Comparative Study of Refrigerations Systems for Ice Rinks

Option A5 shows a high heating COP at 21.5. Reciprocating compressors offer the potential of more heat recovery for hot water heating due to a high gas discharge temperature. Option C2 shows a high heating COP of 19.8. This system does not use circulating pumps for heat recovery and the only other expense is for auxiliary water heating.

Dec 09, 2019 · Direct and indirect heating represent the two types of open vented hot water systems: Direct heating – in this case the water is heated directly from the heat source using a boiler or via an immersion heater. Indirect heating – in this type of hot water system, the central heating and the hot water are detached. The water is heated using a

Boiling water reactor - Wikipedia

A boiling water reactor (BWR) is a type of light water nuclear reactor used for the generation of electrical power. It is the second most common type of electricity-generating nuclear reactor after the pressurized water reactor (PWR), which is also a type of light water nuclear reactor. The main difference between a BWR and PWR is that in a BWR, the reactor core heats water, which turns to

The gas had to be compressed so that it could be condensed at these higher temperatures, using free cooling from water or air. The refrigerant is now ready to enter the evaporator to be used again. It passes through an expansion valve to enter into the region of lower pressure, which causes it to boil and absorb more heat from the load.
