subject: How Heat Pumps Can Cool Too? [print this page] Heat pumps are available in many options and sizes. Various types of heat pumps can be used, such as air source heat pumps. These units run on electricity and are more efficient than units that use gas. The heat pump has an indoor unit and an outdoor unit. Air source heat pumps keep your home warm during winter and cool during the summer.
The installation of this heat pump offers you many benefits. These units will deliver up to 3 times more energy than the amount of electricity consumed. The unit produces heat during cold weather and air that is cool during hot weather. Air source units transfer energy and are not powered by fossil fuels. The use of a unit with an outdoor and indoor component is called a split system. A fan to distribute air is used in the home and a heat exchanger is used outside the home.
The air source unit for your home needs to be properly sized. If you have a unit that is too large, then it can cause excessive noise and reduce the comfort level in your home. The unit will also turn on and off more often and can lead to a reduced lifespan. A unit that is undersized will not be efficient as it cannot distribute the air properly. The unit will need to work harder and will lead to premature failure. When a new unit is being considered for your home, it needs to be sized by a professional technician.
There are six factors that are used to determine the size of equipment for your home. The first factor is the amount of insulation for your home. The second factor is the amount of leaking air out of windows and other areas. A third factor is the insulation and sealing of your existing ducts. A fourth factor is the total number of windows in the home and the direction they point. The fifth factor is any shade coming from trees and overhangs. The sixth factor is the orientation, layout and the size of your home.
The unit acts like an air conditioner during the summer months. Refrigerant is used to move heat that is inside your home to the compressor or heat exchanger outside. Coils inside the heat exchanger pull heat from the refrigerant, which is then returned to the house. This process cools the inside air.
If a split system is not the best option, then a packaged unit is available. This is a unit that has both the heat exchanger and the compressor or fan inside a self-contained unit. You can use this type of unit for cooling your entire house or to cool a single room.
