Description of the Related Art Conventionally, in air conditioners for heating and cooling, refrigeration equipment, etc., which have been installed in homes, business establishments, fresh markets, etc., a cooling cycle for cooling the outside with latent heat of vaporization of the refrigerant, or conversely high temperature compression BACKGROUND ART A heating cycle that heats the outside by liquefying heat when a high-pressure refrigerant is radiated by a condenser to be liquefied is used to cool or heat the inside of a room, or cool a refrigerator or a freezer room. Refrigerant circulating in the cycle of this air conditioner or refrigeration equipment gradually leaks to the outside, and cooling and heating efficiency and refrigeration efficiency decrease, so a gas cylinder filled with liquid refrigerant inside is regularly transported to the site, and the gas cylinder Is connected to an air conditioner or refrigeration equipment to replenish the refrigerant in the cycle.
Further, in recent years, liquefied petroleum gas filled in a gas cylinder has been used in cooking rooms such as general households and restaurants because it has a higher thermal power than city gas.

の問題があった。However, in the winter when the ambient temperature is low, the liquid refrigerant filled in the gas cylinder increases in viscosity and is difficult to vaporize. Hot water is stored in a bucket and transported to the site where air conditioning and refrigeration equipment are installed, which cannot be replenished,
It is necessary to immerse the gas cylinder in hot water and heat it while filling the air conditioner and the refrigeration equipment with the refrigerant, which has a drawback that it takes a lot of trouble to carry and immerse the hot water to the site. Also, in the case of liquefied petroleum gas, butane and the like contained in liquefied petroleum gas are less likely to vaporize in the winter, so the combustion efficiency is low and the gas cylinder is equipped with a heat insulating material to keep it warm However, there was a problem that the combustion efficiency could not be increased sufficiently.
