Water to Water Heat Pump Features:

1) Acting as multi-function unit such as cooling, heating, sanitary hot water separately or simultaneously. Wide application as hotel, apartment, villa, factory, shopping center, office building, school, etc;

2) Large capacity range available from 150 kW to 3000 kW; To be air conditioning and hot water;

3) Reusable: using solar energy stored in earth or groundwater, surface water etc as cooling & heating source;

4) Great environmental and economic benefit: no boiler or cooling tower; less space, less CO2 and less initial investment;

5) Semi-hermetic screw compressor for all the models. Each compressor is equipped with a crank-case heater and a thermal overload cut-out; the screw compressor is also complete with a built-in electronic protection with temperature sensor located;

6) The refrigerant circuit is complete with sight glass, filter drier, high and low pressure gauges, solenoid valve, direct expansion valve, high and low pressure switch;

7) Shell and tube dry expansion type condenser, factory insulated with flexible close cell material;

8) Shell and tube type evaporator, in the factory insulated with flexible close cell material;

9) The electric panel consists of compressor breaker, compressor contactor, phase sequence relay, control circuit breaker, microprocessor control with function display;

10) LCD display, touch screen control panel; Automatic operation dramatically reducing maintenance cost thanks to reliable microprocessor system;

11) For the units with semi-hermetic screw compressor, an infinitely variable capacity control system that is capable of exactly matching the demand requirement of thesystem is to be supplied. This system is to provide precise and stable control of supply water temperature over the complete range of operating conditions;

12) OPTIONAL

Electronic expansion valve

Desuperheater as optional

Electronic controller with BMS system

Low noise compressor cabinet

Channel Steel base

Geothermal Water to Water 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 to Water 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.

Water to Water 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.
