A heat pump carries readily available heat from one place to another. An outdoor unit absorbs heat from the surrounding air and transfers it home. As the outside temperature decreases, it also transfers the same amount of heat inside the house. However, it provides heat inside your home in winter. And in summer it keeps the indoor environment cool in contrast.
By installing a heat pump you can keep your home environment comfortable in all seasons. In this article, we will discuss the work of a heat pump. Here you will get a complete idea about the work of each part of the heat pump. So if you want to know about Heat Pump you must read the full article.
Different types of heat pump
A heat pump works on both heating and cooling. It works like a refrigerator, using electricity to heat the pump from a cool place in winter. And it dissipates hot air in contrast to summer. There are mainly three types of heat pumps based on different heat sources. The three main types of heat pumps and heat sources are discussed below.
Such heat pumps work well in moderate climates using outside air as a medium of heat exchange. Also, it is cheap to install.
This type of heat pump is not a common heat pump. However, It requires access to a variety of water sources for this to work. It dissipates heat through the water.
It is also known as a geothermal heat pump to many. It takes advantage of the thermal energy stored underground, transferring the heat to the pumps. It is also relatively complex and difficult to install. It requires excavation and underground piping to install. Such heat pumps offer much more efficient operation.
Parts of a Heat Pump
A heat pump has many parts for heating or cooling the air. These parts work together for heating or cooling. Below are the different parts of heat pumps and their functions.
Compressor: This is a heat pump working principle. Heat pump compressors are quieter and have a longer lifespan. It stays in heating mode providing 10 ° to 15 ° F warmer air.
Control board: It is a board that controls the heat pump system.
Coils: It cools the air depending on the directional flow of the house heat or refrigerant.
Refrigerant: It circulates through indoor and outdoor units in the refrigeration line to cool or warm the air.
Reversing valves: Changing the flow of refrigerant determines whether the space is cold or hot.
Thermostatic expansion valves: It regulates the flow of water and the flow of the fridge.
The accumulator: It adjusts the refrigerant charge depending on the need.
Refrigeration lines and pipes: It connects internal and external equipment.
Heat strips: It is used to add extra heat on winter days or to recover quickly from low set back temperatures.
Ducts: It serves as an air tunnel in various parts of the interior of the house.
Thermostat or control system: Using it you can set your desired temperature
How does a heat pump work?
The heat pump works in two ways. It doesn’t just provide heat. It also works great to keep your home’s weather cool in the summer. Here’s how to put one together for use with a heat pump:
In heating mode, the outdoor unit of a heat pump absorbs heat energy from the outdoor air using refrigerant as the heat transfer medium. The hot refrigerant pumps to the indoor unit heat exchanger through copper pipes. As its hot air passes over the room heat exchanger the heat energy is transferred to the cooler indoor air. So, this causes the indoor weather to heat up. Here are some of the things that a heat pump does in heating mode:
- Even if the outside temperature is cold, the condenser coil absorbs sufficient heat from the outside air
- The indoor air of the house is drawn by a motorized fan
- The refrigerant absorbs heat from the air by pumping it from the inner coil to the outer coil
- Provides a consistent method to keep the house warm
The cooling mode of a hip pump uses refrigerant to cool the indoor air. However, its indoor unit heat exchanger is a heat exchanger medium used to absorb heat energy from indoor air. Also, the pump brings the copper pipe back to the outdoor unit. And its outdoor unit heat exchanger rejects heat energy to the surrounding air. Here are some of the things that a heat pump does in cooling mode:
- The warm air inside the house is drawn in by a motorized fan
- The compressor conducts refrigerant between indoor evaporation and outdoor condensation units
- Provides a consistent method of keeping the home weather cool
