Chiller, in the industry is divided into air-cooled chiller and water-cooled chiller, chiller in temperature control is divided into low-temperature chiller and room temperature chiller, room temperature temperature is generally controlled in the range of 0-35 degrees. Low temperature machine temperature control is generally in the range of 0 degrees - 45 degrees below zero.
A certain amount of water is injected into the water tank of the machine in advance, and the water is cooled by the cold water mechanism and the cooling water is fed into the equipment that needs cooling by the water pump. The chilled water of the machine takes away the heat, and then the temperature rises and returns to the water tank to achieve the cooling effect.
Cold water machine the refrigerant cycle system of liquid refrigerant in the evaporator absorbs the heat in the water and began to evaporate, formed certain temperature difference between refrigerant and water, liquid refrigerant also completely evaporate into a gas compressor suction and after compression, gaseous refrigerant through the condenser heat, condensed into liquid, through the thermal expansion valve throttle into low temperature low pressure refrigerant entering the evaporator, after completing the process of refrigerant cycle.
Advantage
The dl-400 is designed for small LABS and occupies a small space to save lab space. It can be placed directly on a bench or on the floor. It is widely used in chemical, biological and physical experiments at low temperatures.
1) compact design, small and light, small floor space
2) air-cooled design
3) large LCD screen, key operation
