Heat is moved through an interconnected water loop and either rejected through a cooling tower or put to work in other areas.
Commercial water source heat pump system diagram.
Water source heat pump systems generally cost less to install than a central built up system.
Commercial water source heat pumps can be applied to geothermal closed circuit or open well loops or on a traditional boiler tower loop system.
The main switch ms must be closed to provide power to the control.
Water for closed loop heat pumps is usually circulated at 2 25.
The lon controller is an interoperable lonmark compliant controller with factory loaded application specific software which allows control of our heat pumps in buildings that require ddc control.
Jet pumps are mounted above the well either in the home or in a well house and draw the water up from the well through suction see single drop jet pump system diagram on next page.
The air to water heat pump and circulator p1 are powered by a dedicated 240 120vac 30 amp circuit.
The heat pump disconnect switch hpds must be closed to provide power to the heat pump.
From one medium to another.
The remainder of the control system is powered by 120vac 15 amp circuit.
The industry s only water source heat pump with automatic 3 speed fan control provides greater and more versatile comfort control than its 2 speed counterparts an economical approach for comfort conditioning requirements in both traditional and geothermal replacement renovation and new construction applications.
The water supply may be a recirculating closed loop or a once thru system using water from a well a pond or a stream.
Air source heat pumps can be found for much cheaper averaging around 1 500 to 4 000 because the units tend to be simpler and installation is easier.
A heat pump is a device that transfers heat energy from a source of heat to what is called a thermal reservoir heat pumps move thermal energy in the opposite direction of spontaneous heat transfer by absorbing heat from a cold space and releasing it to a warmer one a heat pump uses external power to accomplish the work of transferring energy from the heat source to the heat sink.
There are also rooftop and unit ventilator type water source heat pumps.
Expect to pay as much as 5 000 to 7 500 for a ground source heat pump system.
That can get a little pricey depending on the terrain on your property.
Water source heat pumps can be suspended in the ceiling plenum floor mounted behind walls or placed directly in the occupied space as a console unit.
As the most energy efficient hvac systems on the market water source heat pumps wshps are uniquely simple in design.
Each unit is an independent packaged system eliminating the chance of a total system failure.
