Benefits of technology
The present invention relates to a thermal energy storage system for an HVAC system, which maximizes efficiency and effectiveness. The invention involves the use of an evaporator core and a thermal energy exchanger in the air flow conduit of a control module. The evaporator core receives a first fluid from a first fluid source, while the thermal energy exchanger receives a second fluid from a second fluid source and a third fluid from a third fluid source. The second fluid absorbs thermal energy from a flow of air through the air flow conduit, while the third fluid releases thermal energy to the flow of air. This results in a more efficient heating and cooling of the passenger compartment of the vehicle. The invention also includes the use of a condenser downstream of the thermal energy exchanger to further improve the system's performance.
Problems solved by technology
However, in recent years, vehicles having improved fuel economy over the fuel-powered engine and other vehicles are quickly becoming more popular as a cost of traditional fuel increases.
Although the technologies improve fuel economy, accessories powered by the fuel-powered engine no longer operate when the fuel-powered engine is not in operation.

Embodiment Construction
[0019]The following detailed description and appended drawings describe and illustrate various exemplary embodiments of the invention. The description and drawings serve to enable one skilled in the art to make and use the invention, and are not intended to limit the scope of the invention in any manner.
[0020]FIG. 1 shows a heating, ventilating, and air conditioning (HVAC) system 10 according to an embodiment of the invention. The HVAC system 10 typically provides heating, ventilation, and air conditioning for a passenger compartment of a vehicle (not shown). The HVAC system 10 includes a control module 12 to control at least a temperature of the passenger compartment.
[0021]The module 12 illustrated includes a hollow main housing 14 with an air flow conduit 15 formed therein. The housing 14 includes an inlet section 16, a mixing and conditioning section 18, and an outlet and distribution section (not shown). In the embodiment shown, an air inlet 22 is formed in the inlet section 16....

A control module for a heating, ventilating, and air conditioning system includes a housing having an air flow conduit formed therein. An evaporator core is disposed in the air flow conduit, wherein at least a portion of the evaporator is configured to receive a fluid from a fluid source therein. An internal thermal energy exchanger is disposed in the air flow conduit downstream of at least a portion of the evaporator core and upstream of a blend door disposed in the air flow conduit. The internal thermal energy exchanger is configured to receive a second fluid from a second fluid source and a third fluid from a third fluid source, wherein the second fluid absorbs thermal energy from a flow of air through the air flow conduit and the third fluid releases thermal energy from the flow of air through the air flow conduit.
Description
FIELD OF THE INVENTION[0001]The invention relates to a climate control system for a vehicle and more particularly to a heating, ventilating, and air conditioning system of a vehicle having a thermal energy storage system.BACKGROUND OF THE INVENTION[0002]A vehicle typically includes a climate control system which maintains a temperature within a passenger compartment of the vehicle at a comfortable level by providing heating, cooling, and ventilation. Comfort is maintained in the passenger compartment by an integrated mechanism referred to in the art as a heating, ventilating and air conditioning (HVAC) system. The HVAC system conditions air flowing therethrough and distributes the conditioned air throughout the passenger compartment.[0003]Typically, a compressor of a refrigeration system provides a flow of a fluid having a desired temperature to an evaporator disposed in the HVAC system to condition the air. The compressor is generally driven by a fuel-powered engine of the vehicle....
