LTWH(R) Series 7-250KW Ground Source Heat Pump for Air Conditioning and Hot Water

Geothermal Heat Pump heating and Cooling SYSTEM: 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 air conditioning. 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.

Normally the loop is laid flat or coiled in trenches about two metres deep, but if there is not enough space in your garden you can install a vertical loop down into the ground to a depth of up to 100 metres for a typical domestic home.

Ground Source Heat Pump Advantages:

Environmental-friendly:In heating mode, it can replace the boiler system to avoid smoke-pollution. In cooling mode, it can avoid noise and leaf mold from cooling tower to protect environment.

Energy saving:In winter, user can get 5KW heat power with 1kw electrical power. In summer, uses can get more than 6KW cooling power with 1kw electrical power. The efficiency is 3-4 times as that of electrical heater.

Space-saving:No need of Boiler and relevant equipment, by which can save space.

Water-Saving:Cooling or heating can be realize by discharging or absorbing power into the water; water source will not be consumed neither be polluted.

Money-saving:Cooling or heating can be realized by one system; its investment is 1/2-2 of that of traditional equipment.
