Problems solved by technology

As we all know, most of the sanitary hot water in hotels is provided by oil-fired boilers, natural gas boilers, electric boilers or coal boilers. These boilers are not only low in efficiency, but also cause serious pollution, which is contrary to the current advocacy of creating an energy-saving and environmentally friendly society.

Abstract

A heat pump system for preparing hot water using residual-heat comprises three air resources heat pumps, a water resources heat pump, a pump and a water tank. The inlets of the water tank are separately connected with the outlets of the air resources heat pumps and the outlet of the water resources heat pump. The outlets of the water tank are separately connected with the inlets of the air resources heat pumps and the inlet of the water resources heat pump through the pump. When used, the air resources heat pumps are separately arranged in order in the laundry, the boiler room and the switchhouse. The water resources heat pump is pipe-connected with the water-storage pool to prepare hot water using residual-heat.

Description

technical field [0001] The invention relates to a heat supply system, in particular to a heat pump technology for preparing hot water by using equipment waste heat and basement waste heat. Background technique [0002] With the development of the economy and society, numerous hotels and restaurants have sprung up. As we all know, most of the sanitary hot water in hotels is provided by oil-fired boilers, natural gas boilers, electric boilers or coal boilers. These boilers are not only low in efficiency, but also cause serious pollution, which is contrary to the current advocacy of creating an energy-saving and environmentally friendly society. In fact, there is a lot of waste heat and waste heat in the laundry room, boiler room, power distribution room, underground living pool and basement of the hotel. We can use various advanced technologies in our hands to absorb these waste heat and waste heat to make sanitary hot water. If so, it can not only prepare daily necessary sa...
