What kind of central air conditioning is good in the hotel?

This has a lot to do with the location, orientation and budget of the hotel:

1, 4-star and 5-star are all water system air conditioners, which are more comfortable. The latter two types, including air-cooled modular machines, centrifuges and screw machines, generally need to be equipped with (electric, gas) boilers to solve the heating problem. The cost of air-cooled modular machine is the cheapest, and the average domestic brand is about 200 yuan/㎡ according to the construction area;

2. At present, popular high-end hotel chains (such as Four Seasons, Orange, Mo Lifeng, Vienna, He Yi and Shang Yi) generally use fluorine system (multi-line or air duct machine), so the profit of suppliers is relatively high; There is a system solution of air-cooled modular machine+waste heat recovery machine+air source hot water unit in southern China. Taking room 100 as an example, the biggest advantage of this system is that it uses 20 tons of hot water for free in summer, while in areas like Changsha, it basically uses hot water for five months a year, which can save about 30 thousand electricity bills. However, the disadvantage is that the initial investment is a little more, and the general domestic brands invest about 40 thousand more.

3. Most hotels (the room price is below 200) use air duct machines, because the cost is cheap, domestic brands generally cost 4-5,000 yuan/room;

At present, there are low-temperature air source heat pump units for heating in the north. There are many areas with -25℃ weather, and the electricity price is not subsidized by the government, so the operating cost may be high. If there is no natural gas area, it is a good choice. Finally, it is recommended to use (water) floor heating pipes, which can store heat and have high comfort.

I hope my answer is useful to you!
