Detailed description of the invention
Understand essence of the present utility model better for convenience of those of ordinary skill in the art, below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
As shown in Figure 1, a kind of gas heater, comprise: heat exchanger 1, water admixing device 2, circulating line 3 and inlet channel 4, described water admixing device 2 is connected to the water side of heat exchanger 1, and described circulating line 3 is connected between the delivery port of water admixing device 2 and the water inlet end of heat exchanger 1, and described inlet channel 4 is connected to heat exchanger 1 water inlet end.Particularly, circulating line 3 is connected with heat exchanger 1 water inlet end by triple valve with inlet channel 4.
Wherein, inlet channel 4 is provided with water proportioning valve 5 and inflow temperature sensor 61, circulating line 3 is provided with circulating temperature sensor 62, water pump 7 and water flow sensor 8, be provided with detected temperatures sensor 63 in the water side of heat exchanger 1, be provided with leaving water temperature sensors 64 at the delivery port of water admixing device 2; One controller 9 is connected with inflow temperature sensor 61, circulating temperature sensor 62, detected temperatures sensor 63, leaving water temperature sensors 64, water proportioning valve 5, water pump 7 and water flow sensor 8.
During real work, utilize the discharge that water proportioning valve 5 controls in heating process, and setting is heated than reaching the air inflow that needed for target coolant-temperature gage, target air consumption is large.According to the actual temperature difference of water-in and water-out, set rational recovered temperature, this recovered temperature is not less than target temperature, and for avoiding overshoot temperature bigger than normal, during actual design, recovered temperature should be close with target temperature.When detected temperatures sensor 63 survey water temperature reach the recovered temperature value of setting time, gas quantity required when air inflow returns to normal work.
Concrete control mode is as follows:
1, complete after once with water, controlling startup discharge position water proportioning valve aperture being adjusted to setting.The startup discharge position of setting should meet bath comfort requirement, and in the present embodiment, the startup discharge of preferred settings is 7.5L/min.When bath water flow is greater than the startup discharge of setting, water proportioning valve 5 action, controls inflow; When bath water flow is less than the startup discharge of setting, water proportioning valve is failure to actuate.
2, when carrying out seconary water use, water heater carries out overshoot heating and recovers normal heating two heating processes.That is, after having lighted a fire, water heater heats with the air inflow being greater than target air consumption, and when the water temperature that detected temperatures sensor 63 detects reaches recovered temperature, water proportioning valve 5 resets, and water heater enters heated at constant temperature, returns to target coolant-temperature gage heating process.
In the present embodiment, target air consumption V2 is calculated by following formula:
Wherein, Cp is specific heat of water,
η is water-heater heat-exchanging efficiency,
H1 is combustion gas low heat value,
V1 is discharge,
T is target coolant-temperature gage,
T0 is inflow temperature.
Air inflow when water heater starts is more than 1.5 times of target air consumption.
The situation of change of computer heating control mode leaving water temperature in water heater restarting process that traditional heating control mode and the present embodiment provide is tested below by one group of contrast experiment.
Experiment condition: inflow temperature is 17 DEG C, the target temperature of setting is 44 DEG C, bath water flow 8L.
Scheme 1: traditional startup computer heating control mode.
Scheme 2: starting heating air consumption is target air consumption 1.5 times, recovered temperature is 44 DEG C (avoid overshoot temperature bigger than normal, therefore setting one being close to target temperature numerical value).
Scheme 3: starting heating air consumption is former air consumption 2 times, and recovered temperature is 44 DEG C.
As shown in Figure 2, wherein, curve A represents the leaving water temperature fluctuation situation of scheme 1 to experimental result, and curve B represents the leaving water temperature fluctuation situation of scheme 2, and curve C represents the leaving water temperature fluctuation situation of scheme 3.
As seen from Figure 2: scheme 1 starts in heating process, leaving water temperature is up to 44.2 DEG C, is minimumly: 40.3 DEG C, the temperature difference is: 3.9 DEG C, and reaching target temperature required time is about 75S.Scheme 2 starts in heating process, and leaving water temperature is up to 44.4 DEG C, is minimumly: 41 DEG C, the temperature difference is: 3.4 DEG C, and reaching target temperature required time is about 60S.Scheme 3 starts in heating process, and leaving water temperature is up to 44.3 DEG C, and minimum is 41.2 DEG C, and the temperature difference is: 3.1 DEG C, and reaching target temperature required time is about 50S.Therefore, control water heater startup heating process by increasing air consumption and setting rational recovered temperature, coolant-temperature gage fluctuating range can be reduced and reduce the heat time, effectively promoting bath comfort, especially, when inflow temperature and the setting leaving water temperature temperature difference are larger, effect is more obvious.
Above detailed description of the invention has been described in detail essence of the present utility model, but can not limit protection domain of the present utility model with this.Apparently, under the enlightenment of the utility model essence, the art those of ordinary skill also can carry out many improvement and modification, it should be noted that these improve and modify and all drops within claims of the present utility model.
