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.

Abstract: PURPOSE:To reduce the noise accurately and economically by outputting previously processed sound-wave signals from a wave pattern generator according to detected signals of a sound receiver to operate a sounding device. CONSTITUTION:Noise level in a machine room 12 of a compressor 13 has properties of increasing in a band less than about 600Hz and a band of 1-5KHz, and in the noises corresponding to these bands, the noise of high frequency is reduced by a machine room cover 1 7 and a partition plate 18, etc., due to sound transmission loss, and can be deadened by a sound absorbing member provided in the machine room 12. Standing waves of the noise below target frequency have an effect only by the mode of cross direction, and are regarded as one- dimensional plane traveling waves. Therefore, this noise is detected by a microphone 19, and sound-wave signals previously made by the noise reduction principle of active control according to this signal pattern from a wave pattern generator 20 to activate a speaker 21 and to interfere in the target frequency noise, resulting in reducing the noise accurately without using an expensive computing unit.

Abstract: PURPOSE:To improve the comforableness of warm temperature environment for occupants in an office area by installing a first diffuser and a second blowout port which are communicating with a ventilation duct communicating with a conditioned air supply source formed on a vertical wall, and lowering the blowout air temperature from the second diffuser provided above the first diffuser than the blowout air temperature from the first air diffuser. CONSTITUTION:During cooling time, diffusers 11 and 12 for cooling service are opened while blowout ports 13 and 14 for heating service are closed so that a heater 10 may be controlled. The temperature of a conditioned air flowing through a second ventilation air duct 9 is set so that it may be higher that the temperature of airconditioned air flowing through a second ventilation air duct 3. Under this setting, the air present in the conditioned air duct 2 are blown out from the second diffuser 11 and the first diffuser 12 for cooling service by way of the ventilation air duct 3 and the second ventilation air duct 9 respectively. However, the blowout air CH from the first diffuser has a temperature higher than the blowout air CC discharged from the second diffuser 11, and produces buoyancy, which serves to prevent the blowout air CC from descending so that the discharged air may not fall downward have cool air hang over the entire entire area instead. Therefore, the cooled air will not come to occupants directly so that the occupants may not feel the draft, but enjoy comfortable cooling environment.

Abstract: PROBLEM TO BE SOLVED: To reduce a refrigerant quantity, and to enhance efficiency in a cooling cycle using a combustible refrigerant. SOLUTION: A closed loop is formed of a compressor 12, a condenser 2, a passage control means 13, a first pressure reducing means 7, and a first evaporator 3. A second pressure reducing means 8 and a second evaporator 5 are connected so as to become parallel to the first pressure reducing means 7 and the first evaporator 3. Since cooling is performed by alternately switching the two evaporators 3 and 5 by the cooling cycle for arranging the passage control means 13 on the inlet side of the first pressure reducing means V and the second pressure reducing means 8, pipe capacity of a cooling system and the refrigerant quantity can be reduced more than a cooling system for performing cooling by one evaporator and a cooling system for performing cooling by flowing the refrigerant in parallel to a plurality of evaporators.

Abstract: PROBLEM TO BE SOLVED: To reduce a refrigerant quantity, and to enhance efficiency in a cooling cycle using a combustible refrigerant. SOLUTION: A closed loop is formed of a capacity variable compressor 12, a condenser 2, a passage control means 13, a first pressure reducing means 7, and a first evaporator 3. A second pressure reducing means 8 and a second evaporator 5 are connected so as to become parallel to the first pressure reducing means 7 and the first evaporator 5. Since cooling capacity is adjusted by compressor capacity according to a load by performing cooling by alternately switching the two evaporators 3 and 5 by the cooling cycle for arranging the passage control means 13 on the inlet side of the first pressure reducing means 7 and the second pressure reducing means 8, pipe capacity of a cooling system and the refrigerant quantity can be reduced more than a cooling system for performing cooling by one evaporator and a cooling system for performing cooling by flowing the refrigerant in parallel to a plurality of evaporators.

Abstract: PROBLEM TO BE SOLVED: To provide a liquid simulation device which performs grid creation and real calculation in a short time, obtains an analytical result with high accuracy and deals even with a viscosity problem. SOLUTION: An I/F part 2 converts object external form data (DXF format, etc.), such as triangular mesh that is formed on the object external form into a prescribed data format such as UCD(unstructured cell data) format by using a three-dimensional CAD 1, and an analytical data creating part 3 automatically creates the so-called Cartesian lattice whose lattice width gradually becomes small in optional intervals as it approaches the object in space in the range of a prescribed analytical object by using the object external form data. An analyzing part 4 performs numeric analysis by means of a local collocation procedure at a lattice point within the prescribed range of an object neighborhood and performs numeric analysis by means of the so-celled Cartesian lattice local collocation procedure that uses a difference method at a lattice point except it by using data of the lattice and other analytical data. An analytical result is made visible by a display part 5.

Abstract: PURPOSE:To improve the efficiency of the heating and achieve evenness in the temperature distribution in the room by providing a means of switching over the air outlet whereby a switchover is made between a lower outlet and an upper outlet according as a operation mode is turned to heating or cooling and also by providing at the lower outlet means of altering the direction of the ejected air whereby the air ejected can be sent in any direction as desired. CONSTITUTION:In heating, the indoor air sucked in through an inlet 36 undergoes heating by a heat exchanger 27 and then in sent into an air duct 33 by a blower 28; for the heating, the vane of a means-of-switching-over-the-air-outlet 30 is driven upward so that warm air flows downward through the air duct 33, through a lower outlet 32 into a space 39 under the room, through the space 39 and into the room through a vent 40; the warm air heats the flooring 38 of a double-floor structure evenly throughout from under as it flows thereunder, and heats the room 24 as it flows therein and is sucked into the inlet 36. In cooling, the vane of the means-of- switching-over-the-air-outlet 30 is driven downward so that cool air flows upward through the air duct 33, flows out through an upper outlet 31, and after impinging against the ceiling 23, cools the room 24 as it spreads downward therefrom and is subsequently sucked into the inlet 36.
