Water To Air Heat Pump Schematic

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.

If either flow stream is restricted the heat pump quickly shuts itself off due to refrigerant pressure limits. Domestic heaters that are powered by oil gas and electricity heat water up to around 70 80 c whereas ground or air source heat pumps used for hot water may only be efficient up to 55 c.

Flow to all heating and cooling zones is provided by a single variable speed. 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. Colmac heat pump water heaters offer commercial and industrial users of sanitary hot water an energy efficient means of heating water to temperatures as high as 185 f 85 c in a single pass. Even if it s cold outside abundant warmth still exists in outdoor air.

Therefore increasing the surface area of your emitter system larger radiators and or underfloor heating and minimising the heat loss wherever possible. As can be seen energy from the storage unit is directly supplied to the building when the temperature of the water in the storage. These heat pump water heaters use the same operating principle as an air conditioner or domestic refrigerator. Flow starvation can occur when the heat pump serves a zoned hydronic distribution system.

Water to water heat pumps require constant water flow through both the evaporator and condenser while operating. These units work in a similar manor but without the reversing valve. The high pressure high temperature vapour refrigerant leaves the compressor but this time heads into a plate heat exchanger. The arrangement in figure 13 is a series configuration and the heat pump evaporator is supplied with energy from the solar system.

An air source heat pump absorbs warmth from outdoor air and transfers it inside your home. Colmac heat pump water heaters. Both zones must operate in the same mode e g heating or cooling at the same time. A hydronic heat pump has many advantages over conventional air to air heat pumps.

By storing the heat energy we can distribute it to any source we want such as a domestic hot water heating and cooling fans finned radiators hydronic in floor heating.

On the other side of the plate heat exchanger water is being cycled through a hot water storage tank.
