Abstract: An energy-saving system using electric heat pump to recover flue gas waste heat for district heating uses flue gas waste heat recovery tower to absorb the sensible and latent heat in the high-temperature flue gas by direct contact heat and mass transfer. The circulating water is sprayed from the top and the flue gas flows upwards in the tower. The electric heat pump is indirectly connected with circulating water through the anti-corrosion and high-efficiency water-water plate heat exchanger. The return water of the heat-supply network enters the electric heat pump through the anti-corrosion and high-efficiency water-water plate heat exchanger and exchanges heat indirectly with the high-temperature circulating water. The electric heat pump uses the electric energy of the power plant as the driving power.

Abstract: A radiant air conditioning system for controlling comfortable and healthy indoor environment based on infrared sensing technology is disclosed, which comprises air source heat pump outdoor unit, plate evaporator, circulating water pump, etc. Accurate control of air humidity by installing an indoor dehumidification terminal can reduce the surface temperature of radiant cooling terminal and increase the installed area, which will significantly improve the radiant heat exchange between the terminal surface and the human body surface. Infrared sensor technology, which is adopted to obtain the number of indoor occupants and the required outdoor air flow rate, is integrated with a decoupling control of the indoor humidity and air freshness for the accurate control of outdoor air flow rate, and then the supply outdoor air temperature and humidity are regulated for the accurate control of indoor health level.
