Background
With the emphasis of the national projects of energy conservation and emission reduction, the heat pump hot water saving system is increasingly popularized and applied in power saving control of schools, enterprises, factories and the like. Meanwhile, new development of efficient energy-saving (water-saving and electricity-saving) systems brings updated Yan Jun challenges to the energy-saving industry. When people use hydropower in daily life, the following unresolved problems exist:
1. Along with the modern process, the households of people draw in water and electricity, so that great convenience is brought to the life of the human society, meanwhile, the living floors of the human beings are higher and higher, each household is provided with a water and electricity meter, if the data are read for each household each month, the water and electricity cost is increased, and besides, the water and electricity cost and the labor intensity of meter reading personnel or the errors of meter reading caused by human factors and the like can be possibly caused.
2. Because the number of the user members is large, the meter reading is performed manually, the water and electricity management is inconvenient, the phenomenon of electricity and water stealing is likely to occur, and the loss of resources cannot be effectively prevented.
3. In centralized hot water supply systems, such as hot water supply systems in schools, hospitals, factories, hotels and other units, even more than one set of energy-saving hot water systems are arranged on each building in a newly built district, from tens of buildings to hundreds of buildings, and the hot water systems are basically arranged on the ceilings of each building, so that the water supply amount and the temperature control during four seasons of exchange can not be effectively managed under the condition of temperature difference change. For example, fifty degrees are supplied in winter days and fifty degrees are supplied in summer days and twenty-several degrees; for another example, in winter, a user may only need ten tons of hot water a building a day, and in summer, only five tons of hot water a day. The hot water supply cannot be effectively managed or managed by no person, twelve tons of hot water are supplied every day, and a large amount of resource waste is caused.
4. When a water meter device or a hot water supply device fails, the situation cannot be immediately reversed, for example, a single user's water meter or electric meter is bad, and only when the meter is read out at the end of a month, the situation can be found, due to inaccurate data, how to charge the user, which may cause related disputes of the user, while when the hot water supply fails, a hot water tank on the building may still have hot water, the user can find the failure without the hot water, repair the water meter by repair personnel, wait until the repair is completed, and the period may be two to three days apart. Thus, not only is the inconvenience brought to the life of users brought, but also more users are put into operation, and more water vending losses are brought to hot water investors.
The traditional heat pump controller is integrated, and one controller realizes the control of devices such as a blower, a condensing fan, an actuator, a temperature air door, a mode air door, a valve body, a temperature sensor, a compressor, a heater and the like.
