Heat pump system and air-conditioner

A heat pump system, comprising:

• a main heat pump system;
• a heat retaining layer coated on an partial inner surface of a building;
• a reflecting layer coated on the heat retaining layer;
• a directly expanded strong cool-heat radiation plate having a distance from the reflecting layer, wherein an interior of the directly expanded strong cool-heat radiation plate is communicated with the main heat pump system such that refrigerant is circulated in the directly expanded strong cool-heat radiation plate and the main heat pump system;
• a heat radiating layer located at a side, towards an interior of a room, of the directly expanded strong cool-heat radiation plate and having a distance from the directly expanded strong cool-heat radiation plate;
• a supporting rod for supporting the heat radiating layer;
• a first bracket for supporting 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, wherein the buffer plate is configured to weaken the transferring cool or heat quantity from the directly expanded strong cool-heat radiation plate to the room;
• a second bracket for supporting the buffer plate;
• an anti-condensation trough disposed below the directly expanded strong cool-heat radiation plate, wherein the anti-condensation trough includes a condensation discharging pipe extending out of the room;
• wherein 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.
