摘要： PROBLEM TO BE SOLVED: To provide a housing cooling system capable of being space-saved, reducing the number of units to be installed and decreasing a time required for discussing a unit installing position. SOLUTION: The housing cooling system 1 cools in a housing 3 by a main cooler 10 having a forcibly circulating refrigerant circuit 16 and an auxiliary cooler 9 having a natural circulation refrigerant circuit 15. In this system 1, the auxiliary cooler 9 executes a ventilating operation for sucking atmosphere into the housing 3 by an indoor side fan 25, and exhausting the indoor atmosphere out of the housing 3 by an outdoor side fan 26 in addition to an ordinary cooling operation using the refrigerant circuit 15.

摘要： PROBLEM TO BE SOLVED: To prevent a sudden change in an indoor temperature when changing a refrigerant passage due to a change in a load by operating both of a first and a second motor operated valves and sending a refrigerant from a compressor in parallel to a first and a second condensers in the case when a load temperature is within a target temperature range. SOLUTION: A first bypass piping 19 having a first motor operated valve 11 connected to a piping by bypassing a four-way valve 2b from an outlet of a compressor 1 to an inlet of a first condenser 4, and a second bypass piping 20 also having a second motor operated valve 12 are provided. A temperature detector 34 for detecting a load temperature is installed on an air conditioning load and a pressure detector 33 for detecting a refrigerant pressure is formed on an outlet side piping. Also, a temperature controller 35 is provided for controlling the load temperature by controlling condition of a refrigerant flowing through the first condenser 4, a second condenser 8, and an evaporator 7. The temperature controller 35 is provided with a function to open both the first and second motor operated valves 11 and 12 to send the refrigerant from the compressor 1 in parallel.

摘要： A condenser (2), an electronic expansion valve (5), an evaporator (6), and a motorized suction throttle valve (8) are connected in series with a compressor. When a capacity is increased, the electronic expansion valve (5) is controlled to be in a throttling direction and the motorized suction throttle valve (8) is controlled to be in an unthrottling direction in association with the control of the electronic expansion valve (5), and when a capacity is decreased, the electronic expansion valve (5) is controlled to be in an unthrottling direction and the motorized suction throttle valve (8) is controlled to be in a throttling direction in association with the control of the electronic expansion valve (5). While a capacity control of a compressor by a throttle control is been carried out, such associated control is made between the electronic expansion valve (5) and the motorized suction throttle valve (8), realizing a fine temperature control in a refrigerating machine without hunting.

摘要： PURPOSE:To realize an exact temperature control in the storage tank of a refrigerator without hunting. CONSTITUTION:A condenser 2, electronic expansion valve 5, evaporator 6, and electromotive suction throttle valve 8 are connected in series to a compressor 1. When the capability is raised, the electronic expansion valve 5 and the electromotive suction throttle valve 8 are interlinked and controlled so as to move the former in the direction of closing and the latter in the direction of opening, and when the capability is lowered, the electronic expansion valve 5 and electromotive suction throttle valve 8 are interlinked and the former is moved in the direction of opening and the latter in the direction of closing. With this arrangement it is possible to prevent hunting by the interlinking and control of the electronic expansion valve 5 and electromotive suction throttling valve 8 as the capacity control of the compressor 1 by suction throttling system is carried out.

摘要： PURPOSE:To eliminate a heat exchanger for cooling a capillary tube by a method wherein the capillary tube is inserted into a cooling pipe, refrigerant is divided to flow on the up- stream side of the capillary tube and then the divided refrigerant is guided to a passage between the capillary tube and the cooling tube. CONSTITUTION:About half of a capillary tube 2 at its one end is inserted into a cooling pipe 13 and the other end is connected to an up steam side refrigerant passage 6. When a flow rate of refrigerant flowing into an evaporator 1 is lacking and a temperature of the refrigerant at an outlet of the evaporator 1 becomes excessively high, a temperature sensing part 9 may detect it to transmit it to an expansion valve 7 so as to increase a degree of opening of the expansion valve 7. Accordingly, an amount of refrigerant flowing into a branch passage 5 is increased, the refrigerant within the capillary tube 2 is cooled, a flash point is moved toward the outlet port of the capillary tube 2 so as to increase a total amount of circulation of the refrigerant within the tube. If a flow rate of the refrigerant flowing into the evaporator 1 is too excessive, a degree of opening of the expansion valve 7 is reduced and a total amount of circulation of the refrigerant is reduced. In addition, a part of the refrigerant passed through the expansion valve 7 may contribute cooling operation for a cooled item flowing into the evaporator 1 through the cooling pipe 13 and plate fins 11.

摘要： PURPOSE:To attempt to prevent frequent change-overs of a coolant circuit and obtain an air conditioner which is capable of continuing stable operation by controlling a change-over valve, blower, and compressor in accordance with the humidity of a room. CONSTITUTION:A change-over valve 9 is constituted with an electromagnetic valves 9a, 9b to form a second circuit 9a1 in which coolant passes only through the electromagnetic valve 9a and a first circuit 9b1 in which the coolant passes only through the electromagnetic valve 9b. A first temperature regulator 14 is set at a first predetermined temperature and a second temperature regulator 15 is set at a second predetermined temperature which is lower than the first predetermined temperature. A blast control device 16 has a temperature sensitive section 16a which detects the temperature of a U-bend section 4a of a first condenser 4 and it controls the rotational speed of a first blower 3, that is its blast according to the condensation temperature. In case of high humidity in the room, a change-over valve 9 is changed over from the first circuit 9b1 to the second circuit 9a1 when the indoor air temperature falls to the first predetermined temperature. When it falls to the second predetermined temperature, the first blower 3 which is controlled by the blast control device 16 is stopped and when the humidity of the room falls to a predetermined humidity the compressor 1 is stopped. In case the room air humidity is lower than the predetermined humidity, a compressor 1 is stopped when the room air temperature falls to the first predetermined temperature.
