Claims
- 1. A method of operating a refrigeration system which achieves and holds a predetermined set point temperature in a conditioned space via cooling and heating cycles, with the refrigeration system including a refrigerant compressor which includes a compressor oil cooler having an inlet and an outlet, and a compressor prime mover which includes an engine having liquid engine coolant and an engine coolant flow circuit which includes a thermostat and a radiator, characterized by the steps of:
- providing a thermostat of the by-pass type, having first and second inlets and an outlet,
- and connecting the outlet of the thermostat to the inlet of the compressor oil cooler, providing a constant flow of engine coolant to the oil cooler regardless of the relative flow rates into the first and second inputs.
- 2. A refrigeration system which achieves and holds a predetermined set point temperature in a conditioned space via cooling and heating cycles, with the refrigeration system including a refrigerant compressor which includes a compressor oil cooler having an inlet and an outlet for connection to a cooling circuit, and a compressor prime mover which includes an engine having liquid engine coolant and an engine coolant flow circuit which includes a thermostat and a radiator, characterized by:
- said thermostat being of the by-pass type, having first and second inlets and an outlet,
- and including means connecting the outlet of the thermostat to the inlet of the compressor oil cooler, providing a constant flow of engine coolant to the oil cooler regardless of the relative flow rates into the first and second inputs.
