Web30 de sept. de 2024 · The main difference that separates heat exchangers and chillers from each other is their design. Heat exchangers, as opposed to chiller systems, don’t have a refrigeration unit for cooling their circulating chiller fluid. Instead, they use direct fluid heat transfer to achieve the desired temperature regulation. Webchiller has a higher COP compared to a single stage chiller, a two stage chiller also requires a generator temperature about 150°F higher than a single stage chiller. Where high temperature heat sources are available, either design can be used. While a two stage heat recovery absorption chiller can produce more capacity toyota rav4 on motability
