coolant

[′kül·ənt]
(materials)
A cutting fluid for machine operations, which keeps the tool cool to prevent reduction in hardness and resistance to abrasion, and prevents distortion of the work.
A substance, ordinarily fluid, used for cooling any part of a reactor in which heat is generated.
In general, any cooling agent, usually a fluid.

They mainly include; (1) magnetic field intensity; (2) type, shape and size of magneto-caloric material; (3) porosity of magneto-caloric material; (4) type of heat transfer fluid; (5) mass flow rate of heat transfer fluid shown by utilization factor (ph); (6) operating frequency of the magnetic cycle.
The performance of the heat pumps connected to the system is based on the temperature of the heat transfer fluid delivered to the heat pumps.
In this study, the heat transfer fluid in the shelf utilized ethylene glycol solution, with a concentration ratio of 50%.
While there is some guidance in the ASHRAE Handbook chapters on geothermal energy and water treatment, (1) there is little detailed information to assist the engineer with the proper selection of aboveground piping system materials and the circulating heat transfer fluids. In some cases, this can be attributed to the varying standards governing local, state and federal GHP installations.
announced today that it will be supplying Therminol VP-1 synthetic heat transfer fluid to a new 470 MW hybrid solar plant in Ain-Ben-Mathar, Morocco and a 170 MW hybrid solar plant in Hassi R'Mel, Algeria.
For unpressurized and low-pressure heat transfer systems, diaryl alkyl heat transfer fluids, such as Dowtherm RP Fluid, offer greater thermal stability and cleaner operation than fluids based on partially hydrogenated terphenyl or dibenzyl toluene chemistry.
The use of a liquid heat transfer fluid suggests that these heat exchangers will have size and performance characteristics that are comparable to conventional evaporators and condensers.
It is an effective heat transfer fluid especially designed to function in a wide range of temperatures from extreme heat of up to 280[degrees]F (140[degrees]C) and down to sub-freezing cold of -60[degrees]F (-50[degrees]C).
A closed loop active solar water heater is made up of collectors, heat transfer fluid, circulating pump, heat exchanger, and a storage tank.
introduces its new MultiTherm IG-4 Heat Transfer Fluid. Replacing MultiTherm's IG-2 fluid, the MultiTherm IG-4 offers users a safe, durable and economical heat transfer fluid.
Heat transfer fluid maintenance and analysis are essential operations that need to be conducted periodically.
On the working of the CSP, Badran said: "It uses parabolic mirrors to reflect and magnify heat from the sun onto a closed circulating loop containing Dowtherm A heat transfer fluid. The fluid collects the heat energy and transports it to a power station where it is used to produce steam, which drives turbines to generate electricity." "When used instead of fossil fuel generation plants, CSP facilities offer improved air quality and can help many nations to address off-set goals for carbon emission produced by existing fossil fuel power plants," said Badran.
