Cooling Tower Water Source Heat Pump Diagram

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.

Cooling tower water source heat pump diagram.

The deep water source cooling system in toronto ontario canada is an. Typical 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. Water for closed loop heat pumps is usually circulated at 2 25.

Cooling towers are also used in hvac systems that have multiple water source heat pumps that share a common piping water loop. 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. Boiler horizontal wshps vertical stack wshps vertical wshps rooftop wshps pumps cooling tower figure 1. Heat is moved through an interconnected water loop and either rejected through a cooling tower or put to work in other areas.

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. As the most energy efficient hvac systems on the market water source heat pumps wshps are uniquely simple in design. Piping condenser cooling tower losses and. 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.

The water supply may be a recirculating closed loop or a once thru system using water from a well a pond or a stream. 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. Water source heat pump applications. Open piping circuit for the tower piping circuit the pump must overcome the piping flow friction loss.

Water level pump suction water will reach this level without pump energy. 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. Where available cold water readily available in nearby water bodies might be used directly for cooling replace or supplement cooling towers. 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.

Closed loop heat pumps utilize a system in which there is a heat pump in each zone of a. It must also provide the energy head necessary to raise water from a low to a higher static head. From one medium to another.
