Abstract

Claims (20)

1. An energy transfer module coupled to a thermal solar module, the energy transfer module comprising:

a body including a first end member, a second end member, and four side members configured to enclose a first spatial region within a vicinity of the first end member and a second spatial region within a vicinity of the second end member, the first spatial region being in communication with the second spatial region;

one or more inlet openings provided at the first end member for inputting fluid flow from the thermal solar module;

an air filter disposed within the first spatial region to remove one or more impurities from the fluid flow;

a fan disposed between the first spatial region and the second spatial region to draw the fluid flow through the air filter and a heat exchanger, the fan coupled to a drive motor;

the heat exchanger disposed in the first spatial region and having an inlet port and an outlet port coupled to a tank, wherein the tank contains a heat exchange medium configured to flow through the heat exchanger;

an outlet provided on the second end member;

a first temperature sensor disposed in front of the heat exchanger for measuring inlet air temperature, a second temperature sensor disposed behind the heat exchanger for measuring outlet air temperature, and a third temperature sensor for measuring a heat exchange medium temperature in the tank; and

a controller coupled to the first temperature sensor, the second temperature sensor, and the third temperature sensor for determining information about energy transfer from the thermal solar module through the heat exchanger via the one or more outlet openings,

wherein the controller to generates a control signal for driving the fan based on at least a temperature load, the temperature load including measurements from the first temperature sensor, the second temperature sensor, and the third temperature sensor.

2. The energy transfer module of claim 1 wherein each of the one or more inlet openings comprises a collar for coupling to an insulated flexible duct connected to the thermal solar module.

3. The energy transfer module of claim 1 wherein the fan comprises backward curved impellers with continuous duty to drive the airflow with a range of static pressures including an inlet pressure in the first spatial region and an outlet pressure in the second spatial region.

4. The energy transfer module of claim 3 wherein the range of static pressures is measured by 0.1 to 1.50 ft of H 2 O column.

5. The energy transfer module of claim 1 wherein the drive motor is disposed by a gauge mounting bracket coupled at least partially to the four side members.

6. The energy transfer module of claim 1 wherein the air filter comprises a two-inch thick pleated MERV 7 air filter with air filtration rate up to 900 CFM.

7. The energy transfer module of claim 1 wherein the heat exchanger comprises a coil made by two rows of aluminum finned copper tube for transferring heat carried by the fluid flow to water within the copper tube.

8. The energy transfer module of claim 7 wherein the copper tube comprises an entry port connected to a first water line to allow cold water being pumped from a water tank and an exit port connected to a second water line to output the heated water back to the water tank.

9. The energy transfer module of claim 1 wherein the outlet opening comprises a collar for coupling to a powered damper and ducting to either a conditioned space or an exhaust to outside.

10. The energy transfer module of claim 1 wherein the controller comprises a 30-120 VAC power supply for driving the motor with a modulated airflow from 30 to 100% of a predetermined rate.

11. The energy transfer module of claim 1 wherein the thermal solar module can be any combination of a photovoltaic panel, a thermal panel, an insulated glass panel, a heating pad.
