Embodiment Construction

[0034] figure 1 One embodiment of a heating, ventilation, and air conditioning (HVAC) system 10 in a building 12 is shown in a typical commercial setting. The system 10 may include a vapor compression system 14 that can provide cooling liquid to cool the building 12 and a cooling tower 13 that provides a process fluid to the compression system 14 through a conduit 15. The system 10 may also include a boiler 16 that provides heated liquid to heat the building 12 and an air distribution system that circulates air through the building 12. The air distribution system may include a return air duct 18, an air supply duct 20 and an air handler 22. The air handler 22 may include a heat exchanger connected to the boiler 16 and the vapor compression system 14 through a conduit 24. The heat exchanger in the air handler 22 may receive the heated liquid from the boiler 16 and / or the cooled liquid from the vapor compression system 14, depending on the operating mode of the system 10. In on...

Abstract

A condenser includes a shell with a vapor refrigerant inlet, a first tube bundle, and a liquid refrigerant outlet. A second tube bundle is positioned in the subcooler section. The subcooler component has a central channel and at least two outer channels and is fitted to the housing.

Description

[0001] Cross-reference of related applications [0002] This application is a partial continuation application of US application No. 12 / 809,839 entitled "HEAT EXCHANGER" with the filing date or 371(c) dated June 21, 2010, which was filed on January 2, 2009 The national phase of the international application No. PCT / US2009 / 030027 with the title "HEAT EXCHANGER", which requires the United States provisional application No. 61 / 018,539 filed on January 2, 2008 and titled "CONDENSER SUBCOOLER" All these applications are incorporated into this application by reference. Background technique [0003] This application relates generally to heat exchangers in vapor compression systems. The present application relates more specifically to condensers for vapor compression systems with subcooler components. [0004] In some condensers, the tube bundle(s) can be positioned in the housing or shell and used to circulate a fluid capable of exchanging heat with refrigerant vapor entering the housing....
