Air To Water Heat Pump Cop

Keeping the working principles of an air to water heat pump in mind the decline in temperatures will affect the operating efficiency.

Air to water heat pump cop.

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 manufacturer of the chiltrix cx34 air to water heat pump. Cop or coefficient of performance is the most basic energy efficiency metric of any heat engine. A compressor a condenser an expansion valve and an evaporator.

However air source heat pumps do perform strongly all year round and have proven popular in. 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. This report is powered by ashrae weather data viewer 6 0 under license between ashrae and chiltrix inc. A high cop over 1 0 means your heat pump is performing very efficiently and your heating bills will be low.

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. How does an air to water heat pump work. Geothermal heat pump efficiency is traditionally measured using a ratio called coefficient of performance cop.

The efficiency of air source heat pumps is measured by the coefficient of performance cop. I recently ran an analysis of two heat pumps. A fan passes air over the evaporator the refrigerant absorbs heat from the outside air. It s very useful when comparing heat pumps fridges and air conditioners.

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. Within temperature ranges of 3 c to 10 c the cop for many machines is fairly stable at 3 3 5. In very mild weather the cop of an air. The cop varies according to the external temperature becoming less efficient when the weather is really cold.

This type of heat pump works best in moderate climates. 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. 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.

A cop of 3 means the heat pump produces 3 units of heat energy for every 1 unit of electricity it consumes.
