Abstract
An improved, energy-efficient HVAC system and method of use employing a solution that is run parallel to refrigerant lines in a chiller unit. The solution is directed through the chiller unit through its proximity to chilled refrigerant wherein the chilled solution, rather than refrigerant, enters an air handler or an air pump and used to adjust the air temperature to a desired level. The system and method permits the place of a refrigerant based system external an enclosed building and a non refrigerant based system position internal the enclosed building.
Claims9
An improved HVAC system comprising:
- a first closed loop for recirculation of a refrigerant,
- at least one compressor fluidly coupled to said pump, said compressor having an inlet for receipt of low-pressure refrigerant gas and an outlet for directing high pressure refrigerant gas;
- a chiller having a refrigerant inlet coupled to said outlet of said compressor, said chiller constructed and arranged to reduce the refrigerant pressure causing evaporation as heat is extracted, said refrigerant is expelled from said chiller coupled to said compressor to provide recirculation;
- a second closed loop having a pump fluidly coupled to a cooling inlet of said chiller, said cooling inlet receiving a biodegradable fluid solution capable of cooling faster and maintaining a stable temperature longer than the refrigerant gas in the first closed loop;
- and
- an evaporator coil positioned within an interior of a building for receipt of said solution from said chiller for use in regulating the air temperature within the conditioned space of the building, said solution returned to said pump to provide recirculation.
A method of improving an HVAC system comprising the steps of:
- forming a first closed loop having a first pump to transfer refrigerant;
- directing said refrigerant from at least one compressor for phase changing said refrigerant into a high pressure gas;
- cooling said refrigerant gas by a chiller constructed and arranged to reduce the gas pressure with evaporation and extracting heat;
- returning said refrigerant expelled from said chiller to said pump to provide recirculation;
- forming a second closed loop having a second pump to transfer a solution;
- directing said solution to a cooling inlet of said chiller, said solution capable of cooling faster and maintaining a stable temperature longer than the refrigerant and is moved at temperatures ranging from 26-50 degrees F. at a pressures less than 40 pounds;
- transferring said solution from an outlet of said chiller to an evaporator coil positioned within an interior of a building for use in regulating the air temperature within the conditioned space of the building;
- and
- recirculation of said solution.
