Abstract: A heat pump system includes a main heat pump system, a heat retaining layer and a reflecting layer coated on an partial inner surface of a building, a directly expanded strong cool-heat radiation plate having a distance from the reflecting layer, a heat radiating layer located at a side of the directly expanded strong cool-heat radiation plate and having a distance from the directly expanded strong cool-heat radiation plate, a buffer plate disposed between the heat radiating layer and the directly expanded strong cool-heat radiation plate, an anti-condensation trough disposed below the directly expanded strong cool-heat radiation plate. A sealed cavity is enclosed by the heat radiating layer and a wall surface, and the wall surface is formed by a combination of the partial inner surface of the building, the heat retaining layer and the reflecting layer, and, the sealed cavity is filled with air.

Abstract: A heat pump system, including a main heat pump system and a directly expanded strong cool-heat radiation plate provided on the building surface and serving as the terminal of the main heat pump system. The directly expanded strong cool-heat radiation plate enables refrigerant in the main heat pump system to circulate therein. Since the heat pump system of the present application adopts the directly expanded strong cool-heat radiation plate as the terminal of the main heat pump system, refrigerant in the main heat pump system may exchange heat with air by means of the directly expanded strong cool-heat radiation plate directly, instead of secondary heat exchange of the refrigerant loop and the water circulation loop, thereby reducing loss in intermediate heat exchange, improving the heat exchange efficiency and heat utilization, and omitting the circulating pump for water circulation. An air-conditioner with the heat pump system is further disclosed.
