Description
Technical field
The utility model relates to a kind of cold and hot lithium bromide absorption cold and hot water of taking-up type simultaneously unit, belongs to the heat transmission equipment technical field.
Background technology
The cold and hot in the past lithium bromide absorption cold and hot water of taking-up type simultaneously unit (referring to the unit that thermals source such as fuel oil, combustion gas, flue gas directly drive, down together) as shown in Figure 1.Unit increases hot water heat exchanger 12 on high pressure generator 1 on the basis of the direct-fired lithium bromide absorption type cold water unit of standard, user's heating hot water is provided by the mode of hot water in the direct heat hot water heat exchanger of refrigerant vapour occurred frequently, refrigerant vapour coagulates water and directly gets back to high pressure generator, cold water can be provided separately, hot water can be provided separately, also can hot and coldly provide simultaneously.Provide separately cold water or hot and cold when providing simultaneously independent heating solution switch valve 10 be in closed condition, the cooling condition operation press in the solution circulation of unit, refrigerant vapour pressure height occurred frequently at this moment can obtain the hot water of higher temperature.Independent heating solution switch valve 10 is in opening when providing hot water separately, solution is after solution pump is squeezed into the high pressure generator heating, directly got back in the absorber 4 by the solution conduit that is provided with independent heating solution switch valve 10, this moment, the saturation temperature of solution was corresponding with pressure occurred frequently.Even the corresponding saturation temperature of refrigerant vapour pressure occurred frequently is at 62 ℃, the temperature of solution occurred frequently also will reach about 105 ℃, if saturation temperature rises to 72 ℃, the temperature of solution occurred frequently also will rise to nearly about 120 ℃, as reduce solution temperature, can reduce the temperature difference between hot water and refrigerant vapour adiabatic condensation temperature, but need to increase the heat exchange area of hot water heat exchanger, increase cost.If need produce the hot water of higher temperature, solution temperature also needs to increase substantially, and cause the heatproof of solution pump to require height, and the radiation loss of unit is big, the exhaust gas temperature height, and the thermal efficiency is low.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of cold and hot lithium bromide absorption cold and hot water of taking-up type simultaneously unit is provided, and makes this unit under the constant situation of solution temperature, can reduce the heat transfer area of hot water heat exchanger; Under the suitable situation of solution temperature, can improve the heating heat-exchange efficient of unit.
The purpose of this utility model is achieved in that a kind of cold and hot lithium bromide absorption cold and hot water of taking-up type simultaneously unit, comprise that high pressure generator, low pressure generator, condenser, evaporimeter, absorber, high-temperature heat exchanger, low temperature heat exchanger, solution pump, cryogenic fluid pump and hot water heat exchanger and solution advance pipe occurred frequently, it is characterized in that: advance to set up solution on the pipe occurred frequently at solution and advance the hot water heat exchanger pipe, in hot water heat exchanger, set up liquid distributor, and advance to set up a solution valve I on the pipe occurred frequently at solution.When independent heating operation, solution enters the hot water heat exchanger spray on the hot water heat-exchanging tube bundle.The solution valve that solution advances pipe occurred frequently is in closed condition, and other operating mode is in opening.
The cold and hot lithium bromide absorption cold and hot water of taking-up type simultaneously of the utility model unit can also advance to set up solution valve II on the hot water heat exchanger pipe at described solution.When independent heating operating mode, be in opening, be in closed condition in other operating mode.
The utility model adds hot water generator with the solution that entered high pressure generator originally when independent heating, spray the heat exchanger tube surface by spray equipment, absorbs refrigerant vapour occurred frequently, heats the hot water in the heat exchanger tube simultaneously.The hot water mode of heating is absorbed the refrigerant vapour heating by original refrigerant vapour heating becoming solution occurred frequently.Because under operating condition, the saturation temperature of solution is higher 40～50 ℃ than refrigerant vapour saturation temperature occurred frequently, with the original system ratio, under the constant situation of solution temperature, the heat transfer temperature difference of hot water heat exchanger hot water and solution is far longer than the heat transfer temperature difference that former hot water and refrigerant vapour condense, and can reduce the heat transfer area of hot water heat exchanger; Under the suitable situation of solution temperature, the maximum temperature of hot water can reach more than 90 ℃, improves the permission outlet temperature of hot water greatly.Under the constant situation of hot water temperature, solution temperature occurred frequently descends, and exhaust gas temperature occurred frequently can reduce, and the bulk temperature of unit descends, and radiation loss reduces, and improves the heating heat-exchange efficient of unit.
