Refrigerant evaporator suitable for remote mounting

Claim 1

A refrigerant evaporator assembly suitable for remote mounting to a ceiling of a trailer compartment having a served space to be conditioned, comprising: an evaporator module having a metallic base member, an evaporator coil, a refrigerant circuit having refrigeration components, and an electrical circuit having electrical components, said base member having first and second axial ends, first and second sides, and upper and lower surfaces, said evaporator coil extending substantially from one axial end of the base to the other, and having headers fixed to the upper surface of said base member which orient the evaporator coil towards a predetermined side of the base member as it extends upwardly from a location on the base member intermediate the first and second sides, a cover module including a metallic cover member having first and second axial ends which define an inverted U-shaped configuration having a bight portion and first and second depending leg portions, said cover module being fixed to said evaporator module, such that said depending leg portions of the metallic cover member are respectively located at the first and second axial ends of said base member, said evaporator and cover modules defining a substantially tubular housing having first and second open ends, wherein the first open end is defined by the first side of the base member and by the first side of the metallic cover member, and the second open end is defined by the second side of the base member and the second side of the metallic cover member, a grille removably fixed to the first open end of the tubular housing, and an evaporator blower module removably fixed to the second open end of said tubular housing, whereby the blower module and the refrigeration circuit and electrical circuit components mounted within the tubular housing may be serviced by removal of the blower module, and the grille may be removed for servicing electrical circuit components mounted within the tubular housing, without removing the tubular housing from a ceiling of a trailer compartment.
