Water Source Heat Pump Vs Chiller

Water source heat pumps can operate in either cooling or heating mode with a common water loop.

Water source heat pump vs chiller.

Implement a water source heat pump system to meet simultaneous heating and cooling demand. Examine how water source heat pumps can reduce building energy consumption. Like air source heat pumps water source heat pumps are slightly more efficient at cooling rather than heating as even deep water will eventually get cold during the winter months. Heat is moved through an interconnected water loop and either rejected through a cooling tower or put to work in other areas.

Water source heat pump boiler cooling tower are the preferred method right now. Water source heat pump applications. The best features of both systems. 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.

Manufactures water to water heat pumps and water source heat pumps since designing our first modular chiller over ten years ago we ve brought our vast knowledge gained over 40 years of process chiller design to the design of our heat pumps for alternative sources of cooling. I know 10 years is way short with what can be expected. Air source heat pumps have an efficiency that ranges from 150 to 300 percent while a geothermal heat pump s efficiency can reach 600 percent in the heating mode. If it is being used to heat a building the refrigerant in the outside coils extracts heat from the air and evaporates into a gas.

However the water is still often warmer than the air and so water source heat pumps can be a good alternative if you live in a slightly cooler climate. As the most energy efficient hvac systems on the market water source heat pumps wshps are uniquely simple in design. The federal government is making tax credits available for geothermal heat pumps through december 2016. Like a chiller a heat pump consists of a compressor and a heat exchanger that transfers heat from the surrounding air to the refrigerant.

We are looking for maintenance type numbers or if someone has done a comparable life cycle cost analysis. Heat pump heat recovery chiller specifically designed to chill water provides a percentage of heat as warm water capacity controlled by leaving chilled water temperature condensing temperature is uncontrolled. An ashrae document showing life span of equipment 2011 lists commercial heat pumps with 24 years. 2013 heat recovery vs.

A new type of heat pump for residential systems is the absorption heat pump also called a gas fired heat pump.
