Basic principles for the design selection of water chillers:
When selecting a chiller unit, the following basic principles should be followed:
1) Priority should be given to the use of electric-driven vapor compression water chillers.
2) When the power supply in the project area is tight and there is gas supply, or excess or waste heat available, direct-fired or steam (hot water) type lithium bromide absorption chiller (heater) units can be used for heating and cooling.
3) Large buildings with multiple energy sources can adopt combined energy systems for cooling and heating.
4) For small and medium-sized buildings in regions with hot summers and cold winters, as well as in arid and water-scarce areas, air source heat pumps or underground buried tube ground source heat pump cold (hot) water units can be used for cooling and heating.
5) When natural water and other resources are available, water source heat pump chiller (heater) units can be used for cooling and heating.
6) In regions where there is a significant difference between peak and off-peak electricity prices, utilizing the off-peak electricity pricing period for cold storage can yield significant economic benefits. Consideration can be given to adopting an electric cold storage system for cooling.
