The refrigeration principle of calorex refrigerator is that the compressor compresses the lower-pressure steam into higher-pressure steam, so that the volume of the steam is reduced and the pressure is increased. The compressor sucks in the lower-pressure work from the evaporator. The high-quality vapor is sent to the condenser after the pressure is increased, where it is condensed into a higher-pressure liquid. After being throttled by the throttle valve, it becomes a lower-pressure liquid and then sent to the evaporator. The middle absorption heat evaporates and becomes a lower pressure steam, which is then sent to the inlet of the compressor to complete the refrigeration cycle.
High heat exchange efficiency and compact structure: The heat exchange tube adopts high-efficiency internally threaded tubes, and the heat transfer coefficient is more than twice that of traditional shell and tube heat exchangers.
The inlet and outlet of the refrigerant are cleverly sealed to avoid water leakage: the seal is made of high temperature resistant materials, which can withstand 200*C high temperature and -20C low temperature.
Filling with heat insulation material to reduce heat leakage: Fill the foam material between the steel shell and the engineering plastic shell. Effectively reduce the heat leakage of the heat exchanger:, the user does not need to carry out additional insulation around the shell.
Corrosion resistance, long life, not easy to be blocked on the water side: Engineering plastics are more resistant to various corrosions and have a longer lifespan than metals. The water side volume of the heat exchanger is more than twice that of the plate heat exchanger, and it is more resistant to dirt and clogging.
Independent joint is more durable: the nozzle is made of metal material, which is firm and durable.
It can be used under special water quality: it can effectively resist different degrees of acid and alkali, chloride ion corrosion and scouring of sediment.
