Abstract

An energy recovery system for a pre-existing condenser unit is provided. The energy recovery system provides a casing housing a coil fin, an external water source fluidly coupled to the coil fin, and the casing directly connected to the pre-existing condenser unit so that latent heat output from the pre-existing condenser unit interfaces with the coil fin for heating the external water by way of heat transfer. The energy recovery system is self-activating by electrically coupling a transformer of the energy recovery system to a power source of the pre-existing condenser.

Claims (12)

1 . An energy recovery system for a pre-existing condenser unit, the energy recovery system comprising:

a casing housing a coil fin;

an external water source fluidly coupled to the coil fin;

the casing directly connected to the pre-existing condenser unit so that latent heat output from the pre-existing condenser unit interfaces with the coil fin so that the coil fin heats the external water;

clamps directly connecting the casing to the pre-existing condenser unit;

a transformer electrically powering the coil fin;

an air temperature sensor configured to sense temperature of the latent heat output;

a temperature sensor configured to sense temperature of the external water source;

a water inlet through which the external water source enters the coil fin; and

a valve operatively associated with the water inlet;

wherein the control panel is configured to bypass, by way of the valve, fluid coupling of said water to the coil fin if a temperature of the external water is greater than or equal to a temperature of the latent heat.

2 . The energy recovery system of claim 1 , wherein the control panel further comprises a transformer electrically powering the coil fin, and wherein the transformer is electrically connected to a power source of the pre-existing condenser unit, whereby self-activation is enabled.
