Abstract: PROBLEM TO BE SOLVED: To enable restricting of a temperature rise in an inverter device by performing a high-speed operation of a fan motor for a compressor with a second inverter when a first inverter reaches a high temperature and is determined to exceed a specified temperature by a first comparator means. SOLUTION: When a compressor is operated in an operation pattern, the temperature (t) of an inverter device 4 as detected by an inverter temperature detection means 7 is compared with a first set value (T1), an allowable temperature value with a little allowance, of the inverter device 4 by a first comparator means 8.

Abstract: PURPOSE: To enable the liquid compression diagnosis of a compressor without needing any prototype by envelope detection of a piezo-electric signal from a piezo-electric element mounted on the external appearance part of the compressor. CONSTITUTION: A sensor 2 consisting of a piezo-electric element mounted on a compressor 1 detects a signal caused by the liquid compression of the compressor 1, and the detected signal is subjected to envelope detection by an envelope detection apparatus 3 and indicated on an output apparatus 4. Then, the outputted signal has the same wave form as the actual pressure waveform in timing and form of the peak waveform. Thus, a liquid compression phenomenon can be judged from a threshold line corresponding to the highest pressure line in the normal running and the liquid compression can be confirmed when a peak value of the signal peak waveform exceeds the threshold line.

Abstract: PROBLEM TO BE SOLVED: To hold down a temperature rise of a cold storage room and a refrigeration room during the stop of a compressor to the minimum. SOLUTION: On detecting that the temperature of the cold storage room 9 and the temperature of the refrigerating room 10 are equal to or lower than the set temperature, the compressor is stopped, and a three-way valve is totally closed. The totally closed state is continued until the next start of the compressor 1. During the stop of the compressor 1, a high temperature and high pressure refrigerant does not flow into the cooling devices of the cold storage room 9 and the refrigeration room 10, so that the temperature rise in each room can be held down to the minimum.

Abstract: PROBLEM TO BE SOLVED: To prevent separation of an air flow, and restrict turbulence in a confluent flow in the condition of high air way resistance wherein speed increase of an axially discharged air flow from a pressure surface side trailing edge of a blade generates a large circulation vortex at a suction side leading part of the blade, separates an air flow along a negative pressure surface by a suction, turbulent air flow, enlarge turbulence when the pressure surface side air flow is confluent with the negative pressure surface side one at the trailing edge, deteriorate blowing performance of an impeller, and increase generated turbulence sound. SOLUTION: A recessed part (air flow direction changing means) 8b extended to be close to the trailing edge of the blade 8 at one end is provided on the side of a pressure surface 5 of the blade 8, and a protruded part 8a (air flow adhering means) is provided at a trailing edge part of the blade 8. An air flow of a large radial speed component passing the impeller 9 is converted into an axial direction by the recessed part 8b to increase air flow speed in the axial direction, and separation of the negative surface side air flow is restricted by the protruded part 8a. Turbulence when the air flow on the negative surface side is confluent with the air flow on the pressure surface side can thus be restricted, thereby deterioration of blowing performance of the impeller and increase of blowing noise can be restricted.

Abstract: PROBLEM TO BE SOLVED: To provide a manifold incorporating a thermoelectric module in which heat exchanging efficiency is enhanced by regulating the flow rate of heat carrier. SOLUTION: In a manifold 1 incorporating a thermoelectric module 7, heat exchanging efficiency is enhanced by differentiating the flow rate of heat carrier on the cooling side from the flow rate of heat carrier on the heating side. In order to lower the temperature of heat carrier on the cooling side, channel resistance in the manifold 1 is designed such that the flow rate of heat carrier on the heating side is lower than the flow rate of heat carrier on the cooling side. When pump components, e.g. impellers 5, 6 constituting a volute pump, are incorporated, heat carrier delivery capacity of the pump components is designed.

Abstract: PROBLEM TO BE SOLVED: To provide a cooler utilizing Peltier effect which can operate with no trouble even under inclining state, and a method for increasing the chance of contact between a heat carrier and the heat transfer surface of a thermoelectric module by removing bubbles in the piping. SOLUTION: In an air purge chamber, pipes (tubular members) are employed at both the heat carrier inlet 48 and heat carrier outlet 49 extending into a container 47. The pipes enter the container 47 from the center on the bottom face thereof. The pipe constituting the heat carrier inlet 48 extends to the vicinity of the center of gravity of the container 47 and opens thereat.

Abstract: PROBLEM TO BE SOLVED: To prevent a user from feeling uncomfortable during the use of a refrigerator by reducing the generation of vibration of a refrigerator and prevent the occurrence of breakage of a piping since vibration is transmitted to a refrigerator body due to resonance of a piping, a user feels an uncomfortable feeling or a problem on breakage of a piping due to resonance of the piping arises. SOLUTION: An operation control device for a refrigerator comprises a refrigerator back part vibration detecting means 12 to detect vibration of the back part of a refrigerator; a comparing circuit 13 to compare an input value from the refrigerator back part vibration detecting means 12 and a threshold with each other; and an inverter circuit output frequency correction circuit 14 to correct an inverter circuit output frequency outputted from an inverter circuit output deciding circuit 5 by means of the output of the comparing circuit 13. This constitution reduces the generation of vibration of the refrigerator and prevents a user from feeling uncomfortable during the use of the refrigerator.

Abstract: PROBLEM TO BE SOLVED: To curb effervescence of liquid refrigerant at the outlet header of an evaporator and make a sudden liquid back less possible to occur by a method wherein for a preliminarily set time at the start a minimum value is set for the number of revolutions of the compressor and subsequently the operation is controlled at an optimal number of revolutions for the control of the storage temperature. SOLUTION: A freeze chamber temperature differential-calculating means 24 calculates the temperature differential between the freeze chamber temperature detected by a freeze chamber temperature detective means 21 and the set temperature for the freeze chamber 8 detected by a freeze chamber temperature-setting means 23 and from the temperature differential a revolution speed-calculating means 25 decides the revolution speed of the compressor 17 and an inverter circuit 26 operates the compressor 17 at the decided number of revolutions. The compressor is operated at the minimum revolution speed according to a minimum revolution speed command- transmitting means 43, at a preset time a timer 42 stops transmitting a revolution speed command, and the number of revolutions of the compressor 17, decided by a revolution speed-calculating means 25, is transmitted. This method makes a sudden liquid back less possible to occur.
