Getting a brand new heat pump service – UAE | Viessmann

The heat pump works on the same principle as the refrigerator, which keeps your food cold not by pumping cool air, but by pumping warm air. The heat you feel outside the machine is actually transmitted. Similarly, a heat pump can cool a building by releasing hot air. Or, in winter, a heat pump can heat a building by acting as a “back-up refrigerator,” absorbing heat even in cold air and bringing it inside. (That puts you simply - the engineering involved is complex.)

"The air may be very cold, but it transfers heat to the cold air to your house," said Randal Newton, vice president of engineering at Trane Technologies, which makes heat pumps. “Your refrigerator is cold, and it still heats up the heat in your kitchen in that cold box.”Home heat pumps can also apply to geothermal energy in the back of your house. Instead of exchanging heat and air, the geothermal pump uses plastic pipes buried in the yard to exchange heat with the earth itself. (You do not have to sit on a hot spring; once it is four or five feet deep, it stays at a constant temperature for a whole year.)

Thermometric coolers electric heat pumps. A thermoelectric cooling system typically uses a matrix of semiconductor pellets connected between two large electrodes. When a DC power source is connected between electrodes, the badly charged side becomes cooler, while the well-charged side becomes hotter than the input temperature.

The negative side is placed connected to the component, device or medium for cooling, while the positive side is connected to the cooling component, such as a heat sink, which emits light or dissipates thermal energy to the external surface. Thermo electrics can be obtained with a combined size of microelectronics cooling and a number of scientific applications.

Thermo acoustic heat pumps use heat conversion to acoustic vibration. The main force behind thermo acoustics is heat transfer and wave propagation. Thermo acoustic cooling is used in cryogenics.

Magnetic heat pumps use the ability of a set of magnets to transfer heat from the cooler side to the heating side. Heat is transferred to a ferromagnetic mixture that is transferred from the cooling system to the outer surface where the heat emits. This is a field for further testing but it is estimated that magnetic heat pumps can improve refrigeration efficiency by as much as 40 percent.

Designing and operating your heat pump system:

                                                                                                                        

While we can control the temperature of an external source, we can also design heating systems that use low-temperature water in the house, which means that the heat pump can use less electricity and heat your home more comfortably.

By using radiators with a larger area, or lower temperature, more heat can be brought into the room without increasing the water temperature. Using a long-term heating system is another way to bring more heat into a room with low-temperature water.

If you have radiators with limited space, then the heat pump will need to operate at high temperatures. This means that the compressor works hard to deliver the same amount of heat as it would with large radiators, or if it has a long operating life. When a compressor works hard, it uses a lot of electricity, which makes the system very expensive to operate.

The purpose of a well-designed system is to reduce the temperature of the hot water as much as possible. If the required temperature is close to the source temperature (i.e. outdoor air or low temperature), then the heat pump will be more efficient, and as a result operating costs are reduced.
