(5) specific embodiment
The utility model is unit as shown in Figure 2, and this unit is by direct combustion type one-level high pressure generator 7, direct combustion type secondary high pressure generator 4, evaporimeter 16, absorber 10, low pressure generator 14, condenser 15, high-temperature heat exchanger 2, low temperature heat exchanger 1, solution pump 17, cryogenic fluid pump 18, control system (not shown) and connects the direct-fired lithium bromide absorption type cold water two occurred frequently that pipeline, valve constituted, the hot and cold water unit of each parts.Described direct combustion type secondary high pressure generator 4 and direct combustion type secondary high pressure generator 4 are arranged on the solution circulation line with series system, promptly, feed tube 6 occurred frequently (high-temperature heat exchanger weak solution drain pipe) is received on the direct combustion type one-level high pressure generator 7, be provided with solution cross over pipe 8 occurred frequently (the liquid outlet position of one-level high pressure generator is higher than the inlet position of secondary high pressure generator) between direct combustion type one-level high pressure generator 7 and the direct combustion type secondary high pressure generator 4, drain pipe 12 occurred frequently (high-temperature heat exchanger intermediate solution feed tube) picks out from direct combustion type secondary high pressure generator 4; The refrigerant vapour outlet of direct combustion type one-level high pressure generator 7 and direct combustion type secondary high pressure generator 4 is all received on the refrigerant vapour pipe 13; On the drain pipe occurred frequently 12 of direct combustion type secondary high pressure generator 4 and the pipeline between the absorber 10, solution transfer valve 9 is housed; On the pipeline between refrigerant vapour pipe 13 and the evaporimeter 16, steam transfer valve 11 is housed.
During the unit refrigerating operaton, solution transfer valve and steam transfer valve are closed, the weak solution of being exported from absorber by solution pump is through low temperature heat exchanger, the high-temperature heat exchanger heat exchange heats up after feed tube occurred frequently enters direct combustion type one-level high pressure generator, the heat heating of being joined the generation of one-level burner 5 combustion fuels by direct combustion type one-level high pressure generator concentrates, concentration, temperature goes out direct combustion type one-level high pressure generator after raising, under the difference in height effect, enter direct combustion type secondary high pressure generator through solution cross over pipe occurred frequently, the further heating of heat that is produced by direct combustion type secondary two stage burner that high pressure generator is joined 3 combustion fuels is condensed into intermediate solution, after intermediate solution goes out direct combustion type secondary high pressure generator, after entering high-temperature heat exchanger heat exchange cooling, drain pipe occurred frequently enters low pressure generator; In the direct combustion type one-level high pressure generator and the refrigerant vapour that produces in the direct combustion type secondary high pressure generator all in the refrigerant vapour pipe enters the heat exchanger tube of low pressure generator, thereby make unit realize two high pressure generators, double burner heating operation.When direct combustion type one-level burner that high pressure generator is joined was stopped transport, direct combustion type one-level high pressure generator was only as the flow of solution passage; Equally, when direct combustion type secondary burner that high pressure generator is joined was stopped transport, direct combustion type secondary high pressure generator was only as the flow of solution passage.
During the unit heat supply running, solution transfer valve, steam transfer valve are opened, and the solution that goes out Direct Fired High Pressure Generator through drain pipe occurred frequently directly enters absorber, and the high temperature refrigerant vapour that produces in the Direct Fired High Pressure Generator directly enters evaporimeter.
The type of one-level burner and two stage burner is according to the fuel situation apolegamy of application places.During unit operation, the startup of one-level burner and two stage burner, stop and the adjusting of fuel combustion amount control is controlled according to air conditioner load, the fuel type that preferentially uses set in advance by the control system of unit, make unit can use two kinds of operating fuels at the same time or separately, and preferentially use cheap fuel, insufficient section just uses high-grade fuel and replenishes, and realizes economical operation.
The cooling water flow path of unit is flow process in parallel (as shown in Figure 2), also serial flow (as shown in Figure 3).
Solution transfer valve, steam transfer valve and tube connector thereof in cancellation Fig. 2, Fig. 3 unit, unit promptly becomes the direct-fired lithium bromide absorption type cold water unit two occurred frequently (as shown in Figure 4) that is used for separate refrigeration.
