Laboratory instruments may be required for a chiller. Especially when conducting temperature-sensitive experiments or tests, it is very necessary to use water chillers for refrigeration in order to maintain the stability and accuracy of the experimental environment.

Chiller refrigeration is mainly, mechanical refrigeration, through compression, condensation, throttling, evaporation four processes of closed cycle to achieve refrigeration, is now the most widely used refrigeration cycle.

Compressor: Compress the refrigerant and compress it to the condensation pressure and then drain to the condenser.

Condenser: The high-pressure gas refrigerant from the compressor is condensed into a liquid. During the condensation process, the heat released by the refrigerant vapor is taken away by the cooling water or air.

Throttle valve: Cooling and pressure down, control the refrigerant flow size, make it lead to the evaporator heat evaporation.

Evaporator: The refrigerant liquid after the evaporator evaporation into gas, while absorbing the heat of the cooled object, the cooled object can be liquid refrigerant or air.

In terms of design, the chiller needs to consider the following main factors:

1. Refrigeration efficiency: Select an efficient refrigeration method to ensure that the temperature of the laboratory / instruments in the laboratory is quickly reduced.

2. Stability: Ensure that the chiller maintains stable cooling effect in long time operation to avoid excessive temperature fluctuations.

3. Safety: Considering the equipment and personnel in the laboratory, ensure that the design of the chiller meets the safety standards.

4. Convenient maintenance: the chiller design is simple, easy to maintain and maintain, reduce the maintenance cost and time of users.
