Heat pumps are not a new invention. The basic principle is that it absorbs heat from the air surrounding and inside your home and removes it. Following that, the unit’s compressor pumps refrigerant between two coils for heat exchange. The refrigerant evaporates, and the first coil absorbs the heat. If you believe that refrigerators and air conditioners do the exact opposite, you are correct. However, a heat pump like the luft til vand varmepumpe which you can find on various websites such as amalo.dk, which generates and circulates heat inside your home, can also reverse the process, transforming heated air to frigid air. To make the shift, the unit’s reversing valve is used. Furthermore, these heat pumps are available on various websites such as Amalo.
A heat pump in heating mode works similarly to a heat pump in cooling mode, with the exception that the refrigerant flow is reversed via the aptly named reversing valve. The heating source becomes the outside air, and the heat energy is released within the home as a result of the flow reversal. The exterior coil now serves as an evaporator, while the indoor coil now serves as a condenser. The process’ physics are identical. Cool liquid refrigerant absorbs heat energy in the outdoor unit and converts it to chilly gas. The cold gas is then turned into hot gas by applying pressure to it.
Steps of how heat pumps work
At the indoor coil, which serves as the evaporator, liquid refrigerant is pumped. Heat energy is absorbed by the refrigerant as air from within the house is blasted through the coils. The air which is cool is pumped throughout the ducts of the house as a result. Liquid refrigerant has heated up and evaporated into gas as a result of absorbing the heat energy.Â
The gas form is now pressurized. The pressurisation of the gas form increase the temperature which heats it up. The hot, pressurised refrigerant makes its way to the outdoor unit’s coil.
The refrigerant then, cools down until it becomes liquid state when it cools throughout this process. Warm liquid refrigerant then, is delivered to the units’ expansion valve which is indoor.
Expansion valve lowers the pressure, greatly lowering its temperature. The process has been completed because the refrigerant has gone into a liquid as well as cool state. It will be pumped back again to restart the process.
One of the most important things to remember about heat pump operation and the heat transfer process is that heat energy is drawn to locations with lower temperatures and lower pressure. Heat pumps rely on this physical property to transfer heat by bringing it into contact with cooler, lower-pressure environments. A heat pump operates like this.
A HEAT PUMP SYSTEM’S IMPORTANT COMPONENTS
An exterior unit as well as an inside air handler unit make up a conventional air source heat pump system. Various significant sub-components can be found in both the indoor as well as outdoor units.
