How to cool the hotel central air conditioner?

Hotel central air conditioning refrigeration process generally includes the following steps:

1. compressor operation: the compressor of the central air conditioner will suck in low-temperature and low-pressure refrigerant and then compress it into high-temperature and high-pressure gas.

2. Condenser heat dissipation: High temperature and high pressure gas will pass through the condenser, releasing heat and becoming high pressure liquid.

3. Expansion valve throttling: the high-pressure liquid is throttled by the expansion valve to become a low-pressure liquid, and the temperature will also decrease.

4. Evaporator absorbs heat: Low-pressure liquid absorbs indoor heat through evaporator and becomes low-temperature and low-pressure gas.

5. The compressor works again: the low-temperature and low-pressure gas is compressed into high-temperature and high-pressure gas again, and the cycle is repeated.

Through this cycle, the central air conditioner can absorb indoor heat and discharge it outside, thus achieving the effect of refrigeration.
