www.nrel.govcooled condenser, and a chiller. The condenser and the chiller serve the same purpose as the condenser and the evaporator in a traditional refrigeration loop. Instead of exchanging heat with air, these heat exchangers exchange heat with circulating coolant and therefore act as sources of hot and cold coolant streams.

terpconnect.umd.eduJun 02, 2010 · and partially condensed in a water-cooled heat exchanger whose heat duty is 102 MW. The stream is separated in a tank operating at 106.6 bar and 38 °C. The total pressure drop around the gas loop (heat exchangers and reactor) is 3.4 bar. Most of the vapor stream is compressed back up to 110 bar and recycled. The recycle compressor work is 1.10 ...

booksite.elsevier.comheat. Section 3.3 introduces other heat recovery approaches. When it is economically attractive, heating and cooling are accomplished by heat recovery between process streams. The design of a network of heat exchangers for heat recovery can be a complex task if there are many hot and cold streams in a process. Pinch analysis, introduced in

www.flightsystems.comIn the cooling mode, chilled water absorbs heat via the coils and fan in the compart-ment’s air handling unit. The central unit consists of a compressor, two heat exchangers and a circulating pump. The central unit functions as a reverse cycle heat pump so it can provide either heating or cooling by simply reversing the flow of refrigerant ...
