733,104. Refrigerating; heat pumps. RADIATION, Ltd. April 7, 1954 [April 7, 1953], No. 9348/53. Class 29. A refrigerating machine or heat pump comprises a rotor having passages in which a non-condensing gaseous medium, e.g. air, circulates so that it takes up heat from a low ...
There are several methods of conveying heat away from one place and delivering it at another. One is absorption of ammonia gas by dissolving in water at one pressure then coming out of solution at another pressure. This can be carried out entirely by heat, using an ingenious subsidiary ...
27 – Refrigerators and heat pumpsMAGNESIUMHYDROGEN STORAGE ALLOYELECTRODESSECONDARY BATTERIESA refrigerator comprises a lot of hollowed projections provided on the bottom of a reservoir and an auxiliary condenser secured to the top of the hollowed projections by supporting pieces in which one end ...
There is an increasing need for small-scale heat-powered refrigerators and heat pumps designed specifically for use in the light commercial sector. Such devices will provide an economic use of fossil fuels and reductions in CO 2 emissions, along with a potential for using environmentally friendlier...
The regulator is a refrigerant regulator intended for heatpumps and refrigerators. It has a built-in receiver, which automatically absorbs redundant refrigerant. It is a hermetic closed device without removable parts. It is robust and th... WJ Stokes - US 被引量: 92发表: 2001年 The maximum ...
Examples of heat pumps: Refrigerators, air-conditioners. Schematic of a refrigerator Refrigerators and aircons use fluorinated hydrocarbons such as Freon-12, Freon-22, etc, which can be compressed to a liquid by mechanical work. The liquid is pumped into the cold reservoir to be kept cool and...
The above chosen criteria for the performance optimization of refrigerators and heat pumps are not quite sufficient. This is because, in these studies, one of the criteria is chosen as an objective function while taking the rest as constraints. The coefficient of performance affects the energy ...
Difference between Heat Pumps and Refrigerators Difference between a Heat Pump and an Air Conditioner The operation of the heat pump and the other types of pumps available are bound to be a bit confusing. If you need a primer, the operation of other types of pumps are provided here for refe...
In thermoacoustic heat pumps and refrigerators, acoustic power is used to pump heat from a low-temperature source to a high-temperature sink. This review... G.W - 《J.acoust.soc.am》 被引量: 612发表: 1988年 Thermoacoustic engines and refrigerators We ordinarily think of a sound wave in ...
Air conditioners operate on the same principle as refrigerators. Consider an air conditioner that has 7.00 kg of refrigerant flowing through its circuit each cycle. The refrigerant enters the evaporator coils in phase equilibrium, with 54.0% of its mass as liquid and the rest as vapor. It flows...
