A kind of directly-heating type water heater, comprise the First Heat Exchanger that is concatenated into the first loop, throttling arrangement and the second heat exchanger, and the compressor that is concatenated into second servo loop and the gas-liquid separator that are connected with the first loop by cross valve, the water inlet of First Heat Exchanger is provided with inflow temperature sensor and dynamoelectric water valve, the second heat exchanger is provided with environment temperature sensor outward, also be provided with and dynamoelectric water valve, environment temperature sensor, the controller that inflow temperature sensor is connected with compressor, the delivery port of First Heat Exchanger is provided with the leaving water temperature sensor and the pulse flowmeter that are connected with controller.
Be further used as the improvement of technical solutions of the utility model, inflow temperature sensor is between the water inlet and dynamoelectric water valve of First Heat Exchanger.
Be further used as the improvement of technical solutions of the utility model, leaving water temperature sensor is between the delivery port and pulse flowmeter of First Heat Exchanger.
The beneficial effects of the utility model: this directly-heating type water heater is passed to controller after detecting ambient temperature by environment temperature sensor, regulate after initial water temperature by the aperture of controller control dynamoelectric water valve, the temperature signal that inflow temperature sensor and leaving water temperature sensor detect is passed to controller, controller is according to the calculated signals unit capacity receiving, simultaneously, the flow of unit is also sent to controller by pulse flowmeter, controller comprehensively judges after detecting the unit capacity of upper 1 minute and flow, then regulate dynamoelectric water valve aperture, to stablize unit water temperature, reach the object of accurate control water temperature.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the utility model embodiment system principle schematic diagram.
The specific embodiment
With reference to Fig. 1, the utility model is a kind of directly-heating type water heater, comprise the First Heat Exchanger 3 that is concatenated into the first loop, throttling arrangement 4 and the second heat exchanger 5, and the compressor that is concatenated into second servo loop 1 and the gas-liquid separator 6 that are connected with the first loop by cross valve 2, the water inlet of First Heat Exchanger 3 is provided with inflow temperature sensor 8 and dynamoelectric water valve 10, the outer environment temperature sensor 7 that is provided with of the second heat exchanger 5, also be provided with and dynamoelectric water valve 10, environment temperature sensor 7, the controller 12 that inflow temperature sensor 8 is connected with compressor 1, the delivery port of First Heat Exchanger 3 is provided with the leaving water temperature sensor 9 and the pulse flowmeter 11 that are connected with controller 12.
This directly-heating type water heater is passed to controller 12 after detecting ambient temperature by environment temperature sensor 7, the aperture of controlling dynamoelectric water valve 10 by controller 12 regulates after initial water temperature, the temperature signal that inflow temperature sensor 8 and leaving water temperature sensor 9 detect is passed to controller 12, controller 12 is according to the calculated signals unit capacity receiving, simultaneously, the flow of unit is also sent to controller 12 by pulse flowmeter 11, controller 12 comprehensively judges after detecting the unit capacity of upper 1 minute and flow, then regulate dynamoelectric water valve 10 apertures, to stablize unit water temperature, reach the object of accurate control water temperature.
As the utility model preferred embodiment, inflow temperature sensor 8 is between the water inlet and dynamoelectric water valve 10 of First Heat Exchanger 3.
As the utility model preferred embodiment, leaving water temperature sensor 9 is between the delivery port and pulse flowmeter 11 of First Heat Exchanger 3.
After unit start, environment temperature sensor 7 detects ambient temperature, then detection signal is sent to controller 12, and controller 12 is according to the first aperture of the Signal Regulation dynamoelectric water valve 10 receiving, and while guaranteeing unit operation, water temperature approaches desired value.In the time detecting that environment temperature is high, controller 12 is controlled dynamoelectric water valve 10 and is opened greatly, and in the time detecting that environment temperature is low, controller 12 is controlled dynamoelectric water valve 10 and turned down.
Inflow temperature sensor 8 and leaving water temperature sensor 9 detect respectively inflow temperature and the leaving water temperature of unit, then detection signal are sent to controller 12, and controller 12 is again according to the calculated signals unit capacity receiving.Meanwhile, pulse flowmeter 11 detects unit flow, then detection signal is also sent to controller 12.
After 1 minute, after the ability of unit tends towards stability, controller 12 comprehensively judges after detecting the unit capacity of upper 1 minute and unit flow, then regulates dynamoelectric water valve 10 apertures, and then controls the stability of unit water temperature.
By after detecting the ability of upper 1 minute and the flow of unit and comprehensively judging, regulate dynamoelectric water valve 10 can reach 1 minute rapid hot water output, stablize the effect of water temperature.
In the time that water temperature reaches the shutdown of desired value constant temperature, ability when controller 12 records last water temperature stability automatically, as the initialization capability standard of starting shooting next time, thereby guarantees rapid hot water output and stable water temperature.
This directly-heating type water heater adopts high-precision dynamoelectric water valve 10, and it regulates aperture little, can effectively guarantee to control accuracy and the stability of water temperature.
Certainly, the invention is not limited to above-mentioned embodiment, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and the modification that these are equal to or replacement are all included in the application's claim limited range.
