Each unit is an independent packaged system eliminating the chance of a total system failure.

Water source heat pump design. The most reliable source is the soil and groundwater due to their. The aim of the design stage is to turn the outline specification produced at the feasibility stage into a full system specification and set of drawings so the system can be built. Heat is moved through an interconnected water loop and either rejected through a cooling tower or put to work in other areas.

The Star Renewable Energy homepage showcasing our range of high efficiency designed and manufactured heatpumps. The closed loop water source heat pump concept provides an extremely simple highly flexible and unusually reliable semi-decentralized system approach to year-round space conditioning of multi-room buildings. The water loop is piped through a building and each Heat Pump is connected individually.

The water supply may be a recirculating closed loop or a once-thru system using water from a well a pond or a stream. A typical commercial GSHP installation will extract heat from the ground by circulating water through an array of closed loop vertical boreholes of up to 200 metres in depth. Simple in design a WSHP rejects heat in the cooling cycle through a Cooling Tower loop.

Water source heat pump design. Heat pumps work by running a low-temperature lower pressure refrigerant fluid in heat exchanger coils through a heat source such as the outside air the ground or circulating water. A water source heat pump operates much like a traditional air source heat pump except that it extracts and dissipates heat by way of water instead of air.

Air to Water Heat Pump Design Heat Pump Design Guide There are multiple benefits when using an air source heat pump to heat your home with radiant heat instead of a forced air furnace which is exactly why we utilize an air to water system instead of a conventional air to air mini-split system like most of our competitors. Detailed specification of all Mechanical Electrical ME plant. Open loop systems can present particular challenges and will require the services of a specialist.

A heat pump is a device that transfers heat energy from a source of heat to what is called a thermal reservoirHeat 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 oneA heat pump uses external power to accomplish the work of transferring energy from the heat source to the heat sink. Cold water from the heat pump picks up heat from the ground as it circulates through the pipes in the ground by heat exchange. This mean that for 1 W of electric energy heat pump transfer from the ground 3 W of geothermal additional energy which if we neglect loses is equal to the 4 W of thermal energy.

The design and installation of ground source systems should be undertaken with care and attention. We provide Bespoke heatpump design for the UK and beyond and offer information on how heatpumps work and the benefits of water source renewable energy.
