Heat Pump Cooling Mode

Controls whether the heat pump system should be in cooling heating or defrost mode.

Heat pump cooling mode.

If it is there may be a problem with the thermostat that s causing it to read the temperature incorrectly or an electrical. Many high efficiency heat pumps are equipped with a desuperheater which recovers waste heat from the heat pump s cooling mode and uses it to heat water. Heat pump not cooling. A desuperheater equipped heat pump can heat water 2 to 3 times more efficiently than an ordinary electric water heater.

This is the key difference between a heat pump and a standard air conditioner. In cooling mode a heat pump acts similar to a central air conditioner cooling a home by absorbing heat energy inside the home and releasing it outside the home as a compressor circulates refrigerant between the indoor air handler unit and the outdoor compressor. One direction for heating one direction for cooling. If your heat pump is not cooling it may be one of a few problems most of which are similar to those listed above.

This setting is important if you have a heat pump. Reasons a heat pump might not switch to cooling mode. Leave the default setting to o. If you have a heat pump and you notice that your system is cooling in heat mode and heating in cool mode change from the default setting to b.

When a heat pump is used for heating it employs the same basic refrigeration type cycle used by an air conditioner or a refrigerator but in the opposite direction releasing heat into the conditioned space rather than the surrounding environment. A heat pump in heating mode operates just like cooling mode except that the flow of refrigerant is reversed by the aptly named reversing valve. The heat setting will cause your heat pump to operate in heating mode and blow warm air instead but only if there is a call from the thermostat. The reversing valve is a component that changes the direction refrigerant flows through a heat pump after it exits the compressor.

As the heat pump draws moisture out of the air those within the home will see an immediate drop in perceived temperatures. The condenser and evaporating coil. Set the thermostat to cool mode a few degrees below your room s temperature so the thermostat calls for cooling. First check to see that your thermostat is set to cool.

The flow reversal means that the heating source becomes the outside air even when outdoor temperatures are low and the heat energy is released inside the home. When compared to a piston compressor scroll compressors are quieter have a longer lifespan and provide 10 to 15 f warmer air when in the heating mode. Some heat pumps contain a scroll compressor.
