ル等の大型冷房機に利用されている。Conventional Technology Today, there are only two methods in practical use as a heat pump system (here, broadly interpreted as a system that generates cooling and heating heat using the reverse cycle of a heat engine). They are almost limited to the fluorocarbon compression type, which is suitable for small-sized applications, and the water-lithium bromide-based absorption type, which is suitable for large-sized applications. The former method uses a compressor driven by an electric motor to extract the heat absorption and heat generated by the phase change during compression and expansion of fluorocarbons as cooling and heating heat, and is mainly used in home air conditioners. The latter is known as a heat-driven cycle, and utilizes the phenomenon that the vapor pressure of an aqueous lithium bromide solution changes with temperature to extract the vapor latent heat of water for cooling purposes, and is mainly used in large air-conditioning machines for buildings. ing.

ロンの耐熱性はそれに十分対応することが困難である。Problems to be Solved by the Invention Regarding the Freon compression type, the device is compact and relatively efficient, and is widely used for home use. but,
Based on the view that chlorofluorocarbons, which are the working medium, are a substance that destroys the ozone layer in the stratosphere and may have a significant negative impact on the biosphere on Earth, including humans, a worldwide Opinions are beginning to come together in the direction of reducing its use and production, and there are many problems inherent in it. 3. The heat resistance of fluorocarbons makes it difficult to meet the recent demand for higher temperatures when extracting warm heat.

ない。Regarding the absorption formula of water-lithium bromide system,
There were problems such as the efficiency was not very high, it could not be used at temperatures below 0"C, air cooling was difficult, and maintenance was labor-intensive. Recently, various proposals have been made regarding methods other than these. However, it has not yet been put into practical use mainly due to problems caused by the flammability and toxicity of the working medium.

すよう構成したものである。Means for Solving the Problems In order to solve the above-mentioned problems, the present invention utilizes the heat absorption phenomenon that accompanies the absorption and desorption of carbon dioxide gas into a non-flammable, flame-retardant organic solvent. It is configured to extract warm heat and cold heat on the desorption side.

ての安全性、作動媒体の耐熱性が向上する。When a gas is dissolved (absorbed) into a liquid, an exothermic phenomenon is generally accompanied, and conversely, when a gas is desorbed, an endothermic phenomenon is generally accompanied. And its solubility usually decreases as the temperature of the system increases. However, by changing the pressure of the system, it is possible to increase the solubility on the high temperature (high pressure) side as well as on the low temperature (low pressure) side. This makes it possible to generate heat on the high-temperature, high-pressure side and absorb heat on the low-temperature, low-pressure side, and by providing a heat exchanger on each side, cold and warm heat can be taken out to the outside world. The system will constitute a heat pump system. At this time, by using carbon dioxide as the gas and a nonflammable or flame-retardant organic solvent as the liquid, the safety of the device and the heat resistance of the working medium are improved.

へは拡散しにくく、公害６／３．−。In this embodiment, carbon dioxide gas is used as the gas, and perfluorotributylamine, which is a hydrocarbon halide, is used as the liquid. An example of the results obtained when a cycle is operated using this combination will be briefly shown. High temperature and high pressure side 5
When heating was performed with Q''Cl2o pressure and the low temperature and low pressure side set to 0''C15 pressure, about 250% of the heat output was obtained with respect to the shaft input of the gas and liquid pumping machine. Also,
In this case, the high temperature side is set at 50"C, but even if the cycle is operated at about 100°C, there will be no problem since both carbon dioxide gas and perfluorotributylamine have good heat resistance. In particular, although the latter is a fluorocarbon-based substance, its vapor pressure is low, so it is difficult to diffuse into the atmosphere, resulting in pollution of 6/3.

するため、装置としての効率向上に役立つことになる。Furthermore, as a measure to improve the efficiency of the apparatus compared to the above embodiment, it is effective to increase the solubility of carbon dioxide gas in the solvent. This is a method in which a non-flammable, flame-retardant solvent is used as the main solvent and other solvents are added. For example, it is effective to add organic solvents such as glycols and glymes that physically increase solubility (absorption amount), or alkanolamine-based solvents that chemically increase solubility. When determining which (or more than one) to add and how much, it is necessary to take into account the compatibility with the base agent, the degree of flammability of the liquid after addition, etc. Furthermore, when using an aqueous solution, sufficient consideration must be given to freezing in the system near the pressure release device. However, in general, increasing solubility reduces the circulation ratio of liquid (solvent) to carbon dioxide gas (the power of the liquid pump), which helps improve the efficiency of the device.

First, because it uses carbon dioxide gas as a working medium, it has excellent thermal stability from low to high temperatures, is inexpensive, has excellent safety even in the event of a leak, and is a new product that can meet the worldwide demand for CFC-free. We can provide cooling/heating heat generation cycles and equipment. In addition, since a nonflammable and flame-retardant liquid is used as the absorption liquid, there is no danger of combustion or explosion in the event of a leak, and safety is ensured, including ease of handling during construction.
