Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is set forth further.
Source, energy saving and environment friendly ground of the present invention central air conditioner system, comprises the water intake system connected successively, work system, coil pipe heat exchanger system 21 and return water system.
As shown in Figure 1, water intake system of the present invention comprises wet well 1, immersible pump 2, hydrocyclone 3 and hydrotreater 4, the immersible pump 2 be placed in wet well 1 extracts deep phreatic water and removes sand grains in water through hydrocyclone 3, then removes the impurity in water, algae and various microorganisms etc. through hydrotreater 4.The water that water intake system takes out is entered in the energy-storage thermal-insulating case 8 of work system by water inlet hand sluice valve 5 and water feeding one-way valve 6.
As shown in Figure 1, work system of the present invention is the relevant device in equipment machine room 19, mainly comprise energy-storage thermal-insulating case 8, water circulating pump 14, electric cabinet 20 and relevant supporting hand sluice valve, check valve, various sensor composition, energy-storage thermal-insulating case 8 is provided with semiconductor refrigeration system 7 and high-frequency heating body 9.
As shown in Figure 1, energy-storage thermal-insulating case 8 of the present invention is formed by welding after stainless steel 304 light sheet bending.Semiconductor refrigeration system 7 is installed outside energy-storage thermal-insulating case 8, semiconductor refrigeration system 7 can make the water temperature in energy-storage thermal-insulating case 8 maintain lower level in summer, and all the other outsides of energy-storage thermal-insulating case 8 are stained with heat or not too fast the scattering and disappearing of cold that the thick rubber and plastic heat-preservation cotton of 30MM ensures system.Wherein high-frequency heating body 9 is placed in energy-storage thermal-insulating case 8, uses for heating heating cold season.High-frequency heating body 9 adopts drawer structure modularized design, and being convenient to increases and reduce, and also facilitates M R.Be configured with temperature sensor 10 in water tank and can detect water temperature in energy-storage thermal-insulating case 8, control the quantity that high-frequency heating body 9 drops into winter and make temperature maintain about 60 °.The frequency that summer controls immersible pump 2 and water circulating pump 14 by electric cabinet 20 regulates its power output to reach maintenance water temperature at about 18 °, as water temperature can not meet the demands under field conditions (factors), then reduces water temperature further by semiconductor refrigeration system 7.The start and stop also having low water level sensor 11 and high water level sensor 12 to control immersible pump 2 in energy-storage thermal-insulating case 8 carry out the water in supplementary energy-storage thermal-insulating case 8.Water tank is provided with draining hand sluice valve 26, and being also provided with overfall can directly turn back to water in back water well 27.Energy-storage thermal-insulating case 8 of the present invention, makes summer water cycle process be: water is back to underground from underground water intake, work system, coil pipe heat exchanger system 21, return water system by water intake system, and then by water intake system from underground water intake; Winter, water cycle process was: water intake system forms new circulation from underground water intake, work system, coil pipe heat exchanger system, return water system by being directly back to work system.In duty process of the present invention, the temperature taking full advantage of underground water in summer is lower than the water temperature after backflow, and winter underground water temperature generally higher than the temperature of recirculation water, the mode of operation that two kinds different can not be adopted, the result of use of air-conditioning can be ensured when reducing energy resource consumption.
As shown in Figure 1, the water that energy-storage thermal-insulating case 8 flows out enters water circulating pump 14 through the first hand sluice valve 13.The coil pipe heat-exchange system 21 flowed to through the second hand sluice valve 15, check valve 16 in building is pumped by it.Wherein the configuration of the first hand sluice valve 13 and the second hand sluice valve 15 facilitates the maintenance of water circulating pump 14.Pipeline after check valve 16 is provided with pressure sensor 17 and temperature sensor 18.The descaling line pressure signal that pressure sensor 17 gathers as the conditioning signal of electric cabinet 20 controlled circulation water pump 14, also as the guard signal of system, can ensure the safe operation of equipment.Temperature sensor 18 confirms whether supply water temperature meets the requirement of system.
As shown in Figure 1, enter return water system after the heat in coil pipe heat exchanger system 21 pairs of building construction things exchanges, return water system comprises minimum pressure valve 23, the 3rd hand sluice valve 24 and backwater hand sluice valve 25.When needing heating in the winter time, the water absorbing heat directly returns energy-storage thermal-insulating case 8 through minimum pressure valve 23, the 3rd hand sluice valve 24; When needing refrigeration summer, the water that coil pipe heat exchanger system 21 flows out directly is discharged to backwater through minimum pressure valve 23 and backwater hand sluice valve 25 and enters in 27.The pipeline of coil pipe heat exchanger system 21 and minimum pressure valve 23 is provided with return water temperature sensor 22.The temperature of the measurement of return water temperature sensor 22 determines as winter the reference dropping into high-frequency heating body 9 input quantity.Arranging of minimum pressure valve 23 can regulate pipeline system pressure, also control system can get back to the water yield of energy-storage thermal-insulating case 8.
Electric cabinet 20 Main Function pick-up transducers data of the present invention, and the work of the device such as controlled circulation water pump 14, semiconductor refrigeration system 7, high-frequency heating body 9 as requested, electric cabinet 20 control device of the present invention can adopt PLC controls, as the PLC device of Siemens, select corresponding touch-screen as human-computer interaction interface, can select winter and summer like this, Methodistic control system safe operation.
In summer, open into water hand sluice valve 5, first hand sluice valve 13, second hand sluice valve 15 and backwater hand sluice valve 25.Close the 3rd hand sluice valve 24 and draining hand sluice valve 26.Electric cabinet 20 reaches the heat exchange demand of response coil pipe heat-exchange system 21 fast according to the frequency of return water temperature sensor 22 temperature-controlled circulation water pump 14.The water level of energy-storage thermal-insulating case 8 is controlled by low water level sensor 11 and high water level sensor 12.The moisturizing when low water level sensor 11 action of immersible pump 2, when high water level sensor 12 action, the stopping time stops moisturizing.
In the winter time, open into water hand sluice valve 5, first hand sluice valve 13, second hand sluice valve 15 and the 3rd hand sluice valve 24.Close backwater hand sluice valve 25 and draining hand sluice valve 26.Electric cabinet 20 controls the input quantity of heating generator 9 according to return water temperature sensor 22, temperature sensor 10 and temperature sensor 18, responds the heat exchange demand of coil pipe heat-exchange system 21 fast.The frequency that the pressure signal of pressure sensor 17 carrys out water circulating pump 14 reaches stable system pipes pressure.The water level of energy-storage thermal-insulating case 8 is controlled by low water level sensor 11 and high water level sensor 12.The moisturizing when low water level sensor 11 action of immersible pump 2, when high water level sensor 12 action, the stopping time stops moisturizing.Air-conditioning system of the present invention is as in extremely cold area, and the period of heating at night or do not need, the mode that underground water can be adopted to circulate in systems in which, in case antipriming pipe freezes, so both can keep pipeline to run unimpeded, and also reduce energy consumption as much as possible.
The too much water that is in operation can flow into back water well 27 from overflow pipe.Check and maintenance time, draining hand sluice valve 26 can be opened and bleed off water in energy-storage thermal-insulating case 8 in back water well 27.
