What is a chiller

A chiller is a efficient cooling equipment, which removes heat from a liquid via a vapor-compression or absorption refrigeration cycle. There are several types of chiller, including water-cooled chiller, air-cooled chiller according to cooling system. Chiller is widely used in many fields, such as industrial factories, chemical labs, food-making field and many other fields.Chiller is widely used in hotels, restaurants, fast-food restaurants, Karaoke, OK song and dance halls, cafes, supermarket preservation, fisheries, library food processing, medical and health, households and other various consumer places.


What is the working principle of chiller

The working principle of chiller is as follow:

  1. The chilled water pump of the water storage tank continuously circulates through the plate or grid evaporator;
  2. After the compressor is operated, it is suctioned, compressed, exhausted, condensed (liquefied) , throttled, and then the -10 to -18 degrees of low-temperature evaporation endothermic vaporizationhappens. Frozen water condenses into a layer of ice at a lower temperature evaporator surface at a water temperature of 0 degrees.
  3. When the ice layer is condensedto a certain thickness, after the evaporation temperature of the refrigerant reaches a temperature-controlled set temperature, the defrost solenoid valve that is turned on is often de-iced by means of a heat pump.

How does adsorption chiller work

Adsorption chiller is also known as adsorption refrigeration system. Its basic structure is composed of modules such as generator, condenser, liquid reservoir, evaporator, adsorber and valve. In the daytime, the temperature of the collector increases with the increase in air temperature, the pressure in the refrigerant evaporation collector increases, and the gas enters the condenser and condenses to form a liquid. At night, the temperature decreases and the adsorbent absorbs refrigeration. The pressure of the vapor in the evaporator decreases, so more liquid will be vaporized, and the heat will be absorbed during evaporation to cool down.
