Reversible Heat Pump Mean?
A reversible heat pump is simply a water to water heat pump that functions as a heater and cooler. The primary source of heat for this system is derived from the sewage system which is considered to be a major source of heat loss in cities. This system is much more economical than the popular separate heating and cooling system that are widely used. Though using the sewer system as an energy source has its challenges, it is an environmentally friendly way of recycling energy.
Trenchlesspedia Explains Reversible Heat Pump
Reversible pumps can be used for both cooling and heating purposes and can be very economical when used in combination as a cooling-heating machine. It work by reversing the flow of the refrigerant from the compressor through the condenser and evaporation coils. In the heater mode, the indoor coil becomes a condenser while the outdoor coil acts as an evaporator through which the refrigerant conveys the thermal energy to the indoor coil. The thermal energy is then transferred to an air handler or to water which is then used for various heating purposes. In the cooling mode, the indoor coil acts as the evaporator while the outdoor coil acts as the condenser making it act as an air conditioner.
