Air To Water Heat Pump Cop

Typically air to water heat pumps have a cop of around 3 which means they generate three units of heat for each unit of electricity used.

Air to water heat pump cop.

I recently ran an analysis of two heat pumps. It s very useful when comparing heat pumps fridges and air conditioners. The efficiency of an air to water heat pump is most optimal at 7 c as opposed to dry and cold locations where outside temperatures fall below 20 c. Both heat pumps were assumed to supply heat to an energy efficient house in a cold upstate ny climate of 6720 heat degree days.

By definition cop is the ratio of how much useful heat or cold an hvac device will produce if we give it certain energy input. The coefficient of performance cop describes the amount of heat that a heat pump can produce compared to how much energy has been put in at any given time. The cop of a geothermal heat pump is the ratio of the heating or cooling output to the energy input to run the machine.

An air to water heat pumps system consist of four major elements that allow the refrigerant to pass from the liquid state to the gas. Within temperature ranges of 3 c to 10 c the cop for many machines is fairly stable at 3 3 5. The efficiency of air source heat pumps is measured by the coefficient of performance cop. A cop of 3 means the heat pump produces 3 units of heat energy for every 1 unit of electricity it consumes.

Geothermal heat pump efficiency is traditionally measured using a ratio called coefficient of performance cop. A high cop over 1 0 means your heat pump is performing very efficiently and your heating bills will be low. A fan passes air over the evaporator the refrigerant absorbs heat from the outside air. The cop varies according to the external temperature becoming less efficient when the weather is really cold.

Cop or coefficient of performance is the most basic energy efficiency metric of any heat engine. This type of heat pump works best in moderate climates. A heat pump is a device that transfers heat energy from a source of heat to what is called a thermal reservoir heat pumps move thermal energy in the opposite direction of spontaneous heat transfer by absorbing heat from a cold space and releasing it to a warmer one a heat pump uses external power to accomplish the work of transferring energy from the heat source to the heat sink. However air source heat pumps do perform strongly all year round and have proven popular in.

For example if a heat pump has a cop of 5 the pump can produce 5 units of heat for every watt of power used. The report will show the projected performance capacity cop seasonal average cop cop by hours and by temperature a backup heat analysis and more. A compressor a condenser an expansion valve and an evaporator. A geothermal heat pump with an assumed seasonal average cop of 4 0 and a cold climate air to water heat pump with a seasonal average cop of 2 5.
