Another decline in individual set water temperature, when another during cold water temperature to be dropped to multiple set water temperatures, condenser
Radiating reaches maximum, and family expenses water dispenser is of short duration to shut down, when pausing between when reaching three preset time thresholds, family expenses water dispenser
Optimal refrigerating state is adjusted to, family expenses water dispenser carries out refrigerating operaton again.So constantly circular flow, in tank
Water temperature fall too low very low, for example water temperature is down to into default target water temperature, can so pass through batch (-type) refrigeration control side
Formula completes refrigeration.
In addition, it is necessary to explanation, multiple set water temperatures can be arranged in descending order, by the way that intermittently refrigeration cold water temperature can be gradually
Decline until reaching target water temperature.For example, multiple set water temperatures may include water temperature 1, water temperature 2 and water temperature 3, wherein, water temperature 1
More than water temperature 2 and water temperature 2 be more than water temperature 3, and water temperature 3 be target water temperature.So, family expenses water dispenser is carried out after refrigerating operaton, cold
Coolant-temperature gage first declines to water temperature 1, and when cold water temperature reaches water temperature 1, family expenses water dispenser is temporarily stopped.Is reached between when pausing
During three preset time thresholds, family expenses water dispenser re-starts refrigerating operaton, and cold water temperature to water temperature 2 declines, when cold water temperature reaches
During water temperature 2, family expenses water dispenser is temporarily stopped.When reaching three preset time thresholds between when pausing, family expenses water dispenser is carried out again

Further, judge that satisfaction restarts condition when time out is more than three preset time thresholds.It is of course also possible to
Judge whether that satisfaction restarts condition according to other conditions, whether the temperature of such as condenser is less than preset temperature threshold value.
It should be noted that timing can be carried out to time out by the 3rd timer.More specifically, when family expenses water dispenser is temporary
When stopping refrigeration, controllable 3rd timer proceeds by timing to record time out from 0.
Family expenses water dispenser proceeds by refrigerating operaton, and cold water temperature begins to decline, when between evaporator temperature and cold water temperature
Temperature difference be less than the 3rd preset temperature threshold value when, meet time-out condition, family expenses water dispenser is temporarily stopped, and then condenser is to sky
Quick heat radiating in gas.When reaching three preset time thresholds between when pausing, family expenses water dispenser is adjusted to optimal refrigerating state, meets

Environment temperature can be detected by the 4th temperature sensor on family expenses water dispenser shell.More specifically, the first TEMP
Device may be installed the end of condenser to detect the temperature of condenser ends.
Further, judge that satisfaction restarts condition when time out is more than three preset time thresholds.It is of course also possible to
Judge whether that satisfaction restarts condition according to other conditions, whether the temperature of such as condenser is less than preset temperature threshold value.
It should be noted that timing can be carried out to time out by the 3rd timer.More specifically, when family expenses water dispenser is temporary
When stopping refrigeration, controllable 3rd timer proceeds by timing to record time out from 0.
Family expenses water dispenser proceeds by refrigerating operaton, and cold water temperature begins to decline, and the temperature of condenser begins to ramp up, when
When temperature difference between the temperature and environment temperature of condenser is less than the 4th preset temperature threshold value, judgement meets time-out condition,
Family expenses water dispenser is temporarily stopped, and then condenser is to quick heat radiating in air, the temperature rapid decrease of condenser.Between when pausing
When reaching three preset time thresholds, family expenses water dispenser is adjusted to optimal refrigerating state, and satisfaction restarts condition, then, family expenses water dispenser
Refrigerating operaton is re-started, cold water temperature continues to decline, and the temperature of condenser continues to rise, when the temperature and ring of condenser
When temperature difference between the temperature of border is less than the 4th preset temperature threshold value, family expenses water dispenser temporarily ceases operating again.Between when pausing
When reaching three preset time thresholds, family expenses water dispenser is adjusted to optimal refrigerating state, and family expenses water dispenser carries out refrigerating operaton again.So
Constantly circular flow, the water temperature in tank drops very low, for example, water temperature is down to into default target water temperature,
So refrigeration can be completed by batch (-type) refrigeration control mode.
In other words, the temperature difference between condenser temperature and environment temperature can be made to remain at maximum temperature difference, is beneficial to house
Radiated to air with water dispenser, when the difference of condenser temperature and environment temperature is less than the 4th preset temperature threshold value, family expenses water dispenser is again
