[detailed description of the invention]
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As shown in Figure 1, be structural principle and the circuit theory diagrams of modular group of water heater of the present invention, each monoblock comprises two air-source water heaters, and those skilled in the art can also select other quantity as required, such as 3,4 or multiple stage.Multiple air-source water heaters used in the present invention are all identical.Every platform air-source water heater has a main frame 9, every platform main frame 9 connects a water tank 1, and all water tanks 1 are attemperater, and the sustained height place of all water tank 1 bottoms offers connected entrance, adopt communicating pipe 20 to be communicated with between connected entrance on water tank 1, make the water level of all water tanks 1 keep identical.Each water tank 1 is equipped with cooling water inlet 5, hot water outlet 16, circulating hot water import 6 and circulating water outlet 18; Every platform water heater host 9 is equipped with circulating water import 7 and circulating hot water outlet 8, each circulating water import 7 and the circulating water on the water tank corresponding to its main frame exports 18 by pipeline communication, and each circulating hot water exports between the circulating hot water import 5 on 8 and water tank corresponding to its main frame and passes through pipeline communication; Described circulating water import 7 and circulating water export on the pipeline between 18 and are provided with water circulating pump 19, cooling water inlet 5 on each water tank is connected outside cold water source by cold water arm 13 with water supply pump 11, hot water outlet 16 on each water tank 1 passes through hot-water branch 15 and is connected to out hot water house steward, go out hot water house steward and be provided with heat-exchanger pump 14, go out hot water house steward and connect shower set 22.
In above-mentioned design, every platform main frame 9 is responsible for the water circulation heating in a water tank 1, every platform main frame 9 can independent operating work, linker is formed by communicating pipe 20 between water tank 1 and water tank 1, when certain main frame 9 damages, the work of other main frames 9 can not be affected, the supply ensureing hot water can also be continued.The present invention adopts modular unit design, installs the relatively smaller water tank of multiple specification 1, and such as two capacity are 1m
3water tank, the user demand of track train can be met.The quantity of main frame 9 can according to water consumption, the size etc. of regional space to be installed is determined, more than two can be designed, preferably scheme arranges two, and the number of corresponding water tank, temperature controller, water circulating pump, temperature sensor is also two, because the weight of water tank 1 is larger, two water tanks 1 are arranged on the right and left of the compartment longitudinal axis of track train, and maintenance balanced weight, thus can not have an impact to the balance of vehicle body, ensure stablizing when driving a vehicle.
As shown in Figure 1, dotted portion also show the annexation of circuit control device, a water level control system is set in each modular unit, this water level control system comprises central processing element 3, the high water level switch 4 be connected with central processing element 3 input, low-water level switch 2, central processing element 3 output is connected with relay; The outlet connected electromagnetic valve 12 of described water supply pump 11; Described relay is connected with the magnetic valve 12 of described water supply pump; Described high water level switch 4, low-water level switch 2 are arranged within any one water tank 1; Described central processing element 3 is for when low-water level switch 2 disconnects, make relay closes, thus make that water supply pump 11 starts, magnetic valve 12 is opened, start to moisturizing in water tank 1, when low-water level switch 2, high water level switch 4 all close, relay is disconnected, thus makes that water supply pump 13 stops, magnetic valve 12 cuts out, stop to water tank 1 moisturizing.By above-mentioned, the automatic water supplement that can realize water tank is set.
