Heat Pump Cooling Tower

In general adiabatic cooling can reduce operating costs by up to 30 percent compared with conventional open circuit cooling towers.

Heat pump cooling tower.

Also connected to this water loop are a heat rejecter e g cooling tower or geothermal heat exchanger a heat adder e g boiler or geothermal heat exchanger circulation pumps and related accessories. A cooling tower is a heat rejection device that rejects waste heat to the atmosphere through the cooling of a water stream to a lower temperature. 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. Plate heat exchangers with open circuit cooling towers.

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. Typically outdoor air is conditioned and delivered by a. The chiller adds heat to the condenser water and the cooling tower cools it down by rejecting this into the atmosphere. During operation heat is transferred from the warm fluid in the coil to the spray water and then to the atmosphere as a portion of the water evaporates.

Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet bulb air temperature or in the case of closed circuit dry cooling towers rely solely on air to cool the working fluid to near. For example if there is a moment when cooling and heating loads are equal this system can operate with both the boiler and cooling tower deactivated. A centrifugal pump moves water known as condenser water between the chiller in the basement and the cooling tower on the roof. It must also provide the energy head necessary to raise water from a low to a higher static head level.

Water source heat pump applications. An alternative to adiabatic cooling is to keep the conventional cooling tower but isolating it from the process or chiller plant with a plate heat exchanger. Piping condenser cooling tower losses and valves. Heat is moved through an interconnected water loop and either rejected through a cooling tower or put to work in other areas.

The need to install a dedicated heat pump for each building zone drives up the cost of these systems but this is compensated in the long term thanks to the superior energy efficiency achieved. As the most energy efficient hvac systems on the market water source heat pumps wshps are uniquely simple in design.
