摘要： PROBLEM TO BE SOLVED: To provide an air conditioner for a bathroom which can keep the temperature within a bathroom roughly constant, and hardly allow cold wind to blow upon a bather. SOLUTION: When the room temperature detected by a room temperature detection sensor 10 exceeds the thermal valve off temperature, a thermal valve 4 is closed, and when the room temperature goes down under the thermal valve on temperature, the thermal valve 4 is opened. When the temperature of the heat exchanger detected by a heat exchanger temperature sensor 6 is under a specified temperature, a circulation fan 13 is stopped to prevent the blowout of cold wind, and as the temperature of the heat exchanger goes high, the number of revolutions of the fan is raised. Moreover, when the temperature of the heat exchanger is lowering, the number of revolutions of the fan is lowered to a number less when temperature of the heat exchanger is rising. Furthermore, in case that the thermal valve is close, it sends air with a small number of revolutions from the circulation fan 13 so that it can detect the room temperature accurately while suppressing the blowout of cold wind.

摘要： PURPOSE:To form a heat exchanging composite tube in a desired shape in reduction in its weight with easy processing without damage, crack of an outer tube by forming the outer tube of plastic such as silane crosslinking polyolefin or the like. CONSTITUTION:Resin composition containing as indispensable components polyolefin, silane compound, organic peroxide and silanol condensation catalyst is extrusion molded to form an uncrosslinked polyolefin tube, and a metal inner tube havingsmaller diameter than the obtained tube is inserted into the polyolefin tube as a double tube structure 1. After the obtained double tube is bent to be formed in a desired shape, when hot water is fed to a gap between the outer tube 2 and the inner tube 3, the polyolefin as the main chain of the uncrosslinked polyolefin becomes hard crosslink through graft polymerized silane compound. Accordingly, when joints 7 are connected to both ends of the structure 1 secured in the outer tube shape to a desired shape without deflecting the outer tube at the time of bending, a heat exchanging composite tube is provided.

摘要： PROBLEM TO BE SOLVED: To provide a hot water heating system for surely performing freezing preventive operation.
SOLUTION: A hot water heating heat source machine 10 having a heat exchanger 11 and a circulating pump 12 and a bathroom heating drier 20 having a circulating fan 21, a heat exchanger 22 and a hot valve system 23 are connected by external pipes 31 and 32. A controller 10a of the hot water heating heat source machine 10 and a controller 20a of the bathroom heating drier 20 are connected so as to be bidirectionally communicable via a serial interface 40. When an ambient temperature of the hot water heating heat source machine 10 detected by a heat source ambient temperature sensor 13 drops to a heat source side freezing critical temperature or less, the controller 10a of the hot water heating heat source machine 10 transmits a valve opening command of the hot valve system 23 to the controller 20a of the bathroom heating drier 20, and performs the freezing preventive operation by starting the circulating pump 12 without burning a burner for heating the heat exchanger 11.
