Dynamic fine-tuning refrigeration system
A dynamic refrigeration system may automatically, at pre-determined time periods on-the-fly, adjust a refrigerant system's refrigerant pressures to predetermined optimal efficiency pressures as the internal and external heat loads change over a range. This may result in the refrigerant system pressures closely operating within a range of predetermined optimal efficiency pressures. This system may automatically instantaneously fine tune and balance on all air conditioning, heat pump, and refrigeration systems as the internal and external heat loads are continuously changing dynamically. The system may include a small liquid refrigerant pump and refrigerant storage tank, one or more wired or wireless pressure transducers and temperature sensors, and a “brain” to make decisions to keep the system instantaneously set at factory specs all the time. The system may include a wireless communication means so it can instantaneously report its operating condition, loads, and cost of operating.
1 . A dynamic refrigeration control system that adjusts refrigerant pressure to match a refrigerant manufacturer's temperature-pressure chart comprising:
a refrigerant compressor;
a low pressure refrigerant port Schrader valve suction line running into the refrigerant compressor;
a high pressure refrigerant port Schrader valve;
a low pressure solenoid valve connected to the high pressure refrigerant port Schrader valve through a braided refrigerant flex hose;
a plurality of temperature sensors;
a plurality of pressure sensors;
a programmable logic controller (PLC); and
a refrigerant reclaim tank,
wherein the PLC senses whether the refrigerant compressor is running, and when the refrigerant compressor is running, measures readings from the plurality of temperature sensors and the plurality of pressure sensors, converts pressure from the one of the plurality of pressure sensors located at an outlet of the refrigerant compressor to a high-side temperature, stores a difference between the high-side temperature and a temperature at the temperature sensor on the input side of a condenser coil (ΔTX) and a difference between the high-side temperature and a temperature on the output side on of the condenser coil (ΔTY),
wherein when ΔTX>ΔTY refrigerant is added and when ΔTY>ΔTX refrigerant is removed.
