Cooling, Heating and Power Engineering
Heat Pump Engineering
Common heat pumps in engineering can be divided into: water source heat pumps (sewage source heat pumps), ground source heat pumps, air source heat pumps and absorption heat pumps (Class I, Class II), etc.
Scope of application: Water source heat pump and ground source heat pump can be widely used in centralized heating and refrigeration systems in hotels, office buildings, schools, shopping malls, villas and residential areas. Air source heat pumps are generally used in small heating and cooling systems, especially in single buildings. Absorption heat pumps are mainly used in various industrial waste heat recovery and heating fields, as well as thermal power plants and other places.

Combined Cooling Heating and Power

Combined Cooling Heating and Power(CCHP) : refers to the distributed energy supply system that uses natural gas clean energy as fuel and applies energy conversion equipment including various thermal power generator sets and waste heat utilization units such as gas turbines, gas internal combustion engines, and micro-combustion engines to provide users with various load requirements of cold, heat and electricity.
Advantages of CCHP
Energy Demand-side Management
Using natural gas and residual heat, the power generation and energy supply system is built near the user's energy management system, which greatly reduces the power loss of transmission.
Supply of Multiple Energy Types
According to the needs of users, electricity, heating, cooling, steam and domestic hot water can be supplied at the same time.
Cascade Utilization of Energy
Improve the comprehensive benefit of energy, and the utilization rate of heat energy can reach 70%-90%.
