Water Source Heat Pump System With A Cooling Tower And Boiler

While eliminating both the cooling.

Water source heat pump system with a cooling tower and boiler. A water source heat pump system would also provide heat utilizing the. Heat pumps can be applied in many situations where low temperature heat is freely available and a load is present to accept that heat at a higher temperature. Heat pumps are used for space heating domestic water heating heat recovery ventilation and even recovering useful heat from sewer effluent. This gives individual and specialized zone control for maximum comfort and the ability to change operation modes as needed.

Ground source heat pump systems offer the potential for saving energy because they can reduce or eliminate the energy needed to operate a cooling tower and or boiler. Many new condos and commercial buildings use water source heat pumps for heating and cooling. Water source heat pumps can be thought of as reversible refrigeration units. They all have the capacity to drain the condensate from the boiler.

Keeping the water loop temperature in this range is a matter of economics and engineering judgment. Eliminating the cooling tower has architectural and maintenance advantages and eliminating the boiler frees up floor space in the building. Chilled water distribution systems can use the same pipe system as the hot water heating systems. As the most energy efficient hvac systems on the market water source heat pumps wshps are uniquely simple in design.

A system that is similar to a chilled water system is a water source heat pump system. Water source heat pumps also operate at lower condensing temperatures because they are linked to the outdoor wet bulb temperature using a cooling tower or the deep earth temperature using a ground heat exchanger instead of the higher outdoor dry bulb temperature again leading to higher efficiencies and longer s. Water source heat pump systems with a cooling tower and boiler 1 vav system with packaged rooftop unit packaged rooftop units rtus normally include a condenser for air conditioning and a gas or electric boiler for space heating. Water source heat pump systems are an ideal application for condensing boilers.

Each unit is an independent packaged system eliminating the chance of a total system failure. These systems are called geothermal systems. The cooling tower pumps and boiler are located away from occupied spaces. Water source heat pump systems would also typically have a cooling tower but no chiller.

Water source heat pumps can effi ciently operate in either heating or cooling mode under these conditions. Heat is moved through an interconnected water loop and either rejected through a cooling tower or put to work in other areas. This system typically includes a boiler also called a heat adder a cooling tower also called a heat rejecter pumps and controls as shown in figure 1.
