How do Inverter Heat Pumps Work?
A heat pump works by using refrigerant to draw energy from the outdoor
air, bringing the air indoors to keep your home warm in winter. During the
summer months, however, you can reverse the cycle to remove the heat from your
home and cool the air inside.
Unlike standard air conditioners and furnaces, heat pumps give you a
high level of energy efficiency, which helps keep your monthly energy bills
low. Variable speed or variable frequency heat pumps maximize efficiency and
minimize energy lost during the refrigerant cycle.
How Inverter Heat Pumps Work?
When operating on a standard refrigerant cycle, the refrigerant level is
constantly flowing between the condenser and the compressor, converting the
liquid into a gas, depending on the temperature. The refrigerant cycle ends
once the air temperature in your home reaches a specific level you specify on
the thermostat, and only starts over if the temperature in your home changes.
Each time the cycle restarts, the system consumes energy to bring the
refrigerant to the proper temperature before starting the heating or cooling
However, when using an inverter heat pump, the refrigerant cycle will
run at different speeds depending on the heat load and temperature. You can
save energy with this system because the inverter automatically adjusts the
speed of the refrigerant and reduces starts and stops.
Pros and Cons
1. You will be able to minimise the amount of energy you lose while
riding, thereby reducing energy consumption and lowering your monthly heating
bill. This also has an impact on the environment, as you will reduce your
2. Because of the increased system efficiency, you can also maintain a
higher temperature for the cost you would otherwise pay to heat to a lower
3. Additional savings can come in the form of federal and state tax
credits, as inverter technology will significantly improve the energy
efficiency of your home.
1. People unfamiliar with HVAC terminology may confuse variable speed
heat pumps with similar terms used to describe heat pump blowers. Variable
speed blowers have some advantages of their own, but these are not relevant to
what we are mainly discussing in this article.
2. Certain types of variable frequency pumps will cost more than
standard models, meaning you have to pay higher upfront costs to benefit from
long-term savings, and they may require additional maintenance due to more
complex operating systems.
These are just some of the considerations to keep in mind when looking
at an inverter heat pump in your home.
