many cold -water units. It is best to have front -line brands: York, Hitachi, McLee, Cairi, Don Han Bush, Congley, Terity, Dalin, etc., domestic brands: beauty, Gree, etc.
Cold water principle
The principle of nature is a multifunctional machine that removes the liquid steam through compression or thermal absorption refrigeration cycle.Steam compressed cold water units include four major components of steam compressed refrigeration recycling compressors, evaporators, condenser, and some metering devices to achieve different refrigerants.The absorption cold water machine uses water as a refrigerant, and relies on the water and lithium bromide solution between them to achieve a strong affinity with a strong refrigeration effect.
Cold water machine repair
1. Power failure (no display temperature control device, no display, etc.): 1. Municipal electricity breaks, lack of phase, unstable; 2. Check whether the phase -order protector is burned out; 3. The fuse burns out; method: 1. Check the inspectionWhether the municipal electricity is normal, work again after the city power is normal;. 2. Replace the phase -sequential protector; 3. Replace the fuse
