(7) heating mode
Air-conditioning fast heating water-storage type water heater changes with water tank temperature variation efficiency, and water temperature is higher, and efficiency is lower, otherwise and Height makes full use of the advantage of air-conditioning fast heating water-storage type water heater efficient cryogenic, is heated at water temperature low temperature with air-conditioning fast heating water-storage type, Higher water temperature i.e. thermoelectricity heating or the electromagnetic energy heat hot water constant using calorific value.
(8) divide Wen Jiare
Cold season, the temperature difference is big, and amount of hot water changes greatly, needs regulating tank temperature to guarantee hot water supply, hot water temperature is lower than can When adjusting 45 DEG C, heated by single air conditioning fast heating water-storage type water heater, medium temperature is adjustable 45-55 DEG C when, by air-conditioning fast heating water-storage type heat Hydrophone and i.e. thermoelectricity heating work at the same time completion, high temperature is adjustable 55-75 DEG C when, by individually be thermoelectricity heating complete.
(9) high temperature sterilization
Because water tank cold water from low side into, hot water height is brought out, and sewage is caused to deposit, form the nutrient laden of water, along with water temperature it is lower, Just it is suitble to bacterial reproduction, need to periodically sterilizes, when water temperature is lower than adjustable 55 DEG C, is heated, be higher than by air-conditioning fast heating water-storage type water heater Or when being equal to adjustable 55 DEG C, start water pump, open bypass solenoid valve, starting is thermoelectricity heating, forms circulating heater to can 75 DEG C are adjusted, high temperature sterilization.
(10) priority routine
When water tank temperature will be above setting temperature, for protection equipment and energy conservation, when 5 DEG C adjustable higher than setting temperature, refrigeration or water Water heating is not converted when flowing switch connection, when water tank temperature is 5 DEG C adjustable less than or equal to setting temperature, when water flow switch is connected Refrigeration conversion water heating or starting device heat hot water.
