Abstract:
1. A method for controlling the temperature of a cold plate comprising the steps of: compressing a refrigerant received from an evaporator of a cold plate; directing the compressed refrigerant along a first path to the cold plate, the first path configured to receive compressed refrigerant from the compressor and to supply cooled refrigerant to the evaporator of the cold plate; redirecting at least a portion of the compressed refrigerant along a second path to the cold plate, the second path configured to receive compressed refrigerant from the compressor and to supply non-cooled refrigerant to the evaporator of the cold plate; comparing a temperature reading associated with the cold plate to a predefined temperature range; and controlling the portion of the compressed refrigerant redirected along the second path responsive to the compared temperature reading such that the redirected portion is incrementally increased if the temperature reading is below the temperature range to heat the cold plate and the redirected portion is incrementally decreased if the temperature reading is above the temperature range to cool the cold plate.
