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 are substantially all and need to be reconfigured a peaking boiler to continue heat hot water.Heat is both installed in one heating plant
Pump installs peaking boiler again, and computer room occupied area can be made very big, wastes land resource.And heat pump is determined according to nominal condition
Generator, heat pump its maximum recoverable waste heat heat in entire use process can be made to be basically unchanged, that is to say, that
In heat pump use process, more waste heats can not be recycled using the energy saving effect of heat pump operating condition becomes very well, and only
It can be heated up by subsequent peaking boiler to hot water.If heat pump just considers to increase generator in design, although can be at it
More waste heats are recycled when operating condition improves, but will increase heat pump cost, are increased project investment, are caused investment waste.Therefore, if
The heating function of peaking boiler can be put into the generator of heat pump, then can not only reduce computer room occupied area, but also heat pump can be made
Generator has bigger ability, to increase the waste heat recovery volume of heat pump when heat pump working condition improves, guarantees total heat capacity
Increase waste heat recycling proportion in the case where constant, 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 first kind lithium bromide heat pump unit (hereinafter referred to as
Unit), which is combined into one first kind lithium bromide heat pump with peaking boiler, can be added by its spike in nominal condition
Hot device, which heats hot water, can be reduced the heating amount of peak load calorifier again when operating condition improves to meet heating load demand, increases
Heat pump heating capacity increases the waste heat proportion recycled in gross heat input to recycle more waste heats.
Purpose of the utility model is realized as follows: it is a kind of with spike heating first kind lithium bromide heat pump unit (with
Lower abbreviation unit), comprising: condenser, generator, heat exchanger, absorber, solution pump, cryogenic fluid pump, evaporator, spike heating
Device, hot water regulating valve.When unit is run, condenser, generator, heat exchanger, absorber, solution pump, cryogenic fluid pump and evaporator
A single-action heat pump (hereinafter referred to as single-action heat pump) is constituted, driving heat source flows through generator, and single-action heat pump recycling is driven to flow through
The heat of the remaining hot water of evaporator, for heating the hot water for flowing through absorber and condenser；Generator and peak load calorifier are constituted
One peaking boiler, a part that driving heat source heats the refrigerant vapour that concentration lithium-bromide solution generates in generator enter point
Peak heater, after heating flows through the hot water of peak load calorifier, cooling condensation itself comes back to generator.Generator is guaranteeing to drive
Dynamic single-action heat pump is in the case where crop determines excess heat to nominal condition next time, and the heating amount for burden peak load calorifier of having the ability is full
The total heat capacity of sufficient unit.
When single-action heat pump working condition improves (solution concentration reduces in heat pump), reduce entrance by turning down hot water regulating valve
The hot water flow of peak load calorifier steams to reduce into the high temperature cryogen that solution concentration generates in the generator of peak load calorifier
Vapour amount, makes that it more enters condenser namely the ability of generator is more used to drive single-action heat pump, to more return
The heat for flowing through the remaining hot water of evaporator is received, in the case where gross heat input is constant, the excess heat of recycling is more, energy saving.
The beneficial effects of the utility model are:
The first kind lithium bromide heat pump unit that the utility model is heated with spike, by first class lithium bromide absorptive heat pump
Be combined into one with peaking boiler, can reduce machine room area, and when heat pump working condition improves, can increase heat pump heat supply amount,
Reduce peaking boiler heating amount, so that more waste heat heats are recycled, it is energy saving.
