摘要： PURPOSE: To impart a fast-heating characteristic at a firing and to improve a rising at the start of a heating operation in the combustor with a carburetor by a structure wherein a heavy heat pipe is arranged between a combustion chamber and the carburetor.
CONSTITUTION: Between the combustion chamber 4 and the carburetor 7, a gravity type heat pipe 10 for heating a vaporization chamber 8 of the carburetor 7 is arranged. The heat pipe 10 is embedded at the horizontal part at the lower end into the lower part of a burner 5 in the combustion chamber 4 and at the rising part at the upper end into the carburetor 7. At the firing of the burner 5, a heater 9 of the carburetor 7 is supplied with electric power to heat the carburetor 7. In this instance, the carburetor 7 is separated from the side wall 1 of the combustion chamber 4 and a pipe 10 has only a small thickness and hence a small heat capacity. Further, the pipe 10 does not transmit the heat from the upper end to the lower end. Therefore, the heat generated by the heater 9 is not transmitted to the combustion chamber 4, whereas the vaporization chamber 8 reaches immediately a desired temperature. This produces the instant vaporization of a mixture of fuel and air upon being introduced into the vaporization chamber 8, and the vaporized mixture is then fed to the burner 5.

摘要翻译：目的：为了赋予燃烧时的快速加热特性，并且通过具有燃料室和化油器之间的重型热管的结构，通过化油器在燃烧器的加热运转开始时提高上升。构成：在燃烧室4和化油器7之间配置有用于加热汽化器7的蒸发室8的重力式热管10。热管10在下端的水平部分嵌入燃烧室4中的燃烧器5的下部，并且在上端的上升部分嵌入化油器7.在燃烧器5的点火时，化油器7的加热器9被供给电力以加热化油器7.在这种情况下，化油器7与燃烧室4的侧壁1分离，管道10仅具有小的厚度，因此具有小的热量容量。此外，管道10不将热量从上端传递到下端。因此，加热器9产生的热量不会传递到燃烧室4，而蒸发室8立即达到期望的温度。这会在引入蒸发室8时产生燃料和空气的混合物的即时蒸发，然后将蒸发的混合物进料到燃烧器5。

摘要： PURPOSE: To set the temperature and pressure within the vessel at a value less than a defined value to prevent the escape of the coolant by forming the end part of the vessel for sealing and enclosing a coolant for cooling an electronic apparatus or the like into a curvature shape and providing a plug having a melting point lower than that of a material for the vessel at a part of the vessel.
CONSTITUTION: The end part 1' of the vessel 1 is formed into a curvature shape, and a plug 3 made of a material having a melting point lower than that of the vessel 1 is applied to a small hole 2. By this construction, even when an inner pressure is generated in the vessel, the end part 1' undergoes no deformation unlike the case of the conventional vessel 1. Therefore, there is no possibility that any gap is generated between the small hole 2 and the plug 3. The coolant sealed in the vessel 1 prevent from escaping out.

摘要： PURPOSE:To enable to control an indoor air temperature without necessitating a complicated cooling medium circuit and provide a dehumidifying function to the device by a method wherein an independent heat exchanger having a big thermal capacity is provided at the air outlet port of a machine body. CONSTITUTION:The heat exchanger (dehumidifier) 10 having a big thermal capacity is provided at the blow-out side of a fan 9 in an indoor unit for the separate type air conditioner. The dehumidifier 10 is equipped with dehumidifying pipes and liquid is filled within the pipes. The air having a high temperature and humidity under room heating is contacted with the surface of the dehumidifier 10 having a low temperature and is dehumidified. Even when room cooling is effected, water drips of the surface of the dehumidifier 10 are not evaporated substantially since the relative humidity of the blow-out air under room cooling is substantially 100%, therefore, the dehumidifying function of the dehumidifier 10 is effected based on the difference of absolute temperatures at a point B and the point C. By providing the dehumidifier 10 in such a manner, not only the temperature variations may be absorbed but also moisture may be removed from the air having a high temperature and humidity under room heating.

摘要： PURPOSE:To minimize a required power, by a method wherein a controller consisting of a heat medium amount adjuster and a function generator is mounted, and a water amount of a cooling and a blow amount of a fan are adjusted. CONSTITUTION:A controller 100 consisting of a water amount adjuster 101 and a function generator 102 is mounted. After a water amount adjuster 101 receives a signal from a measuring device 2, it sets a most suitable water amount, and the set signal is outputted to a water amount adjusting valve 11. Meanwhile, the function generator 102 computes a most suitable blow amount according to the water amount so set to output the value to a fan 12. This adjusts a water amount of a cooling coil (not shown) according to the measurements of an environment condition in a room 2 and permits running of the fan at the most suitable blow amount of the fan having a functional relationship with said water amount. The power of a pump 11 for a cooling coil and of the fan 12 for duct can thus be minimized.

摘要： PURPOSE:To decrease the number of fans as well as to restrick a decrease of air volume by a method wherein a condenser with fans and an evaporator are installed at the upper and lower ventilation holes in a house, and are connected by a liquid flow down pipe communicating with a vapor transporting pipe, a tank and a raised pipe with a heater. CONSTITUTION:To the upper and lower ventilation holes 5 and 6 of a house are installed a nonreversible fan 6A, but facing direction thereof is changeable, evaporator 10 and condenser 11, and they are connected by the liquid down pipe 13 communicating with the vapour transporting pipe 12, tank 14, and a raised pipe 15 having a motor 16. As an example, when the indoor is to be cooled, a warm surrounding air 3 outside the housing is flowed into the ventilation hole 6 by the fan 6A and then the contaminated air in the room 2 is discharged at the ventilation hole 5. During this operation, the liquid 17 in the evaporator 10 is evaporated, passed through the transporting pipe 12, flowed into the condensor 11 and liquified therein. The condensed liquid is flowed into the raised pipe 15 through the tank 14, boiled by the heater 16. The boiled air bubbles suck up the liquid by a pumping action, then flow into the evaporator 10 from the down pipe 13. The above processes are repeated.

摘要： PURPOSE:To take out heat from heat accumulator at a high efficiency, by reducing resistance to heat transfer from heat accumulating material to cooler. CONSTITUTION:When coolant is passed through cooler 3 for absorbing heat, volatile liquid 5 existing in the vicinity of cooler 3 is cooled. By the temperature difference thus caused, volatile liquid 5 existing inside communicating passages 7 receives heat produced from heat accumulating material 2, from the inner surface of passages 7. As the result, liquid 5 is boiled and carried near to the upper cooler 3, where it is condensed through releasing of condensation heat. This volatile liquid 5 is carried back to the lower passages 7. Through repetition of the above cycle, liquid-like heat accumulating material 2 is condensed and crystal 2a of heat accumulating material sticks onto the inner wall surface of passages 7 in reservoir chamber 6. When thickness of the crystal 2a has increased to a certain value, supply of coolant to cooler 3 is interrupted and heating medium is passed through heater 4. With such an arrangement, resistance to heat transfer from heat accumulating material 2 to cooler 3 can be reduced with no need of considerably increasing the overall length of pipes constituting the cooler 3 and heater 4.

摘要： PURPOSE:To solve the problems such as the wasteful radiation of condensed latent heat, by coinciding the starting of radiation operation with the initiation of condensation of the heat accumulating material at the heat accumulator utilizing latent heat wherein condensation of heat accumulating material is accurately controlled. CONSTITUTION:Inside the heat accumulation tank 1, latent heat accumulating material 2 is filled wherein cooler 3 and heater 4 are provided. Within the material 2, seeding crystal 5 is installed which facilitate the initiation of crystallization at the time when heat is drawn from the material 2 by the function of the cooler 3 and prevent overcooling. At the bottom of the tank 1, recess 1a is provided wherein fluid 7 is located which is hard to melt with the material 2, larger in specific gravity, and never condensates within the temp. range wherein material 2 is used. Seeding crystal is installed at the tip of the moving rod 6 which enables the seeding crystal 5 protrude into the material 2 or retract within the fluid 7.
