There is a phenomenon that a friend who uses chiller equipment occasionally encounters is that the chiller cannot control the temperature during cooling or heating. For the mentioned temperature, the temperature cannot be controlled, which means that the temperature is suddenly high or low or reached Below the set temperature, it has been rising (cooling), or it has not been able to reach the required temperature (heating). The second case is mainly explained here, and there are three main reasons for this:
First, the possible reason is that there is a problem with the thermostat.
Second, the most intuitive reason is that the chiller selection is too small to meet the load required by the owner's equipment;
3. If the problem occurs after the machine is used for a while, it may be
A. The chiller heat exchanger is too dirty, it is recommended to clean the heat exchanger (finned heat exchanger or shell and tube heat exchanger);
B. Freon leaks in the chiller system. It is recommended to find the leak points, repair welding and add refrigerant;
C. It is possible that the ambient temperature used by the chiller is relatively harsh, too high or too low, which causes the chiller to fail to meet the requirements. In this case, only a larger chiller can be used to meet the requirements.
By examining the chiller equipment through the above three aspects, you can find the root cause, and find the problem can solve some minor faults, and if the problem is more serious, you should find the manufacturer for repair!
