1. A heating and cooling system powered by renewable energy and assisted by geothermal energy, comprising:
a solar cycling unit, wherein the solar cycling unit comprises a first working fluid, a solar collector, a thermal energy storage (TES), a heat exchanger, and a first pump, wherein the solar collector, the first pump, and the heat exchanger are in fluid communication through a first piping system carrying the first working fluid, wherein the TES is in fluid communication with the first pump to provide the first working fluid to the first pump;
a supercritical carbon dioxide (S—CO2) cycling unit, wherein the S—CO2 cycling unit comprises a second working fluid, a second pump, a first condenser, and a turbine, wherein the second pump and the first condenser are in fluid communication through a second piping system carrying the second working fluid, wherein the second pump is operatively coupled with the turbine;
a refrigerant cycling unit, wherein the refrigerant cycling unit comprises a third working fluid, a compressor, a second condenser, an evaporator, and at least one expansion valve, wherein the compressor, the second condenser, the at least one expansion valve, and the evaporator are in fluid communication through a third piping system carrying the third working fluid;
the solar cycling unit being in thermal communication with the S—CO2 cycling unit through the heat exchanger, wherein heat absorbed by the first working fluid is transferred to the second working fluid at, the heat exchanger, wherein the second piping system passes through the heat exchanger and into the turbine; and
the S—CO2 cycling unit being operatively coupled with the refrigerant cycling unit to compress the third working fluid to produce a cooling effect;
a plurality of three way valves;
wherein the heat exchanger is in fluid communication with a first three way valve from the plurality of three way valves,
wherein the second pump is in fluid communication with a second three way valve from the plurality of three way valves,
wherein the first three way valve and the second three way valve are in fluid communication with a secondary heat exchanger,
wherein the first condenser is in fluid communication with a third three way valve from the plurality of three way valves and a fourth three way valve from the plurality of three way valves,
wherein the third three way valve and the fourth three way valve are in fluid communication with a tertiary heat exchanger through a tertiary pump,
the secondary heat exchanger and the tertiary heat exchanger being in fluid communication with a first geothermal heat exchanger through a fifth three way valve, a sixth three way valve, and a secondary pump wherein the fifth three way valve and the sixth three way valve are from the plurality of three way valves;
the refrigerant cycling unit further comprising a four way valve integrated into the third piping system;
wherein the second condenser is a second geothermal heat exchanger; and
the compressor, the four way valve, the evaporator, the at least one expansion valve, and the second geothermal heat exchanger being in fluid communication with each other through the third piping system carrying the third working fluid.
