・Ｖ５を設けている。2. Description of the Related Art Conventionally, a cooling water pipe of this type of absorption chiller / heater generally includes an absorber 1 and a condenser 2 which are the main body side of the absorption chiller / heater C as shown in FIG. An on-off valve V4 is connected to the cooling water pipe 5 so that the tower 3 side can be thermally separated when necessary.

る。Then, the on-off valves V4 and V5 are closed, the operation of the cooling water pump P1 is stopped, and the refrigerant and the absorbing liquid heated to a high temperature by the generator (not shown) are supplied to the evaporator 4 and the absorber 1
Is heated directly through the heat transfer pipe 41 provided in the evaporator 4 to heat the water flowing inside the cold / hot water pipe 6, and the hot water is supplied to the load side by the cold / hot water pump P2. During a heating operation or a hot water supply operation (hereinafter simply referred to as hot water supply) performed by supplying water, the cooling water in the cooling water pipe line 5, which is heated by the heat transfer pipe 11 provided in the absorber 1 and has a high temperature of 80 ° C. However, it does not flow into the cooling tower 3.

ると云った不都合があるためである。[0004] Since the cooling tower 3 is generally installed at a high place such as a well-ventilated roof, it is necessary to make the cooling tower as lightweight as possible. This is because, when the high-temperature water is sent as described above, each part is deformed and there is an inconvenience that a failure occurs.

などを生じることがないようになっている。[0005] When hot water is supplied with the on-off valves V4 and V5 closed, the cooling water pipe 5 on the absorber 1 and condenser 2 side is opened.
The temperature of the cooling water in the cooling water rises and expands, and a large thermal stress is generated in the cooling water pipeline in this portion, so that cracks and the like are easily generated. For this reason, between the absorber 1 and the condenser 2 of the cooling water pipe 5 and the cold / hot water pipe 6 of the evaporator 4 are communicably connected through a bypass pipe 9 provided with an on-off valve V6. Even if the cooling water on the side of the absorber 1 / condenser 2 expands during the supply of hot water, cracks or the like are not generated in the piping.

合があった。However, in the absorption chiller / heater C having the above configuration, when the supply of hot water is switched to the supply of chilled water, the cooling water remaining in the heat transfer tube 11 of the absorber 1 becomes as high as 80 ° C. when the hot water is supplied. So the absorber 1 and condenser 2
When the high-temperature water held by the cooling water pipe line 5 on the side of the cooling water naturally radiates heat and is suitable for cooling water, for example, when a cooling layer (not shown) of the cooling tower 3 is formed of a vinyl chloride resin material. Waits for the temperature to drop to 50 ° C or less, and the switching is performed. In the case of a large-scale device, the amount of cooling water held is large, so the time is considerably long, and the waiting time for supplying cold water is long. There were inconveniences such as a surge of complaints to the operator.

た不都合があった。Also, since the on-off valves V4 and V5 have large diameters, there is a problem that the price is extremely high for a solenoid valve that can be automatically opened and closed. In such a case, the driver must manually perform the operation each time, so that not only is the operation switching operation complicated, but also the response is delayed and the air conditioning characteristics are degraded.

A technique has been proposed in Japanese Utility Model Laid-Open No. 62-80160, in which high-temperature cooling water is prevented from flowing into the cooling tower 3 even if cold water is supplied immediately after hot water is supplied. ing.

Since the air is introduced into the passage and the on-off valve V7 is opened, the cooling water is completely extracted from the cooling water pipe 5, and the air is filled instead. For this reason, when the cooling water pump P1 is started to pump the cooling water from the cooling tower 3 and the supply of the cooling water is started, the automatic air release valve V
Since the air that could not be exhausted from 8 flows through the cooling water coil 5D together with the cooling water, there is a disadvantage that a loud noise such as an unpleasant rumbling is always produced when switching to the cooling water supply. Furthermore, when air cannot be completely removed, cavitation of the cooling water pump P1 occurs,
There was a possibility that the cooling water would not flow at all.

When the water is supplied directly to the evaporator, the water flowing through the cold / hot water pipe is heated through the heat transfer tube of the evaporator by this heat, and the hot water is supplied to the load side by the cold / hot water pump to perform the heating operation. Since the operation of the cooling water pump is only stopped, the upward movement of the cooling water heated to a high temperature through the heat transfer tube of the absorber is prevented by the U-shaped portion provided at the outlet of the condenser. In addition, the high-temperature cooling water is prevented from flowing into the cooling tower.

切り換えが短時間で可能になり、空調特性が向上する。Claim 2 : When switching from hot water supply to cold water supply, it flows through a cold / hot water pipe to perform a heating action,
By returning the water that has returned after the temperature has dropped back to the cooling water pipe with the cooling water pump stopped by opening the on-off valve of the medium-temperature water supply pipe, the water returns through the heat transfer pipe in the absorber. The cooling water in the cooling water pipe, which has been heated to a high temperature, is gradually extruded, and a part of the water moves toward the cooling tower while mixing, and during this time, heat is radiated to the outside air and the temperature decreases. Cooling water does not flow. Therefore, the cooling tower does not need to have a heat-resistant structure, and there is no need to wait until the high-temperature cooling water heated by the absorber naturally releases heat when the hot water is supplied and the temperature drops, so the operation from hot water supply to cold water supply is not required. Switching can be performed in a short time, and the air conditioning characteristics are improved.

The refrigerant heated to a high temperature by a generator (not shown) and the absorption liquid are directly supplied to the evaporator 4 and the absorber 1 to evaporate. When the water flowing through the cold / hot water pipe 6 is heated via the heat transfer pipe 41 provided in the vessel 4 and this hot water is supplied to the load side by the cold / hot water pump P2 to perform the heating action, the cooling water Only the operation of stopping the cooling water circulation to stop the operation of the pump P1 prevents the cooling water heated to as high as 80 ° C. from flowing into the cooling tower 3 through the heat transfer tube 11 provided in the absorber 1. .

When the temperature of the cooling water is higher than a predetermined temperature, for example, 50 ° C. (usually in this state), the control signal is output from the controller 10 to open the on-off valve V2 of the medium-temperature water supply pipe 7 so that the heating operation is performed during the previous hot water supply Then, the medium-temperature water (40 to 50 ° C.) whose temperature has fallen and returned through the cold / hot water pipe 6 is supplied little by little to the inlet side of the absorber 1 of the cooling water pipe 5, and the heat transfer pipe 11 of the absorber 1 is supplied.
This is gradually extruded while being partially mixed with the cooling water which has been heated to a high temperature by heating, and is moved to the cooling tower 3 side, so that heat is radiated in the long cooling water pipe 5 on the way. Then, when the temperature of the cooling water measured by the temperature sensor T1 becomes lower than the predetermined temperature, the controller 10 closes the on-off valve 2, and then starts the cooling water pump P1 to circulate the cooling water to enter the cooling water supply. become.

There is an advantage that switching from hot water supply to cold water supply can be performed in a short time. Further, there is an advantage that the operation is simple and the manufacturing cost can be reduced because the large-diameter on-off valves V4 and V5, which are required in the conventional absorption chiller / heater, are not required.

Instead of the U-shaped portion 51 described in the absorption chiller / heater A of the first embodiment, the inlet side of the absorber 1 and the outlet side of the condenser 2 are connected by a bypass pipe 8 provided with an on-off valve V3 in the middle. The configuration is such that communication is possible.

The convection that low-temperature cooling water enters causes no high-temperature cooling water from the absorber 1 and the condenser 2 to flow into the cooling tower 3 at a high position.

In this case, too, the cooling water heated by the absorber 1 and having a high temperature can be cooled in a short time without flowing into the cooling tower 3 and the cooling water can be supplied.
