In a refrigerant cycle system having a hot gas heater function, a valve device includes a solenoid valve for opening and closing a communication between a compressor and a condenser, a differential pressure valve opened by a pressure difference between a discharge side of the compressor and an inlet
In a refrigerant cycle system having a hot gas heater function, a valve device includes a solenoid valve for opening and closing a communication between a compressor and a condenser, a differential pressure valve opened by a pressure difference between a discharge side of the compressor and an inlet side of the condenser when the solenoid valve is closed for directly introducing gas refrigerant from the discharge side of the compressor into an evaporator, and a check valve for preventing refrigerant discharged from the compressor from flowing into the condenser when the solenoid valve is opened. In the valve device, at least the three valves are integrated by a housing member to construct an integrated member.

This method in a process based on contacting of reactants, reversible ester bond chemistry, separation of fractions with the desired latent heat properties, and recycle of those fractions that do not have the desired latent heat properties. ntrol member positioned upstream of said equipment assembly so as to substantially evenly distribute the cooling air to the equipment assembly; and communication means separated from the room and being in communication with the equipment assembly for receiving air flowing from the equipment assembly which has been heated by the equipment assembly, said communication means communicating the air heated by the equipment assembly back to the cooling apparatus for being cooled. 12. An air conditioning assembly as claimed in claim 11, which comprises at least one duct interconnecting the equipment assembly to the communication means for communicating air heated by the cooling equipment to the cooling assembly. 13. The air conditioning assembly as claimed in claim 11, which comprises at least one fan for communicating the heated air to the plenum. 14. An air conditioning assembly as claimed in claim 11, wherein the cooling apparatus cools the cooling air to a temperature of substantially 55° F. 15. The air conditioning assembly as claimed in claim 11, wherein the equipment apparatus heats the air blowing into the plenum to a temperature of substantially 95° F. 16. The air conditioning assembly according to claim 11, wherein a temperature differential between the air supplied to the equipment apparatus and the air introduced into the communication means from the equipment assembly is substantially 40° F. 17. The method as claimed in claim 1, which comprises positioning the equipment assembly in a cabinet and positioning the flow control member in said cabinet upstream of said equipment so as to control air flow to said equipment. 18. The cooling apparatus as claimed in claim 11, which comprises a cabinet within which the equipment assembly is located and wherein the control member is positioned so as to be spaced from a wall of the cabinet so as to form a space within which the cooling air is communicated prior to being received by the equipment assembly. 19. An air conditioning assembly as claimed in claim 11, wherein the equipment assembly comprises at least one computer processing unit. 20. The apparatus according to claim 11, wherein said communication means comprises one of a plenum, a duct and a room. 21. The cooling method claimed in claim 1, wherein the communication of air from the equipment comprises communicating the air into one of a plenum, a duct and a room. 22. The cooling method according to claim 1, which comprises positioning said air passageway in proximity with the floor of a room. 23. The cooling method claimed in claim 1, wherein the step of supply cooling air comprises supplying cooling air into a passageway formed below a floor on which the equipment assembly is positioned. 24. The cooling apparatus according to claim 11, wherein said air passageway is positioned in proximity with the floor. 25. The cooling apparatus according to claim 11, wherein said air passageway is positioned with a plenum formed between the floor and a base floor. 26. An air conditioning assembly, which comprises: cooling means in communication with an air passageway for introducing cooling air into said air passageway; an equipment assembly positionable on a floor of a room, the equipment having an opening in communication with said air passageway for receiving the cooling air from the cooling means; a flow control member positionable upstream of said equipment assembly so as to substantially evenly distribute the cooling air to the equipment assembly; and communication means in communication with the equipment assembly and separated from the room for receiving air flowing from the equipment assembly which has been heated by the equipment assembly, said communication means communicating the air heated by the equipment assembly back to the cooling apparatus for being cooled. 27.
