小型热电联产系统（CHP）是以燃气轮机（或柴油机）为动力同时发电和供热的系统，还可根据需要带动空调制冷成为热、电、冷联供系统。小热电联产系统具有能源利用效率高、环境污染少。运行比较灵活、能量（包括电能、热能、冷能等）输送费用低能量输送损耗少等优点。因此它在国 Small CHP (CHP) is a system that uses gas turbine (or diesel engine) as power source to generate electricity and heat simultaneously. It can also drive air conditioning and cooling to become hot, electricity and cold supply systems as needed. Small combined heat and power system with high energy efficiency, less environmental pollution. Run more flexible, energy (including electricity, heat, cold energy, etc.) transportation costs low energy transmission loss less advantages. So it is in the country
