介绍了一种新型的高效节能中央空调冷暖系统－- 自备发电、余热利用及热泵冷暖系统。该系统充分发挥了大型建筑必备设备－-自备电源应急柴油发电机的作用，使一次能源在使用中更加符合热力学的原理；该系统不追求某一种机组的高COP，而是利用各种设备的优点，有机匹配，以求一年中最高效的节能。通过与三种常规冷暖系统的一次能源利用率比较，得出该新型冷暖系统的一次能源利用率比三种常规冷暖系统的一次能源利用率高27.88%~104.6%以上。并通过实例计算了采用该系统的某大型广场的全年经济效益。
Introduced a new type of energy efficient central air-conditioning heating and cooling system - self-power generation, waste heat utilization and heat pump heating and cooling system. The system gives full play to the necessary equipment for large-scale construction - self-powered emergency diesel generator to make primary energy more in line with the principles of thermodynamics; the system does not pursue a high COP of a unit, but the use of each The advantages of equipment, organic matching, in order to achieve the most efficient energy-saving year. Compared with the primary energy efficiency of the three conventional heating and cooling systems, the primary energy efficiency of the new heating and cooling system is 27.88% -104.6% higher than that of the three conventional heating and cooling systems. The annual economic benefits of a large square with this system are also calculated by an example.
