초록 ▼

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.

1. An improved HVAC system comprising: a first closed loop positioned outside a building interior for recirculation of a refrigerant gas positioned in a non-conditioned space wherein refrigerant gas does not enter said building interior, said first closed loop consisting of at least one compressor having an inlet for receipt of low-pressure refrigerant gas and an outlet for directing high pressure refrigerant gas through at least one condenser, said condenser includes a fan for passing ambient air across said condenser for dispensing heat contained in said refrigerant gas, said condenser converting high pressure refrigerant gas to liquid refrigerant;a chiller having a thermostatic expansion valve dissipating refrigerant pressure, said chiller constructed and arranged to reduce the refrigerant pressure causing evaporation as heat is extracted, said refrigerant liquid is expelled from said chiller and fluidly coupled to said compressor for recirculation;a second closed loop having a solution pump fluidly coupled to a cooling inlet of said chiller, said cooling inlet receiving a biodegradable solution consisting of properties capable of cooling faster and maintaining a stable temperature longer when recirculated at temperatures ranging from 26-50 degrees at pressures of 10-40 pounds per square inch wherein said compressor can operated with reduced head pressures which allows for lower start-up and running currents; andan 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 interior of the building, said solution returned to said solution pump to provide recirculation to said cooling inlet of said chiller;whereby said solution pump can continue to recirculate solution when said compressor is cycled off allowing temperatures in said building interior to remain relatively constant. 2. The improved HVAC system according to claim 1 including a control module to regulate said solution pump and said compressor. 3. The improved HVAC system according to claim 1 wherein said solution is formulated with a heat exchange rate exceeding that of water or air, wherein said evaporator coil conditions air between 50-55 degrees F. 4. The improved HVAC system according to claim 1 wherein said chiller functions as a heat exchanger wherein said solution is heated providing a heating cycle without the necessity of supplemental electric heat strips. 5. A method of improving an HVAC system comprising the steps of: forming a first closed loop to transfer refrigerant gas in a non-conditioned space wherein said refrigerant gas does not enter an interior of a building;directing said refrigerant gas through a compressor for phase changing said refrigerant gas into a high pressure refrigerant gas;passing said high pressure refrigerant gas through a condenser to dispense heat;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 provide recirculation through said compressor;forming a second closed loop in an interior of a building having including a solution 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 per square inch;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; andrecirculation of said solution through said second closed loop when said compressor is cycled allowing temperatures in said building interior to remain relatively constant. 6. The method of improving an HVAC system according to claim 5 including the step of heating said solution wherein said HVAC system operates as a heater. 7. The method of improving an HVAC system according to claim 6 wherein said solution and said step of heating is constructed and arranged to eliminate the need for electric heat strips.
