An Introduction to Heat Pump Efficiency - 

Heat pump   and boilers provide local heating by adding heat to the air through the combustion of fuels such as natural gas or heating oil. Although the performance is continuously improved, it is still less than 100%, which means that not all available energy from heat is used to heat the air

Heat pumps work with a different purpose. The heat pump in the heat pump is used to transfer heat energy between the two areas. This allows the heat pump to operate more efficiently, with normal efficiency gone. 100%, i.e. more heat energy is generated than the amount of electrical energy used to pump.

It is important to note that the efficiency of a heat pump depends largely on the temperature of the well and the sink. Just as a steep hill requires extra effort to ride a bike, the large temperature difference between the source and the heat pump sink requires it to work hard, and can reduce efficiency. Determining the correct size of heat pump to increase seasonal efficiency is important. These factors are discussed in more detail in the section of air source heat pumps and sub-heat pumps.

Efficiency Terminology –

A variety of efficient metrics are used in the manufacturer's catalogs, which can make understanding system performance somewhat confusing for the first-time consumer. Below is a breakdown of some of the most commonly used words:

State-State Metrics: These measures define the efficiency of a heat pump in a ‘constant state,’ that is, without the actual life fluctuations in season and temperature. Therefore, their value can change significantly as the temperature of the source and sink, as well as other operating parameters, change. Solid metrics include:

Coefficient of Performance (COP): COP is the ratio between the rate at which a heat pump transmits heat energy (in kW), and the amount of electrical energy required for boiler (in kW). For example, if a heat pump uses 1kW of electricity to transfer 3 kW of heat, the COP would be 3.

Energy Efficiency Ratio (EER): EER is similar to COP, and describes the cooling efficiency of the heat pump stability. It is determined by dividing the cooling capacity of the heat pump to Btu / h by the input of electricity to Watts (W) at a certain temperature. The EER is strongly associated with defining efficient cooling efficiency of the environment, in contrast to the COP which can be used to demonstrate the efficiency of heat pump for heating and cooling.

Seasonal Performance Metrics: These standards are designed to provide the best possible performance during hot or cold, by combining a variety of "real life" temperatures throughout the season.

Heating Seasonal Performance Factor  (HSPF): HSPF measures the amount of heat a heat pump brings to a building during the full heating season (in Btu), to the total energy (in Watthours) that it uses during the same period.

Long-term weather data features are used to represent the temperature in calculating the HSPF. However, this figure is usually limited to one area, and may not fully represent operations across UAE . Some manufacturers may provide HSPF in another climate zone upon request; but usually HSPFs are reported in Regional 4, which represents climates such as the Midwestern US. Region 5 will cover most of the southern part of the Canadian provinces, from mid-BC to New BrunswickFootnote1.

Seasonal Energy Efficiency Ratio (SEER): SEER measures the cooling efficiency of a heat pump throughout the cooling season. It is determined by dividing the cooling amount provided during cooling (in Btu) by the amount of energy used by the heat pump at that time (in Watt hours). SEER is based on a temperature range of summer temperatures of 28 ° C.

Low-cost systems will reduce your heating and cooling costs significantly. The cost of heating energy compared to an electric stove is about 65%.On average, a well-designed ground source system will bring about 10-20% savings more than would be provided by a high-quality cold air source heat pump in a classroom with a size to shut off most of the building's heat load. This is because ground temperatures are higher in winter than air temperatures. As a result, a low-temperature heat pump can provide more heat during the winter than an air source heat pump.

The actual energy savings will vary depending on the local climate, the efficiency of the existing heating system, the cost of fuel and electricity, the size of the installed heat pump, bore field suspension and seasonal power balance, and the efficiency of the heatpump. Conditions of measurement.
