A heat transfer apparatus is provided with a refrigerant heater, a single container disposed above the refrigerant heater, and the radiator spaced from the container. The container accommodates a partitioning plate for separating the inside of the container into a gas-liquid separating chamber and a liquid-receiving chamber, and a valve body for selectively opening and closing an opening defined in the partitioning plate is disposed within the container. The valve body is driven by an electrically operated driver mounted on the container. The heat transfer apparatus is also provided with a first group of pipes for communicating the refrigerant heater and the gas-liquid separating chamber, and with a second group of pipes for communicating the gas-liquid separating chamber, the radiator, and the liquid-receiving chamber. The refrigerant heater, the gas-liquid separating chamber, and the first group of pipes constitute a heating circuit, while the gas-liquid separating chamber, the radiator, the liquid-receiving chamber, the valve body, and the second group of pipes constitute a heat release circuit.

Heat transfer apparatus

A double-cylinder type oil burner having an inner flame cylinder and an outer flame cylinder. A red-heatable cylinder is connected to the upper end of the inner flame cylinder with a secondary air inlet left therebetween. A damper mechanism for varying the opening in the upper end of the red-heatable cylinder is provided on the upper end of the red-heatable cylinder. According to this arrangement, it is possible to vary the burning rate over a wide range and to vary the red-heated area in accordance with the rate of burning.
