摘要： PROBLEM TO BE SOLVED: To provide a combustor with an exhaust hood which can determine the gas volume of a duct. SOLUTION: A combustor with an exhaust hood is constituted in such a way that the exhaust gas from a hot water supply apparatus and the gas taken in from the inlet port of the exhaust hood is mixed together and the mixture is led to a main duct passage as mixed exhaust air. An overflowing exhaust gas temperature detecting means 11 detects the temperature of a gas going in and out through the inlet port of the hood and an exhaust gas temperature detecting means 10 detects the temperature of the mixed exhaust gas. An exhaust gas temperature determining means 22 for the hot water supply apparatus determines the temperature of the exhaust gas from the apparatus from combustion operation parameters including the quantity of combustion heat of the apparatus and determined data on the temperature of the exhaust gas from the apparatus and a flow rate determining means 23 for the exhaust gas from the apparatus determines the flow rate of the exhaust gas from the apparatus from the parameters and the data. Then a duct gas volume determining means 24 finds the flow rate of the mixed exhaust gas led to the main duct passage from the exhaust hood as the gas volume of the duct based on the flow rate and temperature of the exhaust gas from the apparatus and the temperatures of the mixed exhaust gas and the gas and previously given duct gas volume determining data.

摘要： PROBLEM TO BE SOLVED: To prevent a fire of an exhaust duct and to improve handling operability. SOLUTION: In the combustion equipment, an exhaust side of a water heater 1 is connected to a main duct passage 3 through an exhaust hood 5, and exhaust gas of the heater 1 is exhausted to the passage 3 through the hood 5. The equipment comprises an exhaust gas temperature detecting means for detecting a temperature of an exhaust gas exhausted from the hood 5 to the passage 3, and an atmospheric temperature detecting means for detecting a temperature of the circumference of the heater 1. Thus, a threshold value temperature is variably set in an allowable variable range in response to the detected atmospheric temperature of the atmospheric temperature detecting means, and, when the detected temperature of the exhaust gas temperature detecting means exceeds the threshold value temperature, combustion of the heater 1 is stopped to prevent a fire of the duct. If the atmospheric temperature is high, a problem of wrong handling operability caused by frequent stops of combustions due to a rising temperature of the exhaust gas to the passage 3 though an exhaust gas sucking force of the passage 3 is normal is prevented.

摘要： PURPOSE:To provide a duct type air conditioner in which a. operation mode is changed automatically into an air ventilation mode or a dry mode. CONSTITUTION:A circuit in which an operation is automatically changed to an air ventilation mode in response to a difference between an initial temperature and a set temperature sensed by a main controller 11 is installed within a controller 14. In the case that a humidity detected by a humidity sensor 13 fixed to an air suction port 4 indicates a value more than a specified value, and the condition is in an air ventilation mode, the controller 14 is added with a control circuit for operating preferentially to a dry mode.

摘要： PURPOSE:To make it possible to effect heating even during cooling operation and dehumidification while the temperature of the room is kept comfortable by connecting to hot-water supply circulation piping an auxiliary heat exchanger incorporated in a room unit in a setup to operate it by utilizing the supply of hot water and control its operation which can either be independent or in conjunction with a cooling/heating heat exchanger. CONSTITUTION:Chilled or hot water produced by a chilled/hot water-producing device 1 is circulated by air-conditioning circulating pipings 2, 2a and, through branch pipings 5, 5a, circulated in a cooling/ heating heat exchanger 4 in a room unit 3 in each dwelling unit to effect air conditioning; on the other hand, hot water in a hot-water supply unit 6 is used for the supply through a hot-water supply branch piping 9 from a hot-water supply circulation piping 7 and through a hot-water cock 8. An auxiliary heat exchanger 10 is incorporated in the room unit 3 and connected to the hot-water supply circulation pipings 7, 7a by auxiliary branch pipings 11, 11a in a setup to utilize the heat of hot water supplied and enable a controller 12 to operate the auxiliary heat exchanger 10 independently or in conjunction with a cooling/heating heat exchanger 4 in the room unit 3.

摘要： PURPOSE:To improve an unfavorable rising at the time of simultaneous operation for all rooms or plural rooms by a method wherein a priority for operation for each room or per block is previously determined, and a control circuit, which controls a damper based on the priority, is provided. CONSTITUTION:When an all room operation switch 21 is turned on, an automatic control damper 26 which is attached at a branching port 25 of a branching chamber 24 reaching a room with first priority, is controlled to be fully open, and at the same time, an indoor unit is controlled to be under a high load operation. When the room with first priority reaches a set temperature, and a signal is input from a thermostat, a control circuit 22 controls a damper for a room with second priority to be fully open, and controls the damper for the room with first priority to be slightly open. Rooms with third priority and rest are controlled in the same manner. By this method, the rising for a large room with a large load such as living room can be improved.

摘要： PURPOSE:To solve the problem that the heat from solar radiation, etc., during the day remains indoors and keeps unabated even in the nighttime by a method wherein the outside air temperature and room temperature are monitored and, when the difference in temperature therebetween exceeds a certain range, the ventilation is effected by automatic selection of the ventilation mode. CONSTITUTION:The temperatures inputted from an outside air-temperature detective sensor 14 and from room-temperature detective sensors 15 are monitored, the former sensor 14 being provided inside a ventilating duct 1 and the latter sensors 15, inside rooms. When the difference in temperature therebetween exceeds a certain range, a ventilating fan in a ventilating unit 2 is actuated to effect automatic ventilation of the rooms by drawing in outside air through outside-air duct 1 ventilating unit 2 indoor apparatus 4 branch chamber 8 branch ducts 11 outlets 12. As a result, it does not occur that the heat inside the room remains into midnight and keeps almost unabated and that the air conditioning requires a large consumption of heat energy at the start because of a large load. Therefore, this method is especially effective in a house built so airtightly and so heat-resistantly that heat is easily trapped indoors.
