Description
Technical field
The present invention relates to it is a kind of with spike heating can direct heating first kind lithium bromide heat pump unit.Belong to air-conditioning equipment
Technical field.
Background technology
Existing single-effect type first kind lithium bromide heat pump（Hereinafter referred to as heat pump）As shown in Figure 1, by condenser 1, generator
2, heat exchanger 3, absorber 4, solution pump 5, cryogenic fluid pump 6, evaporator 7 and control system（It is not shown in figure）And connecting components
Pipeline, valve constituted.Remaining hot water flows through the cooling of evaporator 7；Hot water flows through absorber 4 and condenser 1 heats up；Driving heat source stream
Through generator 2, release heat concentrates lithium-bromide solution.When operation of heat pump, extracted out by cryogenic fluid pump 6 and at the top of evaporator 7
Water as refrigerant under spray absorbs the heat for flowing through remaining hot water in 7 heat-transfer pipe of evaporator, enters in absorber 4 after being vaporized into refrigerant vapour
It is brominated the absorption of lithium concentrated solution, the heat of release is taken away by the hot water absorption flowed through in 4 heat-transfer pipe of absorber, and lithium bromide is dense molten
Concentration is thinning after liquid absorbs refrigerant vapour, is extracted out by solution pump 5 and through being added by driving heat source in the feeding generator 2 of heat exchanger 3
Thermal concentration, the refrigerant vapour for concentrating out, which enters in condenser 1, to be returned to after hot water cooling condensation in evaporator 7, and after concentrating
Lithium-bromide solution then returned in absorber 4 through heat exchanger 3.
Due to the temperature limiting by remaining hot water, the hot water temperature that heat pump is produced generally cannot or be difficult that satisfaction is practical direct
The needs of heat supply, and heat pump is unable to heat supply when no remaining hot water, therefore be substantially required for being reconfigured one after heat pump
Peaking boiler continues heat hot water.Heat pump had not only been installed in one heating plant but also peaking boiler is installed, computer room can be made to take up an area face
Product is very big, wastes land resource.And the generator that heat pump is determined according to nominal condition, heat pump can be made entirely to use process
In its maximum recoverable waste heat heat be basically unchanged, that is to say, that during heat pump use, become fine even if operating mode
More waste heats can not be recycled using the energy saving effect of heat pump, and can only be heated up to hot water by subsequent peaking boiler.
If heat pump just considers to increase generator in design, although more waste heats can be recycled when its operating mode improves, but can increase
Big heat pump cost, increases project investment, causes investment waste.Therefore, if can heat pump be put into the heating function of peaking boiler
In generator, and when realizing no remaining hot water also can direct heating, then can not only reduce computer room floor space, but also can be so that heat pump hair
Raw utensil has the ability of bigger, to increase the waste heat recovery volume of heat pump when heat pump working condition improves, ensures total heat capacity not
Increase waste heat recovery proportion in the case of change, reduce heat source consumption, realizes energy saving.
Invention content
The purpose of the present invention be exactly design it is a kind of with spike heat can direct heating first kind lithium bromide heat pump unit（With
Lower abbreviation unit）, which is combined into one first kind lithium bromide heat pump with peaking boiler, can pass through it in nominal condition
Peak load calorifier heats hot water to meet heating load demand, can reduce the heating of peak load calorifier again when operating mode improves
Amount increases heat pump heating capacity, to recycle more waste heats, increases the waste heat proportion recycled in gross heat input, is not having
It can also direct heating when remaining hot water.
The object of the present invention is achieved like this：It is a kind of with spike heating can direct heating first kind lithium bromide heat pump machine
Group（Hereinafter referred to as unit）, including：Condenser, generator, heat exchanger, absorber, solution pump, cryogenic fluid pump, evaporator, spike
Heater, hot water regulating valve, cryogen regulating valve.Unit operation and have a surplus hot water when, cryogen regulating valve close, condenser, generation
Device, heat exchanger, absorber, solution pump, cryogenic fluid pump and evaporator constitute a single-action heat pump（Hereinafter referred to as single-action heat pump）, drive
Dynamic heat source flows through generator, drives single-action heat pump recycling to flow through the heat of the remaining hot water of evaporator, absorption is flowed through for heating
The hot water of device and condenser；Generator and peak load calorifier constitute a peaking boiler, and driving heat source heats dense in generator
A part for the refrigerant vapour that contracting lithium-bromide solution generates enters peak load calorifier, after heating flows through the hot water of peak load calorifier,
Cooling condensation itself comes back to generator.Generator is ensureing that crop determines excess heat to driving single-action heat pump next time in nominal condition
In the case of, the heating amount for burden peak load calorifier of having the ability meets the total heat capacity of unit.When single-action heat pump working condition improves
（Solution concentration reduces in heat pump）When, reduce the hot water flow into peak load calorifier by turning down hot water regulating valve, to
The high temperature refrigerant vapour amount that solution concentration generates in reducing into the generator of peak load calorifier, makes it more enter condensation
The ability of device namely generator is more used to drive single-action heat pump, to which more recycling flows through the remaining hot water of evaporator
Heat, in the case where gross heat input is constant, the excess heat of recycling is more, energy saving.When not having remaining hot water, cryogenic fluid pump stops
It only runs, cryogen regulating valve is opened, and the water as refrigerant in condenser is directly entered in absorber to be mixed with lithium-bromide solution, absorber
In mixed lithium-bromide solution by solution pumped and through heat exchanger be sent into generator in by driving heat source heat concentrate, it is dense
The refrigerant vapour of contracting out divides two-way parallel connection to enter to be cooled down by hot water in condenser and peak load calorifier and condense, in peak load calorifier
Water as refrigerant return to generator, the water as refrigerant in condenser turns again to absorber through cryogen regulating valve, and the bromination after concentrating
Lithium solution also returns to absorber through heat exchanger, sprays after absorber tube surface, heating flow through the hot water in heat-transfer pipe
It is mixed with the water as refrigerant for returning to absorber.
The beneficial effects of the invention are as follows：
It is a kind of with spike heating can direct heating first kind lithium bromide heat pump unit, by first class lithium bromide absorptive heat pump
Be combined into one with peaking boiler, machine room area can be reduced, when without remaining hot water also can direct heating, and heat pump working condition become
When good, heat pump heat supply amount can be increased, reduce peaking boiler heating amount, it is energy saving to recycle more waste heat heats.
