摘要： PROBLEM TO BE SOLVED: To prevent erroneous detection indicating the occurrence of earthquake even if slight shock is applied depending on operation situation of equipment and to prevent combustion from stopping while detecting earthquake and restarting of combustion to improve durability of the equipment.
SOLUTION: When an earthquake detection signal continues for a fixed period of time, judging from operation situation of an earthquake detection device, an operation condition is held as it is during monitoring time set in advance, and then, if the earthquake detection signal continues for a fixed period of time after the monitoring time elapses, it is determined that earthquake is detected. At this time, if a combustion part burns, combustion is stopped. If the combustion part does not burn, combustion is not started for the restart of operation.

摘要： PROBLEM TO BE SOLVED: To reduce electric input during heating operation non-combustion in the control device of an air conditioner having a refrigerant-heating device. SOLUTION: By setting the decrease rate of frequency in increase/decrease control during heating operation non-combustion larger than that of frequency in the increase/decrease control of a compressor operation frequency during heating operation combustion, deceleration can be made to a specific frequency quickly when the compressor is to be decelerated during heating operation non-combustion, thus reducing electric input during heating operation non- combustion.

摘要： PROBLEM TO BE SOLVED: To provide an air conditioner which can distribute the capacity as demanded even when a large difference is found in the demanded capacity of room units by enabling adaptation to the demands of various operation modes of the room units. SOLUTION: There are arranged a refrigeration cycle 13 in which a compressor 1, a four-way valve 4, an outdoor heat exchanger 2, a reverse support valve 5, a throttle device 6, a room heat exchanger 8, a two-way valve 7 and a heat exchanger 10 for heating a refrigerant are connected and a fluid cycle 14 in which the heat exchanger 10 for heating the refrigerant, a refrigerant circulation device 11 and a heat radiator are connected. This enables the cooling operation and the heating operation simultaneously or the heating operation and the cooling operation to be individually suited to a plurality of locations in a room. It is also arranged to allow the altering of the circulation of a fluid with the circulation device 11, thereby changing a capacity distribution ratio between the side of the refrigeration cycle 13 and the side of the fluid cycle 14.

摘要： PROBLEM TO BE SOLVED: To optimize an injection speed of premixed gas and improve the stability of the whole of flame by a method wherein a partitioning plate is arranged at the proper place of an inner passage unit of the combustion unit of premixed gas of fuel and air or a laminated flame port, formed by laminating a plurality of plates, to permit the flow rate regulation of the premixed gas. SOLUTION: A partitioning plate 15, arranged in the upper part of inner space of a burner head 13, is provided with a plurality of premixed gas flow passages to reduce the flow rate 12a of premixed gas through the upper part of laminated flame ports and reduce the injection speed of the same gas through the upper part of laminated flame ports. The premixed gas 12, supplied to the burner head 13, is injected through the laminated flame ports 13a and is ignited by a proper ignition means to burn the same gas. In this case, flame in the lower part of the laminated flame ports 13a is retained by a ring 14, arranged at the outer peripheral part, whereby the stability of combustion is increased. On the other hand, the flow rate of premixed gas 12a in the upper part of the laminated flame ports 13a is limited by the partitioning plate 15 to slow down the injecting speed of the premixed gas 12a, injected through the laminated flame ports 13a, whereby flame retaining property is improved.

摘要： PURPOSE:To prevent a large amount of soot and carbon monoxide from being generated, by stopping combustion in the case of such a state that the number of revolutions of a burner motor is small and that combustion air cannot be sufficiently fed. CONSTITUTION:When a burner motor 5 revolves only in the number of revolutions as small as to be deemed inoperative, or it does not revolve at all, an inoperative detecting unit 8 decides that it is disabled, and outputs an operation stopping instruction to a load drive controlling unit 3. If the number of revolutions of the burner motor 5 does not reach a level of the abnormal number of revolutions, which is set to a higher level than that of the number of revolutions detected by the inoperative detecting unit 8, after a predetermined period of time from the starting of the drive of the burner motor 5, an abnormality judging unit 9 outputs an operation stopping instruction to the load drive controlling unit 3, whereby operation of both the burner motor 5 and a fuel feeding means 6 are stopped. Thus, a large amount of soot and carbon monoxide can be prevented from being generated and, and safety is enhanced.

摘要： PURPOSE:To increase lateral radiation heat capture range in a room cooler/ heater using a radiation sensor. CONSTITUTION:This room cooler/heater comprises a body 19, and a radiation sensor l provided at the body. The sensor 1 has a case 1a, a concave reflection mirror 7 covering an opening of the case, a sensor mounting plate 9 provided on a front surface of the mirror 7, and a thermistor 10 arranged on a focal point part of the mirror of the plate 9. The mirror 7 is formed in a parabolic state at least in its horizontal direction by increasing in a horizontal length with respect to the body 19. Accordingly, the cooler/heater can catch lateral radiation heats in a considerably wide range by the sensor 1 and hence accurately detect room heating or cooling state to comfortably cool or heat the room.
