摘要： PROBLEM TO BE SOLVED: To improve a connection decision accuracy for a hot-water pipe in a hot-water air conditioner having a connection determination means for determining whether or not the hot-water pipe is normally connected.SOLUTION: This invention relates to a hot-water air conditioner for heating an indoor side with hot-water supplied from a heat source machine to a heat exchanger through a hot-water pipe. The air conditioner has connection determination means for determining an erroneous connection state if a water temperature Tw within a water feeding pipe passage is kept to be lower than a determination reference water temperature T4 continuously for a prescribed reference time S4 or longer, a return side hot-water pipe is connected to the water feeding side hot-water pipe connection part, a going-side hot-water pipe is connected to a water discharging side hot-water pipe connection part. The connection determination means sets the determination reference water temperature T4 low if an initial room temperature Ta is low and sets the determination reference water temperature T4 high if the initial room temperature Ta is high.

摘要： PROBLEM TO BE SOLVED: To prevent generation of water hammer in stopping a cascading hot water operation and to stop cascading hot water with high responsiveness, in a cascading hot water device including a cascading hot water nozzle 41 for making the warm water heated by a heat exchanger 51 for hot water supply, of a heat source machine 5 fall into a bathtub.
SOLUTION: This cascading hot water device includes a cascading hot water solenoid valve 46 disposed in a cascading hot water pathway 42 for supplying the warm water from the heat exchanger 51 for hot water supply to the cascading hot water nozzle 41, a water amount adjustment valve 44 disposed on a part of the cascading hot water pathway 42 at an upstream side with respect to the cascading hot water solenoid valve 46, a draining pathway 47 branched from a part of the cascading hot water pathway 42 between both valves 44, 46, and a draining solenoid valve 48 disposed in a draining pathway 47. In stopping the cascading hot water operation, the cascading hot water solenoid valve 46 is closed after opening the draining solenoid valve 48, and then the draining solenoid valve 48 is closed after decreasing the water amount by the water amount adjustment valve 44.

摘要： PROBLEM TO BE SOLVED: To provide a technology capable of detecting unexpected gas kind combustion more quickly and effectively. SOLUTION: A controller 40 of a gas fan motor is equipped with a totalization means 47 for determined a total using time after start of use, a forced combustion means 43 for performing forced combustion at a prescribed gas flow rate as long as a prescribed time from ignition, a temperature comparison means 48 for comparing an index on an appliance inside temperature enabling monitoring of the combustion state of a gas burner 21 with a threshold, a rotational frequency comparison means 49 for comparing the rotational frequency of a fan 23 for hot wind with a threshold, and an unexpected gas detection means 44. The unexpected gas detection means 44 determines whether the unexpected gas kind combustion occurs or not based on a comparison result by the temperature comparison means 48 and a comparison result by the rotational frequency comparison means 49 only during an initial stage of appliance use wherein the total using time does not exceed a prescribed time.
