Description
Technical field
The present invention relates to a kind of efficient 1.5 effect type lithium bromide absorbing type refrigeration/source pump.Belong to air conditioner technical field.
Background technology
It is several that existing lithium bromide absorbing type refrigeration/source pump can be divided into triple effect, economic benefits and social benefits, single-effect type and two-stage generation two-stage absorption-type etc. according to efficiency of energy utilization, wherein as shown in Figure 1, the operation principle of dual effect type lithium bromide absorbing type refrigeration/source pump as shown in Figure 2 for the operation principle of single-effect type lithium bromide absorbing type refrigeration/source pump.
Single-effect type lithium bromide absorbing type refrigeration/source pump is made up of pipeline, the valve of evaporimeter 1, absorber 15, generator 16, condenser 7, heat exchanger 17, solution pump 18, cryogenic fluid pump 14, control system (not shown) and connecting components.Cold water (or waste heat source) flow through evaporimeter 1, cooling water (or heat medium water) flow through absorber 15 and condenser 7.When unit operation, the water as refrigerant of being extracted out from evaporimeter 1 top spray by cryogenic fluid pump 14 absorbs cold water (or the waste heat source) heat of flowing through in evaporimeter 1 heat-transfer pipe, after vaporization, enter absorber 15, absorbed by bromize lithium concentrated solution wherein, and release heat is in cooling water (or heat medium water); After in absorber 15, bromize lithium concentrated solution absorbs refrigerant vapour, concentration is thinning, extracted out by solution pump 18, send in generator 16 and concentrated by high temperature heat source heating through heat exchanger 17, the concentrated solution after concentrating comes back in absorber 15 and absorbs refrigerant vapour through heat exchanger 17; Concentrating and separating high temperature refrigerant vapour out enters in condenser 7, and the water that is cooled (or heat medium water) is taken away heat condensation, and again gets back in evaporimeter 1.
Dual effect type lithium bromide absorbing type refrigeration/source pump is made up of pipeline, the valve of evaporimeter 1, absorber 15, high pressure generator 3, low pressure generator 4, condenser 7, high-temperature heat exchanger 9, low temperature heat exchanger 10, solution pump 18, cryogenic fluid pump 14, control system (not shown) and connecting components.Cold water (or waste heat source) flow through evaporimeter 1, cooling water (or heat medium water) flow through absorber 15 and condenser 7.When unit operation, the water as refrigerant of being extracted out from evaporimeter 1 top spray by cryogenic fluid pump 14 absorbs cold water (or the waste heat source) heat of flowing through in evaporimeter 1 heat-transfer pipe, after vaporization, enter absorber 15, absorbed by bromize lithium concentrated solution wherein, and release heat is in cooling water (or heat medium water); After in absorber 15, bromize lithium concentrated solution absorbs refrigerant vapour, concentration is thinning, extracted out by solution pump 18, after low temperature heat exchanger 10 and high-temperature heat exchanger 9 intensifications, send in high pressure generator 3 concentrated by high temperature heat source heating, intermediate solution after concentrated enters in low pressure generator 4 after high-temperature heat exchanger 9 coolings, again heated concentratedly by the concentrated refrigerant vapour producing of solution in high pressure generator 3, the concentrated solution after concentrated comes back in absorber 15 and absorbs refrigerant vapour after low temperature heat exchanger 10 coolings; And the concentrated high temperature refrigerant vapour condensation after heated solution in low pressure generator 4 producing in high pressure generator 3, all enter in condenser 7 with concentrating and separating refrigerant vapour out in low pressure generator 4, the water (or heat medium water) that is cooled is taken away heat condensation, and again gets back in evaporimeter 1.
The difference of dual effect type lithium bromide absorbing type refrigeration/source pump and single-effect type lithium bromide absorbing type refrigeration/source pump is just: in dual effect type lithium bromide absorbing type refrigeration/source pump by high temperature heat source in (high pressure) generator concentrated solution produce high temperature refrigerant vapour, as driving heat source, solution is carried out to heating again concentrated, high temperature refrigerant vapour just enters in condenser after release heat condensation in low pressure generator, this high temperature refrigerant vapour is the equal of to have driven one by evaporimeter as thermal source, absorber, the single-effect type unit of low pressure generator and condenser composition, high temperature heat source adds the heat in cooling/heating pump assembly to obtain twice utilization, thereby efficiency of energy utilization is high, and in single-effect type lithium bromide absorbing type refrigeration/source pump by high temperature heat source in generator concentrated solution produce high temperature refrigerant vapour, directly enter in condenser, high temperature heat source adds the heat in cooling/heating pump assembly to have to once utilize, thereby efficiency of energy utilization is lower.But for dual effect type lithium bromide absorbing type refrigeration/source pump, due to the pressure in its low pressure generator and solution temperature and single-effect type lithium bromide absorbing type refrigeration/source pump basic identical, and the high pressure generator at high temperature heat source heated solution place, its pressure is substantially equal to the corresponding saturated vapour pressure of heat source temperature of low pressure generator, thereby its pressure is inevitable significantly higher than low pressure generator, as the high temperature heat source of dual effect type lithium bromide absorbing type refrigeration/source pump thermal source, its grade also must be significantly higher than single-effect type lithium bromide absorbing type refrigeration/source pump.
In the practical application of lithium bromide absorbing type refrigeration/source pump, often there is the too high situation that is not suitable for adopting dual effect type lithium bromide absorbing type refrigeration/source pump of pressure because of high pressure generator, also can only adopt single-effect type lithium bromide absorbing type refrigeration/source pump although thermal source is of high grade, thereby often cause energy waste because efficiency of energy utilization is low; Although or high pressure generator pressure while adopting dual effect type lithium bromide absorbing type refrigeration/source pump is suitable, the grade of thermal source is inadequate, and adopts the words of single-effect type lithium bromide absorbing type refrigeration/source pump to have significantly energy grade waste.If can there be way to reduce the pressure in high pressure generator, both can solve and can only adopt the sorry of single-effect type lithium bromide absorbing type refrigeration/source pump because of high pressure generator hypertonia, because making required thermal source grade, reduces the pressure decreased of high pressure generator again, thereby the energy of the middle grade of part also can be fully used, promote its utilization ratio.
