Heat pumps are devices designed to move thermal energy in the direction opposite that of spontaneous heat flow by taking in heat from a cold space and gently releasing it to a warmer space. In transferring the energy from the heat source to the destination known as the heat sink, a heat pump utilizes the same amount of power to accomplish the task.
Recent developments in the HVAC industry have increasingly focused on developing advanced features that improve the performance of heat pumps. This in turn guarantees homeowners comfort all-round the year. The advancement in features makes the heat pumps energy efficient and versatile in operation. Among the key features that manufacturers have been gradually improving include:
These are the core components of heat pumps and which primarily determines whether a heat pump is good or bad. The energy efficiency of the compressor, the durability of its mechanical parts and the quietness of operation are among the factors to look out for in selecting a compressor. Basically, a compressor helps in conveying the refrigerant in vapor form at low temperature and pressure to a high temperature and pressure stage. The force that moves the refrigerant against the gradient comes from an electric motor connected to the mains and integrated into the compressor.
Dual-speed compressors use less electricity because they run at slower speeds almost all the time unless there is extra conditioning required. This saves lots of energy. Scroll compressors are also a good choice in heat pumps because they are designed to last longer than the regular piston compressors. They also deliver between 10 and 15 degree warmer air compared to piston compressors during heating.
Heat pumps with variable motor speeds help in reducing noise during operation and evens out temperatures throughout your home. This is in sharp contrast to the traditional motors which only run at one speed to match the load. To understand it better, a variable speed motor can be compared to an accelerator pedal which enables the deliver to match and control the speed of the car to the exact needs or road conditions. Based on the load, they can either slow down or speed up. This gives you as a homeowner increased comfort as well as energy savings.
Every time heat pumps can’t extract sufficient heat from the outdoor coil in order to warm your home, the built-in electric resistance coil automatically turns on thereby giving backup heating. For colder temperatures, you can combine your heat pump with a combustion heating system in order to get the best out of it. When assembled this way, your heat pump will be able to switch to the gas furnace the moment outdoor temperatures fall to approximately 30 degrees and below.
The last thing you want in your residential heating system is heat wastage. To curb this, you can install heat pumps fitted with desuperheaters. These are secondary heat exchangers built in your heat pumps and help in tapping waste energy. This energy is then used in heating other parts of your home including hot tubs and swimming pools. In this way, you optimize your energy usage and get the comfort you need at a budget.
