Central heat pump system is designed to cool or heat a condition space by providing cooling in the summer and heating in the winter. The cooling is accomplished by metering liquid refrigerant with the use of a metering device to control the amount of liquid refrigerant entering the evaporator. This liquid then evaporates by absorbing heat from the condition space by the use of a fan motor. The refrigerant at this stage turns to low pressure gas, which then travels back to the compressor to be compressed and starts the process all over. The heating process occurs in the opposite way by the use of a four way reversing valve. This valve changes the flow of the refrigerant so that the system is now conditioning the outside or pulling heat from the outside (due to the refrigerant being colder than the outside temperature) and dumping it inside the space.
Heat Pump operates by transferring heat energy from a source of heat to what is called a heat sink. 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. When discussing heat pump efficiencies, the following terms are commonly used: coefficient of performance (COP), seasonal coefficient of performance (SCOP) and seasonal performance factor (SPF). The more efficient a heat pump is, the less energy it consumes and the more cost-effective it is to operate. There are several factors that will affect the efficiency of a system such as heat pump service, repair, install, climate, temperature, auxiliary equipment, technology, size and control system.
Heat Pump Service, Repair and Install
Heat Pump Service – it is recommended by the manufacturer to have your system inspect and service once per year.
Heat Pump Repair – repair should be done by a certified individual or contractor.
Heat Pump Install – install must be done properly for the unit to perform at the highest efficiency.
