Cooling Hot Water Supplying Water Source Heat Pumps

Water to Water Heat Pump System with heating and cooling: Close loop or open loop geothermal heating and cooling system with heat recovery for hot sanitary water; the terminal is floor heating or Fan Coil heating and cooling. Ground / Water Source Heat Pump System can adopt water of lake, river, and underground and ground heat source; With compressor and electrical power, it can transmit heat from water into the room in winter, and from room into water in summer to achieve the purpose of Commercial Air Conditioner. Heat from the ground is absorbed at low temperatures into a fluid inside a loop of pipe (a ground loop) buried underground. The fluid then passes through a compressor that raises it to a higher temperature, which can then heat water for the heating and hot water circuits of the house. The cooled ground loop fluid passes back into the ground where it absorbs further energy from the ground in a continuous process as long as heating is required.
