Description
Technical field
The present invention 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 the heated intensification in thermal source place, is sent to each heat user by heating network, after passing through heat exchanger heat exchange cooling at each heat user place with secondary network hot water, returns thermal source place heat temperature raising again through heating network.
The ordinary heat exchanger (being water-water heat exchanger in diagram) as shown in Figure 1 that each heat user place uses, 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, completing secondary network hot water process of heat-obtaining from a secondary net hot water, secondary network hot water is transported to thermal field for producing or life, heating again.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 conveying cost, it is necessary to increase the supply water temperature of a secondary net hot water or reduce its return water temperature, to increase supply backwater temperature difference, thus reducing required flow when carrying identical heat as far as possible.But owing to 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 needs to be higher than the inlet temperature of secondary network hot water in theory.After the temperature of secondary network hot water is determined, the return water temperature of a secondary net hot water is restricted, and the available temperature difference of a secondary net hot water is by the restriction of secondary network hot water temperature.If new flow process and system can 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 aforementioned minimizing heating network construction cost and the purpose of heat conveying cost.
Additionally, because central heating system needs to meet heat demand during most cold snap, thus heating network is all the design and construction that carry 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 has resulted in the waste of heating network heat capacity.If new flow process and system can be adopted, the peakload of heat supply peak period is undertaken by the equipment of heat user, central heating network is made only to undertake a degree of basic load, then under identical central heating ability, 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.
