Description
Technical field
The utility model relates to a kind of suction-type lithium bromide heat-exchange system.Belong to air conditioner technical field.
Background technology
In conventional central heating system, a secondary net hot water is after thermal source place is by heat temperature raising, is sent to each heat user by heating network, after each heat user place and secondary network hot water are lowered the temperature by heat exchanger heat exchange, then returns thermal source place heat temperature raising by heating network.
The ordinary heat exchanger that each heat user place uses as shown in Figure 1 (being water-water heat exchanger in diagram), one secondary net hot water and secondary network hot water carry out heat exchange by heat exchanger tube (shell-and-tube heat exchanger) or heat-transfer surface (plate type heat exchanger), heat in one secondary net hot water is delivered in secondary network hot water, one secondary net hot water temperature declines, secondary network hot water temperature raises, complete the process of secondary network hot water heat-obtaining from a secondary net hot water, secondary network hot water be transported to again with thermal field institute for produce or live, heating.By configuring multiple heat exchanger, the different hot water demands (different pressures or different temperatures) at same heat user place can be met.
For reducing heating network construction cost and heat delivery cost, needing the supply water temperature of increase one secondary net hot water as far as possible or reducing its return water temperature, to increase supply backwater temperature difference, thus reducing required flow when carrying identical heat.But because the heatproof of heating network limits, the supply water temperature of a secondary net hot water can not be too high.And the ordinary heat exchanger adopted, a secondary net hot water and secondary network hot water need certain heat transfer temperature difference could realize effective heat exchange, so the return water temperature of a secondary net hot water in theory need higher than the inlet temperature of secondary network hot water.After the temperature of secondary network hot water is determined, the return water temperature of a secondary net hot water is restricted, and the utilized temperature difference of a secondary net hot water is subject to the restriction of secondary network hot water temperature.If can new flow process and system be adopted, when ensureing secondary network hot water temperature, reduce the return water temperature of a secondary net hot water, break through its restriction bottleneck higher than secondary network hot water inlet temperature, then can realize the object of aforementioned minimizing heating network construction cost and heat delivery cost.
In addition, heat demand during cold snap most because of central heating system demand fulfillment, thus heating network is all the design and establishing carried out according to maximum heating demand, but in actual moving process, the heating system overwhelming majority time is all run under part heating demand, and this just causes the waste of heating network heat capacity.If can new flow process and system be adopted, the peakload of heat supply peak period is fallen by the device assumes of heat user, central heating network is made only to bear basic load to a certain degree, then in same set under heat capacity, the construction cost of heating network can reduce, the oepration at full load time lengthening of heating network, the investment utilization ratio of heating network can get a promotion.
