When it comes to heat pump systems, now we’re talking about the heat. Straight cool systems are not equipped to reverse the flow of refrigerant to generate heat.
You had me with HEAT
In heating mode, the heat pump reverses the refrigeration cycle to extract heat from the outdoor air and transfer it indoors. The process begins with the outdoor coil acting as the evaporator, absorbing heat from the outdoor air despite cold temperatures. The refrigerant then travels to the indoor coil, now acting as the condenser, where it releases the absorbed heat to warm the indoor air. A blower fan circulates the heated air throughout the building.
Refrigerant Flow Reversal: Heat pumps are equipped with a reversing valve that switches the direction of refrigerant flow between heating and cooling modes. This valve allows the heat pump to provide both heating and cooling functions without the need for separate systems.
Want more? I thought so. Next time we will introduce Thermostat Control and the concept of Efficiency.
