Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an absorption heat pump device formed by a closed circulation chamber of refrigerant and absorption liquid.

There are two types of absorption heat pumps: one is a so-called absorption refrigerating machine with the intake side and the heat radiation side reversed, and is configured to utilize the heat on the radiation side, and the other is a type that utilizes the degree of heat response when an absorption liquid absorbs refrigerant. removes heat at a high temperature level from a heat source at a low humidity level1)
There is a special pump machine that can be used.

The absorption heat pump device Wl of the present invention improves the latter of these two types of heat pumps, and uses a W heater to control the humidity of the cold V& liquid supplied from the condenser to the evaporator. By having a structure in which the refrigerant liquid, which has become humid and has reached a temperature close to that of the evaporator, flows into the evaporator, the purpose is to: 1) regulate the output of the heat pump and improve operational efficiency; be.

Embodiments of the present invention will be explained below with reference to the drawings showing embodiments of the present invention.
1) is an upper shell containing an evaporator (2) and an absorber (3), and (4) is a lower shell containing a generator (5) and an ampere (6). The body is airtight via a refrigerant pipe (8) with a cold g, y pump (7), an absorption liquid pipe RIG with an absorption liquid pump (9), an absorption H dice tube (company), a heat exchanger ■, etc. The evaporator (2) is connected to the evaporator (2), and the evaporator (2) is equipped with a liquid cooling g*as and a cold II Zenp α4 that sprays liquid refrigerant from the top of the evaporator (2).
5) and the evaporator (2) are supplied with a low-humidity heat source fluid (hereinafter referred to as low-temperature heat t/I7) such as heated wastewater and hot spring water, respectively, to absorb and drive the pump device. Heater Q8
In Q6, a condenser (6) is equipped with a cooler system that cools and liquefies the refrigerant vaporized in the generator (5).
3) Hot water or steam for hot water supply and space heating can be output from the heat exchanger.

For example, use lithium bromide as the absorption liquid, water as the refrigerant, exhaust steam at 98°C as the low humidity heat source, and 25°C as the cooling water for the condenser (6).
When water is used before and after, water vapor at approximately 130° C. is obtained from heat exchanger ①, as shown in the Dueling diagram in Figure @2.

In other words, the absorption liquid that returns from the absorber (3) and is sprayed from the upper part of the generator ω is heated by the heat supply device ω, and the refrigerant is vaporized and separated. While being sent to the condenser (6), the concentrated liquid having a high absorption liquid concentration is distributed by the absorber (3) by the absorption liquid pump +911=. Furthermore, the refrigerant gas that has flown into the S condenser (6) I is cooled and liquefied by the cooler Qη, and then supplied to the evaporator (2) by the refrigerant pump (7). 2) will be dispersed. Like this
The cold KM sprayed as ≦ receives heat from the heat supply device ②, flows into the absorber (3) while being vaporized, and is absorbed by the absorption liquid sprayed in the absorber (3).

On the other hand, the heat of reaction during absorption of this refrigerant causes the heat exchanger to absorb the absorbed liquid and gaseous refrigerant that flow into the absorber (3)! ] is also heated to high humidity, and the load (19, low temperature heat source 1) is capable of supplying high temperature water or steam at high humidity levels. In such a system, ω is a refrigerant heater that heats the refrigerant liquid so that the humidity of the refrigerant supplied from the condenser (6) to the evaporator (5) approaches the humidity of the evaporator as much as possible. In this embodiment, the generator (5) and the evaporator (2
) The waste heat from the low-temperature heat source after heating the absorption liquid or refrigerant is used as a supporting heat source.

In the absorption heat pump device, the pump (7).

+9), Q41, heat supply ωα・, heat exchanger 0, αη, I
Since the capacity of equipment such as MI is set based on the maximum load condition (100 m load), as the load decreases, the amount of refrigerant vaporized in the evaporator (2) and the generator (5) will decrease. The amount of refrigerant generated is also limited, and the refrigerant pump (7) that supplies liquid refrigerant from the condenser (6) to the evaporator (2) is also operated intermittently.

However, if the cold II liquid lagoon of #condenser (6) (for example, 112
In the diagram in the figure, 30℃) is evaporated by pump I.
) is circulating in the refrigerant fIl humidity (approximately 80°C) and the dross S) is low, and the sump (7) is operated and the evaporator (2)
When the refrigerant liquid is distributed in the evaporator (2) while liquid refrigerant is being supplied to the evaporator (2), and when the pump (7) is stopped and the cooling liquid is distributed only by the evaporator, the evaporator (2) Refrigerant fI/! As a result, the amount of refrigerant vaporized in the evaporator (2), and therefore the amount of heat generated in the absorber (3), in other words, the humidity of hot water and steam taken out from the heat exchanger (I). , or the amount of heat extracted was likely to change significantly, resulting in poor operating efficiency as a heat pump. However, in the present invention, since the condensed cooled v & liquid heated by the refrigerant heating device ω is supplied to the evaporator (2), the condenser (6
) to the evaporator (2), the cold gFf1 can be distributed in the evaporator (2) with little influence due to the temperature conditions of the refrigerant supplied from the refrigerant to the evaporator (2), and the refrigerant vaporization can be performed in accordance with the size of each load. Since the amount can also be controlled, the humidity of leakage water and steam produced by an absorption heat pump (from ¥11) can be controlled, and fluctuations in the heat source produced can be reduced. This enables efficient heat pump operation with a fixed output.

In addition, Fig. 3 is a diagram showing an embodiment of the pond of the heat pump device of the present invention.11 The same equipment as in Fig. 1 is indicated by the same figure number, and 0 indicates an electric heater for heating the refrigerant liquid, etc. (2) It is a heating device.
