Among four plate 21 to 24 that make up a refrigerant container, an intermediate plate 22 in contact with a heat receiving plate 21 is so provided with semi-annular peripheral channels 221 that they surround a boiling area of a refrigerant and, at the same time, is provided with straight channels 222 extending from the peripheral channels 221 to the boiling area over substantially all around the circumference of the peripheral channels 221. According to this structure, even if the refrigerant container is used in a tilted position, a liquid refrigerant that has condensed completely is supplied to the boiling area through the straight channels 222 provided on the floor within the refrigerant container, after being stored in the lowest position of the refrigerant container through the peripheral channels 221 provided on the floor within the refrigerant container.

摘要:
An auxiliary heater control device can be readily attached to a hot water heating system configured with a simple water circuit without a hot water storage tank, and is capable of preventing freezing of circulating water such that use of an auxiliary heater is minimized. When a sensed temperature tS sensed by a temperature sensor is in a range, a control device increases a rotational speed of a circulation pump. When the sensed temperature tS is in a range, the control device increases the rotational speed of the circulation pump and lowers an operating frequency of a compressor. When the sensed temperature tS is in a range, the control device increases the rotational speed of the circulation pump, lowers the operating frequency of the compressor, and activates an auxiliary heater.

An object of the present invention is to provide a method and a system by which hydroxycarboxylic acid cyclic dimers are efficiently generated, allowing high yields of high-quality polyhydroxycarboxylic acid to be obtained. The method for synthesizing polyhydroxycarboxylic acid comprises a depolymerization step for depolymerizing hydroxycarboxylic acid oligomers to produce hydroxycarboxylic acid cyclic dimers, wherein, in the depolymerization step, a reaction solution is heated via heat transfer from a heat medium passage under reduced pressure while the reaction solution is being flowing through a horizontally provided reaction solution passage.
