Description
Technical field
The utility model 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 technique
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 the 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, discharges heat and lithium-bromide solution is concentrated.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 in the feeding generator 2 of heat exchanger 3 by driving heat source
Thermal concentration, the refrigerant vapour for being concentrated out enters in condenser 1 to be returned in evaporator 7 after hot water cooling condensation, and after being concentrated
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 to meet practical direct
The needs of heat supply, and there is no heat pump when remaining hot water to be unable to heat supply, therefore substantially require to be 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 in entire use process
In its maximum recoverable waste heat heat be basically unchanged, that is to say, that in heat pump use process, become fine even if operating condition
More waste heats can not be recycled using the energy saving effect of heat pump, and can only be heated up by subsequent peaking boiler to hot water.
If heat pump just considers to increase generator in design, although more waste heats can be recycled when its operating condition improves, but can increase
Big heat pump cost, increases project investment, causes investment waste.Therefore, if heat pump can 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 occupied area, but also can heat pump be sent out
Raw device has bigger ability, to increase the waste heat recovery volume of heat pump when heat pump working condition improves, guarantees total heat capacity not
Increase waste heat recycling proportion in the case where change, reduce heat source consumption, realizes energy conservation.
Utility model content
The purpose of this utility model be exactly design it is a kind of with spike heating can direct heating first kind lithium bromide heat pump machine
Group（Hereinafter referred to as unit）, which is combined into one first kind lithium bromide heat pump with peaking boiler, the energy in nominal condition
Hot water is heated to meet heating load demand by its peak load calorifier, can be reduced peak load calorifier again when operating condition improves
Heating amount, increase heat pump heating capacity, to recycle more waste heats, increase the waste heat proportion recycled in gross heat input,
It can also direct heating in no remaining hot water.
What the purpose of this utility model was realized in：It is a kind of with spike heating can direct heating first kind lithium bromide heat
Pump assembly（Hereinafter referred to as unit）, including：Condenser, generator, heat exchanger, absorber, solution pump, cryogenic fluid pump, evaporator,
Peak load calorifier, hot water regulating valve, cryogen regulating valve.Unit run and have a surplus hot water when, cryogen regulating valve close, condenser,
Generator, heat exchanger, absorber, solution pump, cryogenic fluid pump and evaporator constitute a single-action heat pump（Hereinafter referred to as single-action heat
Pump）, driving heat source flows through generator, single-action heat pump recycling is driven to flow through the heat of the remaining hot water of evaporator, for heating stream
Hot water through absorber and condenser；Generator and peak load calorifier constitute a peaking boiler, and driving heat source is in generator
The a part for the refrigerant vapour that heating concentration lithium-bromide solution generates enters peak load calorifier, and heating flows through the heat of peak load calorifier
After water, cooling condensation itself comes back to generator.In nominal condition, crop is fixed next time guaranteeing driving single-action heat pump for generator
In the case where excess heat, the heating amount for burden peak load calorifier of having the ability meets the total heat capacity of unit.When single-action heat pump work
Condition improves（Solution concentration reduces in heat pump）When, reduce the hot water stream into peak load calorifier by turning down hot water regulating valve
Amount, thus reduce into the generator of peak load calorifier solution concentration generate high temperature refrigerant vapour amount, make its more into
The ability for entering condenser namely generator is more used to drive single-action heat pump, so that more recycling flows through the remaining of evaporator
The heat of hot water, in the case where gross heat input is constant, the excess heat of recycling is more, energy saving.It is cold when there is no remaining hot water
Agent pump is out of service, and cryogen regulating valve is opened, and the water as refrigerant in condenser is directly entered in absorber to be mixed with lithium-bromide solution,
Mixed lithium-bromide solution is extracted out and is sent into generator through heat exchanger by solution pump and heated by driving heat source in absorber
Concentration, the refrigerant vapour for being concentrated out divide two-way parallel connection to enter in condenser and peak load calorifier by hot water cooling condensation, spike
Water as refrigerant in heater returns to generator, and the water as refrigerant in condenser turns again to absorber through cryogen regulating valve, and is concentrated
Lithium-bromide solution afterwards also returns to absorber through heat exchanger, and spray flows through in heat-transfer pipe in absorber tube surface, heating
Hot water after mixed with the water as refrigerant for returning to absorber.
The utility model has the beneficial effects that：
It is a kind of with spike heating can direct heating first kind lithium bromide heat pump unit, by the first lithium bromide absorption type
Heat pump is combined into one with peaking boiler, can reduce machine room area, when without remaining hot water can also direct heating, and in heat pump work
When condition improves, heat pump heat supply amount can be increased, reduce peaking boiler heating amount, to recycle more waste heat heats, save energy
Source.
