Abstract

To obtain a fluorocarbon-free air conditioner with high efficiency, to remove carbon dioxide, water vapor, plant spores, seeds, and artificial floaters in the air.SOLUTION: The present invention causes a pump to mix air through a small hole bored in a pipe that circulates water to a tank, and send air into the tank to create a gas phase and a liquid phase; performs pressurization while storing air in the gas phase; while cooling air from the outside of the tank, when a pressure reaches a predetermined pressure, releases air into an expansion tank; adiabatically expands air and cools the air rapidly; condenses water vapor on an inner surface of the expansion tank; causes the condensed water to adsorb dust; drains the condensed water; releases air from the expansion tank into a room to cool the room, and at the same time, causes the liquid phase to absorb carbon dioxide and dust from air; circulates them into a liquid phase open tank; when the water is saturated with carbon dioxide, depressurizes the liquid phase open tank, regenerates carbon dioxide from the liquid phase to release the carbon dioxide to the outside, or releases the saturated water to the outside and replenishes water; and during heating, supplies warm air around the tank to the inside.SELECTED DRAWING: Figure 1

Description

The present invention is a heat pump air conditioner that absorbs carbon dioxide.

Countries around the world are trying to become carbon neutral by 2050 in order to combat global warming. There is a demand for the recovery and fixation of carbon dioxide.

Japanese Patent Application No. 2021-151578 submitted by us applies for an air conditioner that uses water as a medium. There is also a description of absorbing carbon dioxide into water. The application dissolves carbon dioxide into water condensed from water vapor in the air. However, the amount of water vapor in the air is limited, and carbon dioxide contained in the condensed water becomes saturated soon after operation. Then, all the carbon dioxide contained in the air taken in cannot be recovered. The gas phase in the pressurized tank had the function of recovering carbon dioxide, but this time, the liquid phase of the pressurized tank also has the function of recovering and regenerating carbon dioxide.

A pump circulates water in the tank through a small hole in the pipe that mixes air and sends air into the tank to create a gas phase and a liquid phase. When a predetermined pressure is reached while cooling, the air is opened to the expansion tank, the air is adiabatically expanded, cooled rapidly, water vapor is condensed on the inner surface of the expansion tank, dust is absorbed by the condensed water, the condensed water is drained, and the expansion tank is drained. At the same time, the liquid phase absorbs carbon dioxide and dust in the air and circulates in the liquid phase open tank, and when the water is saturated with carbon dioxide, the pressure in the liquid phase open tank is reduced A CFC-free heat pump air-conditioning system that regenerates carbon dioxide from the air and releases it outdoors, or releases saturated water outdoors to replenish the water, and supplies the warm air around the tank indoors during heating.

To obtain an efficient air conditioner while selectively using a gas phase expansion tank and a liquid phase expansion tank according to the uses of heating, cooling, dehumidification and humidification.

Collects bacteria, plant spores, and seeds floating in the air.

A water pump is used to pump air through a pressurized tank, and the separated gas and liquid phases absorb carbon dioxide.

FIG. 1 shows a CFC-free heat pump air conditioner that uses air as a medium. The circulation pump 6 circulates the water 13 in the pressurized tank 3, and the air 14 is mixed from the pitot pipe 24 of the small hole opened in the regeneration line 7, and the air 14 is sent to the pressurized tank 3. and adiabatically compressing 9 while accumulating air in the gas phase 1. When a predetermined pressure is reached while cooling the pressurized tank 3 from the outside, the pressurized tank valve 18 is opened and the condensation line 8 is passed through the expansion tank. 4, the air 14 is opened, the air 14 is adiabatically expanded 10, cooled rapidly, the water vapor in the air is condensed on the inner surface of the expansion tank 4, the condensed water 23 is made to adsorb carbon dioxide and dust, and the condensed water 23 is surplus. The water is drained from the condensed water drain 11 by opening the condensed water drain valve 21. During cooling, the expansion tank valve 19 is opened to release air from the expansion tank 4 into the room 16 to cool the room. It absorbs carbon dioxide and dust in the air and circulates it in the regeneration tank 5. When the water 13 is saturated with carbon dioxide, the regeneration tank 5 is depressurized to regenerate the carbon dioxide and release it to the outside, or the saturated water drain valve 22 is opened to saturate. An air conditioning system of non-Freon type heat pump which discharges saturated water from a water drain 12 to an outdoor 17, opens a replenishing water valve 15 to newly replenish water, and supplies warm air around a pressurized tank 3 indoors during heating.

The pump circulates the water in the pressurized tank through a small hole made in the piping that allows air to mix and send air into the pressurized tank to create a gas phase and a liquid phase. When the pressurized tank reaches a predetermined pressure while cooling it from the outside, the air compressed from the gas phase in the pressurized tank is released into the expansion tank, the air is adiabatically expanded, cooled rapidly, and the water vapor in the air reaches the inner surface of the expansion tank. The condensed water is made to absorb carbon dioxide and dust contained in the air, and the condensed water is drained. Water is circulated from the phase to the regeneration tank, and the circulating water adsorbs carbon dioxide and dust contained in the air. When the water is saturated with carbon dioxide, the regeneration tank is depressurized and the carbon dioxide is regenerated from the liquid phase in the regeneration tank and released outdoors. A CFC-free heat pump air conditioning system that releases saturated water to the outside, replenishes the water, and supplies warm air around the pressurized tank indoors during heating.
