Research Institution
A system to provide either continuous 15 kW cooling at -15 C or 100 kW cooling at 20 C is described that is very simple in terms of using only light weight micro channel heat exchangers, two constant speeed pumps (one of which is working at any moment) and some control valves. The system does not utilize a refrigerant, nor a power-consuming compressor, and the need for thermal capacitance such as typically provided by a phase changer material is minimal. Ethylene glycol-water mixtures (60-40) is used in both loops. It is responsive, simple, compact, and very lightweight. The low thermal inertia of Mezzo''''''''''''''''s heat exchangers makes it possible for units to switch operation from one condition (15 kW load at -15 C) to another operating condition (100 kW load at 20 C) very quickly, minimizing the need for a "thermal filter" to maintain tight temperature control.
