Our hotel needs to install central air conditioning. What air conditioner is better?

1, depending on the location of the hotel. If the temperature is below 8 degrees below zero in winter and there is no central heating, the thermal effect of using air-cooled mechanism is not good, so it is very expensive to add auxiliary electric heating.

2. If you install a cold and hot split machine in Jiangnan, the one-time investment is small and the use cost is relatively low. Especially when the hotel occupancy rate is lower than 50%, the split machine is the most economical, and the energy efficiency ratio of the frequency conversion split machine is not lower than that of VRV and other air-cooled central air conditioners, but the one-time investment is much lower than that of VRV central air conditioners.

3. In the north of the Yangtze River, if there is a basement room, a cooling tower can be installed on the roof, and a small modular water-cooled chiller using a scroll compressor can be installed to save daily use costs. The COP value of air-cooled mechanical refrigeration is basically less than 3. Don't trust those air-cooled machines with an energy efficiency ratio of 6. Look at the energy efficiency ratio of water-cooled screw machine of Daikin advanced full liquid evaporator of 5.3.

4. The energy efficiency ratio of the water cooling module with scroll compressor can reach above 4.5, saving more than 30% electricity than that of the air cooler. However, if the water-cooled chiller does not use the ground source heat pump unit, it will not be able to heat in winter and will burn the boiler in winter, so it is necessary to install a small fully automatic gas boiler. This configuration has good cooling effect in summer, saves electricity than air cooler, and has good heating effect in winter. The cost of winter is the same as that of heating with an air cooler. When the ambient temperature is below-10℃, the cost of boiler combustion is less than that of air-cooled heating.
