Send out the refrigeration demand of device 9.
The content of the invention
The purpose of this utility model is exactly to improve superposition type double-effect unit by reducing the refrigeration demand of the second evaporator 9
The COP of group.
What the purpose of this utility model was realized in：A kind of two sections of independent superposition type double-effect lithium bromide absorption type refrigeration heat
Pump assembly, including：Low pressure generator, high pressure generator, condenser, high-temperature heat exchanger, low temperature heat exchanger, first absorb
Device, the first evaporator, the second absorber, the second evaporator, the first cryogenic fluid pump, the first solution pump, the second solution pump, the second cryogen

First absorber, another road then flows through any one in the second absorber and condenser, and two path water passes through second after converging
Another in absorber and condenser；Or point two-way, after first series connection flows through the second evaporator and the first absorber all the way,
Pass through any one in the second absorber and condenser, another road then flows through another in the second absorber and condenser
It is individual.
Improvement of the present utility model and beneficial effect are：
1st, compared with existing superposition type economic benefits and social benefits unit, the utility model eliminates closed cycle water and water pump, be changed to from
Separate to come in middle warm water and substitute the closed cycle water, warm water enters back into first after first lowering the temperature in the second evaporator in the road
Heated up in absorber.For the superposition type economic benefits and social benefits unit of some operating modes, this middle warm water all the way after being heated up through the first absorber, its
Temperature can be higher than the temperature that middle warm water enters unit, that is to say, that this heat that middle warm water absorbs in the first absorber all the way can
With the heat discharged in the second evaporator more than it, the refrigerating capacity of the second evaporator can inhale less than first in other words
The heat exchange amount of device is received, consumption high temperature heat source, double using suction-type lithium bromide is needed so as to reduce whole superposition type economic benefits and social benefits unit
The refrigerating capacity for imitating refrigeration principle to be freezed, such that it is able to improve the COP of superposition type economic benefits and social benefits unit.
2nd, compared with existing superposition type economic benefits and social benefits unit, the utility model also eliminates the first evaporator and the second evaporator
Between cryogen communicating pipe, increased the second solution pump, the second cryogenic fluid pump and cryogen water- to-water heat exchanger.First solution pump is only by first
The lithium bromide weak solution of absorber is extracted out and is sent to high pressure generator concentration, and the solution after concentration comes back to the suction of the first absorber
Receive refrigerant vapour；And after increased second solution pump then extracts the lithium bromide weak solution of the second absorber out, it is sent to low pressure generation
Device is concentrated.Because the concentration of the second absorber lithium bromide weak solution is less than the concentration of the first absorber lithium bromide weak solution,
After low pressure generator concentration is sent in the second solution pump of increase and by the weak solution of the second absorber, low pressure generator can be reduced
Temperature needed for middle solution concentration, so as to reduce the condensation exothermic temperature of its heating source-refrigerant vapour occurred frequently, thus can drop
The pressure of low high pressure generator.In the case where the lithium-bromide solution concentration for entering high pressure generator is the same, high pressure generator pressure
Lower, the temperature needed for the concentration of its solution is also lower, thus the driving heat source needed for unit operation can be reduced temperature.And
After the refrigerant vapour that solution concentration is produced in high pressure generator condenses heat release in the low pressure generator, the is returned through cryogen water- to-water heat exchanger
Lithium-bromide solution can be heated during one evaporator, so that the heat from heat source needed for reducing solution concentration, is also beneficial to improve unit
COP.
By taking 12/7 DEG C of water at low temperature out temperature, 40/45 DEG C of middle warm water out temperature as an example, due to lithium bromide weak solution
The reason such as concentration and high pressure generator pressure, 40 DEG C of the middle warm water is not suitable for being directly entered the first absorber 6.But using this specially
After a part of 40 DEG C middle warm water is cooled to 34 DEG C or so by the superposition type economic benefits and social benefits unit of profit in the second evaporator 9, the part
Middle warm water can enter in the first absorber 6, and its temperature can be lifted to 42 DEG C or so in the first absorber 6.The portion
Temperature rise of the warm water in the first absorber 6 is 8 DEG C in point, and its temperature drop in the second evaporator 9 is 6 DEG C, i.e., the second evaporation
The refrigerating capacity of device 9 about only has the 75% of the heat exchange amount of the first absorber 6, and the heat exchange amount by the first absorber 6 is that the first evaporator 7 is made
1.2 times of cold consider that then the refrigerating capacity of the second evaporator 9 about only has 0.9 times of the refrigerating capacity of the first evaporator 7.That is
Using after the superposition type economic benefits and social benefits unit of this patent, it is necessary to consume high temperature driven heat energy, former using suction-type lithium bromide dual-effect refrigeration
The overall refrigerating effect for managing to freeze about only has 1.9 times of the water at low temperature refrigerating capacity of the first evaporator 7, it will again be assumed that suction-type lithium bromide economic benefits and social benefits
The COP of refrigeration unit is 1.4, then the COP of this patent superposition type economic benefits and social benefits unit can reach about 1.4 ÷ 1.9=0.737, multiple with existing
The 0.636 of stacked unit is compared, and improves about 15.9%.And because the increased second solution pump of this patent, the pressure high of unit
Raw device pressure about there was only 250mmHg, it is necessary to high temperature driven heat source temperature only need about 140 DEG C；Were it not for the second solution of increase
Pump, be still the lithium bromide weak solution of the first absorber and the second absorber is merged with the first solution pump be sent to high pressure generator and
Low pressure generator concentrate, then the pressure of high pressure generator about be up to 750mmHg, it is necessary to high temperature driven heat source temperature about need
170℃。
