率の向上を行なうに好適な吸着型冷凍機に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a refrigerator that uses water as a refrigerant and a thermoreversible water-absorbing polymer as an adsorbent. The present invention relates to an adsorption refrigerator that enables separation of liquid refrigerant from an adsorbent and is suitable for preventing corrosion of equipment materials and improving operating efficiency by lowering the regenerator temperature.

収させて濃度の低い吸収溶液とする機能を備えている。As shown in FIG. 2, a conventional absorption refrigerator basically consists of various heat exchangers: a high temperature regenerator 21, a low temperature regenerator 22, a condenser 23, an evaporator 24, and an absorber 25. Here, the high-temperature regenerator 21 heats the absorption solution with low concentration to generate refrigerant vapor and increase the concentration of the absorption solution, the condenser 23 condenses the vapor refrigerant to liquid refrigerant, and the evaporator 24 The absorber 25 has a function of evaporating the liquid refrigerant again to form a vapor refrigerant, and absorbing the vapor refrigerant into the high-concentration absorption solution to form a low-concentration absorption solution.

率の向上を図っている。Refrigeration is performed in the evaporator 24, which removes heat from external cold water in a low-temperature region, and the vapor refrigerant generated at this time is transferred to the absorber 2.
5, it is absorbed by a concentrated salt aqueous solution (absorbing solution with increased concentration), and the absorbed heat is discarded to the outside. Further, the heat of condensation of the vapor refrigerant generated in the low-temperature regenerator 22 is similarly discarded to the outside through the condenser 23. As shown in the pressure-temperature diagram in Figure 3, the vapor refrigerant generated from the high-temperature regenerator is condensed in the low-temperature regenerator, and the heat of condensation is added to the absorbent solution in the low-temperature regenerator. Furthermore, steam refrigerant is generated from the refrigerant to improve efficiency.

持されている。The temperature of the high temperature regenerator is approximately 150℃, and the temperature of the condenser and absorber is approximately 40℃.
℃, the evaporator is operated at about 5℃, and in order to evaporate the refrigerant water at 5℃, the pressure of the evaporator is always lower than the saturated vapor pressure of water at 5℃, which is about 6.5wa Hg. is kept low.

により得られた蒸気冷媒を凝縮器で再度凝縮させている
。In conventional known technology, the heat of condensation of the vapor refrigerant generated from the high-temperature regenerator is used as the heating source for the low-temperature regenerator.
The heating source temperature of the high-temperature regenerator is as high as 150° C. or higher, and the liquid refrigerant required in the evaporation process is obtained by recondensing the vapor refrigerant obtained by heating the absorption solution in the low-temperature regenerator in the condenser.
そのため機器材料に使われる鋼材の腐食反応によって水

機器が大型化する。そして、冷媒を蒸気にして分離する
ため、液の状態で分離するときの１０倍以上のエネルギ
ーを必要とし、運転効率が大幅に低下する。As a result, hydrogen gas is generated due to a corrosion reaction in the steel materials used in the equipment, raising the pressure inside the equipment higher than the predetermined pressure, raising the refrigerant evaporation temperature, and significantly reducing the refrigeration capacity. In addition, a heat exchanger called a condenser is required to condense and liquefy the vapor refrigerant generated once again.
Equipment becomes larger. In addition, since the refrigerant is separated in the form of vapor, more than 10 times as much energy is required as in the case of separating the refrigerant in a liquid state, resulting in a significant drop in operating efficiency.
本発明の目的は、機器材料の腐食を防止し、入熱量を少

サイクルが繰り返えされる。According to the present invention, by filling the regenerator and absorber of an adsorption refrigerator with a thermoreversible water-absorbing polymer, the heat from the heating source causes the thermoreversible water-absorbing polymer in the regenerator to phase out. When the temperature exceeds the transition temperature, the adsorbed refrigerant is separated as liquid refrigerant. This liquid refrigerant is depressurized and enters the evaporator, where it absorbs the heat of the cold water and evaporates to cool the cold water. This cold water is used for air conditioning. The evaporated refrigerant then enters the absorber and is adsorbed by the thermoreversible water-absorbing polymer at a temperature below the phase transition temperature, and the heat of adsorption is discharged to the outside. After the regenerator completes water separation, it can be used as an absorber, so the cycle can be repeated by switching between them.

器２に入る。The heating medium pump 13 passes through the four-way solenoid valve 9 and is sent to the regenerator IA. The regenerator 1A is filled with a thermoreversible water-absorbing polymer containing sufficient refrigerant, and the heating g4
The heat from the water causes the thermoreversible water-absorbing polymer to reach the phase transition temperature or higher and separate water. The liquid refrigerant separated from the thermoreversible water-absorbing polymer passes through the three-way solenoid valve 11, is depressurized by the pressure reducing valve 8, and enters the evaporator 2.

Therefore, it is discarded from the outdoor unit 5 to the outside. The temperature of the thermoreversible water-absorbing polymer in the absorber IB is approximately 40°C, and since the vapor refrigerant from the evaporator 2 is adsorbed at this temperature, the pressure in the absorber IB at this time is 6.5 mmHg or less. Become.

り返す。When the thermoreversible water-absorbing polymer in absorber IB adsorbs water vapor to a certain extent and the internal pressure of one device reaches 6.5 anHg or more, and dehydration in regenerator IA is completed, the three-way solenoid valve and the four-way solenoid valve are turned off. In turn, regenerator IA acts as an absorber and absorber IB acts as a regenerator to repeat the same cycle.

。In this example, a thermoreversible water-absorbing polymer is used as an adsorbent, and during water separation, it is heated to a temperature higher than the phase transition temperature of the thermoreversible water-absorbing polymer to separate water, which is a refrigerant, in a liquid state. Also,
Below the phase transition temperature, the thermoreversible water-absorbing polymer is in a water-absorbing state and adsorbs the refrigerant evaporated in the evaporator in the form of water vapor.

０℃〜７０℃が適当である。When considering a cooling cycle, the phase transition temperature of a thermoreversible water-absorbing polymer must be higher than the outside air temperature in order to dissipate the heat generated when the thermoreversible water-absorbing polymer adsorbs a vapor refrigerant to the outside. However, if the temperature is too high, there will be problems with the durability of thermoreversible water-absorbing polymers and corrosion of equipment materials.
A temperature of 0°C to 70°C is suitable.

への入熱量が少なくて済み、冷凍能力の向上に繋がる。Table 1 According to the present invention, the regenerator temperature is determined by the phase transition temperature of the thermoreversible water-absorbing polymer.
It can be set to a temperature below ℃, which prevents a decrease in refrigeration capacity caused by hydrogen gas generation due to corrosion of equipment materials. Since the refrigerant can be separated in a liquid state within the regenerator, the refrigerant is not separated as vapor as in conventional refrigerators, so the amount of heat input to the regenerator is small, leading to improved refrigeration capacity.

At the same time, corrosion of equipment materials is reduced and refrigeration capacity can be improved. Since a condenser is not required, it is possible to reduce the size, weight, and cost of the device.
