Heat Pump Non-Reversing Valve Arrangement

摘要

A heat pump system that is operable in heating and cooling modes and which maintains the direction of fluid flows through a primary heat exchanger during heating and cooling operations such that the respective fluids are directed in counter flow thermal directions during both heating and cooling operations.

1. A heat pump system comprising:
a primary heat exchanger having a first fluid path associated with a first fluid and a second fluid path, associated with a second fluid, the first fluid path and the second fluid, path allowing a thermal exchange between the first fluid and the second fluid; an evaporator fluidly connected to the second fluid path; a compressor fluidly connected to the second fluid path; a secondary heat exchanger fluidly connected to the compressor, the secondary heat exchanger being fluidly associated with an air path and the second fluid path; and a valve arrangement associated with the second fluid path and being operable to maintain a common direction of flow of the second fluid during heating and cooling operations associated with the air path.
