Cooling Tower Water Source Heat Pump Diagram

The chiller condenser water heat is recovered instead of being rejected to the outside and used as a heat source for a water source heat pump system serving the perimeter spaces.

Cooling tower water source heat pump diagram.

The water supply may be a recirculating closed loop or a once thru system using water from a well a pond or a stream. Typical water source heat pump system. It must also provide the energy head necessary to raise water from a low to a higher static head. 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.

Water for closed loop heat pumps is usually circulated at 2 25. Hybrid systems composed of water source heat pumps and other types of hvac equipment however may be best suited to meet the specific requirements of a given building. As the most energy efficient hvac systems on the market water source heat pumps wshps are uniquely simple in design. Open piping circuit for the tower piping circuit the pump must overcome the piping flow friction loss.

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. Boiler horizontal wshps vertical stack wshps vertical wshps rooftop wshps pumps cooling tower figure 1. Cooling towers are also used in hvac systems that have multiple water source heat pumps that share a common piping water loop.

Closed loop heat pumps utilize a system in which there is a heat pump in each zone of a. If a building has a moderate amount of internal heat gain needs a heated and cooled environment and requires a minimum cooling capacity of 35 to 50 tons then the building should be seriously considered for the closed loop water source heat pump system. On the other hand cooling towers are much larger than tradional hvac systems and are used to remove heat from cooling tower water systems in petroleum refineries plants natural gas processing plants petrochemical plants and other industrial processes and facilites. The closed water loop provides condenser water to the interior zone cooling units picking up the heat normally rejected to a cooling tower and transferring it as.

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. Tradional hvac heating and cooling systems are used in schools large office buildings and hospital. In this type of system the water circulating inside the water loop removes heat from the condenser of the heat pumps whenever the heat pumps are working in the cooling mode then the externally mounted cooling tower is. Where available cold water readily available in nearby water bodies might be used directly for cooling replace or supplement cooling towers.

Water level pump suction water will reach this level without pump energy. Water source heat pump applications. The deep water source cooling system in toronto ontario canada is an.
