Embodiments of the invention provide a high density liquid cooling system and various monitoring and control methods. Some methods include calculating a heat transfer efficiency of a heat exchanger based on a temperature difference and calculating a total heat rejection value based on the heat transfer efficiency. Some methods include increasing a secondary flow rate in a secondary coolant loop as a maximum allowable pressure is approached to extend an operating time period and avoid thermal shut down of the high density liquid cooling system.

Controlling high density liquid cooling system to liquid cool components

Embodiments of the disclosure provide an encapsulated compressor overload, an encapsulated compressor relay start, an encapsulated head pressure control switch and a wiring diagram for a circuit for air conditioning units which prevent gases from being ignited by means of encapsulating sparking components, use of solid-state switching devices, and/or wiring circuits in such a way that open contacts do not contain enough energy to produce a spark capable of igniting the atmosphere.
