Water Source Heat Pump Piping Diagram

Water source heat pump piping diagram.

Water source heat pump piping diagram. Piping connections are made directly to the heat exchanger coil and are 3 4 or 1 fpt. As the most energy efficient hvac systems on the market water source heat pumps wshps are uniquely simple in design. Selection of a water to water heat pump must be based on the source and load temperatures that occur at design load conditions on a particular project. Design of the closed system piping.

Water source heat pumps can operate in either cooling or heating mode with a common water loop. Raypak pool spa residential and commercial hydronic products. The access panel can be installed on the front of the unit as received or on the right side of the unit. The water supply may be a recirculating closed loop or a once thru system using water from a well a pond or a stream.

Those units which are not in operation. Heat pumps ground loop design simplicity one pipe systems 15. Water for closed loop heat pumps is usually circulated at 2 25. It is typical to pump away from the electric water heater or heat exchanger as shown in the following diagram.

A water to water heat pump with a given heating capacity under favorable water temperatures can have less than half this capacity under more demanding conditions. Hot water unit heater piping diagram. A water source heat pump extracts heat from the water when in the heating mode and rejects heat to the water when in the cooling mode. Water piping to and from the unit enters the unit casing through the water access panel.

Figure 1 shows a piping schematic for an air to water heat pump system that provides zoned heating using radiant panels and zoned cooling dehumidification using small air handlers. Heat is moved through an interconnected water loop and either rejected through a cooling tower or put to work in other areas. From one medium to another. If a system uses water source heat pumps instead of fan coils it can offer the advantages of a four pipe system while relying on a single hydronic piping circuit.

Those areas with high heat gains are rejecting heat to the water loop which is being pumped to the zones that are extracting heat. How ever it is also satisfactory to connect the water heater in the main from the heat pumps just before the water cooler. As the diagram indicates figure 3 the unitary heat pumps can be in all modes of operation simultaneously. Both zones must operate in the same mode e g heating or cooling at the same time.
