Abstract
A device for use in a refrigeration or heat pump system. A device includes an outer casing which includes a longitudinal cylindrical shell and end plates arranged at both ends of the shell, and at least three units of the refrigeration or heat pump system arranged inside the same common outer casing, which units are selected from the group consisting of an evaporator, a superheater, an economizer, a condenser, a desuperheater, a sub-cooler and an oil cooler.
Claims18
A device configured for use in a refrigeration or heat pump system, which device comprises
- an outer casing which comprises a longitudinal cylindrical shell and end plates arranged at both ends of the shell, and
- at least a first unit, a second unit, and a third unit of the refrigeration or heat pump system arranged inside the same common outer casing, which first, second, and third units are selected from the group consisting of an evaporator, a superheater, an economizer, a condenser, a desuperheater, a sub-cooler, an oil cooler and a reservoir,
- wherein the device comprises
- (i) at least a first plate pack and a second plate pack having own inlet and outlet connections and arranged adjacent to each other inside the common outer casing for forming the first unit and the second unit of the system, and further the third unit of the system is formed to the first and/or the second plate pack by arranging a baffle plate inside a flow passage of said plate pack, or
- (ii) two separate parts of the outer casing, which are formed by arranging a first partition wall between the parts inside the outer casing, wherein the first part of the outer casing comprises at least two units of the system, which at least two units of said part are formed by
- arranging at least a first plate pack and a second plate pack adjacent to each other inside said part of the outer casing for forming the first unit and the second unit of the system, wherein said plate packs have own inlet and outlet connections, and the first plate pack and the second plate pack are separated from each other by an intermediate plate, which is arranged between the first and second units formed of adjacent plate packs, or
- arranging at least a plate pack inside said part of the outer casing, wherein at least a baffle plate is arranged inside a flow passage of the plate pack for forming the at least two units of the system to the plate pack inside said part of the outer casing,
- and a second part of the outer casing comprises at least one unit of the system, or
- (iii) at least three separate parts of the outer casing, which are formed by arranging a first partition wall and a second partition wall between the parts inside the outer casing, and each of the parts comprises at least one unit of the system.
