Abstract: PURPOSE: To obtain energy saving effect by stopping the operation of an oil cooler when the temperature of a compressor is low. CONSTITUTION: The delivery route 2 of refrigerant from a compressor 1 is branched into first and second delivery routes 15, 16 while the first delivery route 15 is connected to an oil cooler 6 and the oil cooler 6 is connected to a main condenser 7. The second delivery route 16 is connected to the main condenser 7 through a bypass valve without passing through the oil cooler 6. A compressor oil temperature detecting means 11 is provided and when the temperature of the compressor 1 becomes low, the discharged refrigerant from the compressor 1 is sent to the main condenser 7 through the bypass valve without passing through the oil cooler 6 by opening the bypass valve whereby the excessive reduction in the temperature of the compressor 1 is prevented and energy saving effect can be obtained.

Abstract: PURPOSE: To prevent refrigerant from being decomposed under an abnormal high temperature of the refrigerant and to perform a forced convection cooling of a compressor by a method wherein when a temperature of discharged gas is detected and this detected gas temperature keeps an abnormal temperature of the discharged gas for a specified period of time, the compressor is stopped in its operation and a blower is electrically energized and driven subsequently even after the compressor is stopped in its operation. CONSTITUTION: If a temperature of a discharging pipe of a compressor is increased and a temperature detected by a discharged gas sensing means 6 keeps a higher temperature than an abnormal temperature of the discharged gas for a specified period of time, for example, 5 seconds, the operation is transferred to a discharged gas abnormal mode. Then, a compressor 1 is turned off by a relay 11 and is stopped in its operation for a predetermined period of time. However, a fan motor 4 is electrically energized and driven as it is after elapsing a specified period of time. Then, after elapsing a specified period of time, the relay 11 is turned on by a control circuit 13, the compressor 1 is again electrically energized and driven to start a cooling operation. At this time, the fan motor 4 is subsequently electrically energized and driven. With such an arrangement as above, a recovering of the compressor 1 is rapidly carried out, an inner side of a refrigerator is cooled again to enable a foodstuff in the refrigerator to be prevented from being decayed.

Abstract: PURPOSE: To catch dust and dirt without fail, which enter a condenser, without deteriorating the radiation capability of the condenser, and improve the cooling performance and reliability by arranging an electric astatically charging type dust stick, which is approx. in parallel with tubes, on the air flow upstream side of the condenser. CONSTITUTION: A machine chamber 2 is formed at a lower rear part of a refrigerator main body 1 for which a heat insulating material is inserted between an external box and internal box, and the machine chamber 2 is constituted with an external box bottom plate 3, condenser 4 consisting of tubes and fins, blower 5 consisting of a motor 5a, blades 5b and partitioning plate 6, and mounting plate 8 on which a compressor 7 is mounted. Then, a tilted surface part is provided on the external box bottom plate 3. Then, a dust stick 15 is arranged on the upstream side of the condenser 4. The dust stick 15 is made of an electric-charging type material which is arranged approx. in parallel with tubes 4a in front of the tubes 4a, and has a base 15a and a plurality of bar form sticks 15b. By this method, air containing dust and dirt collides with the dust stick, and dust and dirt are removed, and the adhesion of dust and dirt to the condenser becomes hard to generate.
