Chillers and Heat Pumps

Heat Pump Solutions

According to the Environmental Protection Agency ( EPA ), it is estimated that 5 % of the world ’ s daily energy consumption is expended on fuel for heating water . Additionally , in Western European countries , 25 % of primary energy used is for cooling and heating applications . As pressure continues on natural resources and energy bills continue to rise , we must seek new , environmentally friendly solutions .
One smart option is to improve the energy utilization of your facility ’ s heating and cooling system by recycling heat energy that would otherwise be rejected . This can be accomplished with a Johnson Controls heat pump .
At Johnson Controls we set standards without compromising our core principles : and when passion and innovation come together , great things happen !
What is a Heat Pump ?
Heat pumps are designed to produce hot water at a specified temperature . Heat is extracted from a low-temperature source such as air , ground water , or waste process heat , and its temperature is raised to a level where it can be used in alternative processes .
There are 4 primary system designs for heat pumps : 1 ) Air-source – An example of this is the heat pump you may have in your home . 2 ) Ground-source – This system uses the ground as the heat source , often used in residential or light commercial applications . 3 ) Water-source – This system uses a building ’ s water supply to transfer heat . This is the most commonly used system . 4 ) Cascade-source – The system uses heat from existing refrigerant systems or any available waste heat source .

Traditionally , chillers are used to provide a building ’ s required cooling load ( rejecting heat to atmosphere via cooling towers ) and boilers supply hot water to meet the building ’ s heating needs . Using a Heat Pump gives increased system efficiency and lowers operating expense as they can supplement or even replace existing heating systems , and can also operate in reverse cycle to provide cooling during the summer . There are also processes in which cooling and heating functions perform simultaneously . Again , heat pumps are an ideal solution to this challenge .
