Web7 Jan 2010 · You can measure superheat and subcooling on a VRV but it depends on what information you need. You're unlikely to see steady sub cooling until the VRV is running at its maximum ( TEST mode as Nike says ) and has been running long enough for all the expansion devices to settle. Superheating is analogous to subcooling in an operative way, and both processes can be coupled using an internal heat exchanger. Subcooling here serves itself from the superheating and vice versa, allowing heat to flow from the refrigerant at a higher pressure (liquid), to the one with lower pressure (gas See more The term subcooling (also called undercooling) refers to a liquid existing at a temperature below its normal boiling point. For example, water boils at 373 K; at room temperature (293 K) liquid water is termed "subcooled". … See more Expansion valve operation and compressor safety Subcooling is normally used so that when the refrigerant reaches the thermostatic expansion valve, all … See more Subcooling phenomena is intimately related to efficiency in refrigeration systems. This has led to a lot of research on the field. Most of the interest is placed in the fact that some … See more • Physics portal • Heat transfer • Economizer • Evaporation See more The subcooling process can happen in many different ways; therefore, it is possible to distinguish between the different parts in which the process takes places. Normally, … See more In a common refrigeration system, the refrigerant undergoes phase changes from gas to liquid and from liquid back to gas. This enables to consider and discuss superheating and … See more
