Investigation and analysis on energy consumption of multi-split air conditioning system in a hotel

Compares and analyses the measured energy consumption of a four-star hotel A with a multi-split air conditioning system and another four-star hotel B with a central air conditioning system. Simulates the energy consumption of the hotel A under two air conditioning system schemes of multi-split air conditioning system and central cold and heat source air conditioning system. Considers that the occupancy rate of hotel rooms changes in real time and the air conditioning system operates under part load most of the time. The use of multi-split air conditioning system has energy saving effect. As the price gradually reduces, the multi-split air conditioning system has certain advantages in hotel application.
