How Heat Pumps Work | HVAC Heating Systems
Have you ever wondered how Heat Pumps work? Heat Pumps can be a very economical way of heating and cooling your dwelling. It depends on geographical location and the cost of electricity in your area. The volatile costs of natural gas, propane, and oil have enabled these conditions. Conditions where it can be cheaper with a heat pump than with fossil fuels.
There is a common conception that a heat pump blows cold air.
While this can be true in some cases it is not true. If a heat pump is blowing cold air when in the heating mode then it has a problem. A problem that needs to be corrected. Even when the outside unit kicks into the defrost mode the unit should provide adequate heating.
Heating to heat the zones which it serves. Again, if it is not providing adequate heating then it needs to be looked at for a technical problem. A problem that needs correcting. A well-designed system, working properly and efficiently, can provide competitive and economical heating. (more…)
Duct Temperature Sensor - The duct static temperature sensor measures air temperature in the ductwork. The solid-state temperature sensing devices are commonly used in HVAC applications that are controlled by direct digital control or a modern building automation system. At the base of the box is a probe that sticks into the air stream of the ductwork. As the air passes over it, the probe changes resistance.
