Device processed is served only for control water heater and the balance of air-conditioning heats.
It is well known that the thermal efficiency of heat pump system is several times of the electric heating thermal efficiency, in the case where consuming equivalent electric energy,
Heat pump system can exchange heat times over the thermal energy of electric heating generation；Also, the environment temperature that exchanges heat is lower, is more conducive to and high temperature system
Cryogen heat exchange, the heat exchange rate of high temperature refrigerant is faster, however, it is preferential if setting air-conditioning for air-conditioning water-heating dual-purpose system,
High temperature refrigerant is not flowed into for water heater 7 before air conditioning exhausting temperature not up to sets leaving air temp, water heater 7 at this time
Water outlet is all electrically heated using the first electric heating part 703, with the raising of indoor environment temperature, indoor heat exchanger 3 and room
Interior environment heat exchange difficulty increases, and heat exchange rate is slack-off, and entire heat pump system is in underrun state at this time, and at electric heating
In heavy-duty service state, it is unfavorable for saving electric energy.
In technical scheme, air-conditioning heating and 7 heat production of water heater balance are got up, when water heater 7 is with greater need for heating
A greater amount of high temperature refrigerants just is used to generate hot water, is just used for a greater amount of high temperature refrigerants when air-conditioning is with greater need for heating
Generate warm wind, whether the leaving water temperature of water heater 7 is not up to and sets the leaving air temp of leaving water temperature or air conditioner not in this way
It up to setting leaving air temp, is preferentially exchanged heat using high temperature refrigerant, is conducive to the utilization rate for promoting heat pump system, is conducive to
It reduces electric heating to use, is conducive to save electric energy, promotes electricity consumption economy.
It should be noted that the heat-production control method of the application runs only for control water heater and air conditioning balance, as
Air-conditioning and the respective control of water heater can be carried out according to the method for existing design, namely: it is not achieved in air conditioning exhausting temperature and sets
When making air temperature, auxiliary heater 20 can also be controlled, the refrigerant for entering the room heat exchanger 3 is heated, assisted certainly
Heater 20 also can directly be exchanged heat with indoor environment, and the temperature for being equally beneficial for indoor environment is rapidly achieved set temperature,
To meet requirement of the user to air conditioning exhausting temperature as early as possible, similarly, setting leaving water temperature is not achieved in the leaving water temperature of water heater 7
When, it can also be heated by water outlet water flow of first electric heating part 703 to water heater 7, to meet user as early as possible to hot water
The requirement of 7 leaving water temperature of device；Certainly, the whether unlatching of the second electric heating part 2004 or the first electric heating of auxiliary heater 20
Part 703, which is opened, can all cause the temperature difference before and after corresponding heating member to increase, therefore the aperture of flow control valve 19 can also be caused to change,
To balance the operation demand of water heater and air-conditioning.
For example, the first electric heating part 703 first is opened when opening water heater 7 during the stable heating of air-conditioning, the first electricity adds
The temperature difference of the front and back of warmware 703 increases, and first temperature difference increases, and it is larger that controller recognizes first temperature difference, just by flow control valve 19
Aperture reduce, water is heated by the first hot water heat-exchanging loop 6 and the first electric heating part 703 together, water heater 7 is avoided to occur individually
Electrically heated situation is conducive to save electric energy in this way, is conducive to promote electricity consumption economy.
Therefore, on the one hand, technical scheme passes through the first electric heating part 703, the second electric heating part 2004 and heat pump
System tripartite energy supply, so that air-conditioning under heating condition, is conducive to ensure that water heater 7 is rapidly achieved setting leaving water temperature, and
Advantageously ensure that air-conditioning is rapidly achieved setting leaving air temp；On the other hand, technical scheme is by 7 heat production of water heater and air-conditioning
In contrast thermal equilibrium control processed makes entire air-conditioning water-heating dual-purpose system, more use heat pump system heat supply, and reduce as far as possible
The use of first electric heating part 703 and the second electric heating part 2004 is conducive to save electric energy, is conducive to promote electricity consumption economy.
Selectively, the first water tank 701 can also have preset low water level, high water level and limit temperature value, the first water
Water level sensor and temperature sensor are equipped in case 701, temperature sensor is equal and water level sensor is communicated to connect with controller,
It is the when the water temperature of the first water tank 701 is higher than preset limit temperature value or when the water level of the first water tank 701 is lower than low water level
One water tank, 701 moisturizing, until detecting that the water temperature of the first water tank 701 is high lower than the water level of limit temperature value and the first water tank 701
Stop moisturizing when low water level；Preferably, moisturizing to the first water tank 701 water temperature lower than 10 degrees Celsius below limit temperature value and
The water level of first water tank 701 stops moisturizing when being higher than low water level；Certainly, if when water level reaches high water level in the first water tank 701
Water temperature be still higher than limit temperature value (or be higher than limit temperature value or less 10 degrees Celsius), then stop moisturizing and control third electromagnetism
Valve 17 is closed.
Preferably, when temperature sensor detects that the temperature in the first water tank 701 is greater than limit temperature value, controller control
Third solenoid valve 17 processed is closed, and is the first water tank when water level sensor detects the water level of the first water tank 701 lower than low water level
701 moisturizings.
Selectively, it is opened simultaneously in air-conditioning with water heater, and when air-conditioning is in heating condition, except through comparison first
It, can also be using the third temperature difference and the 4th temperature difference outside aperture of the size of the temperature difference and second temperature difference to control flow control valve 19
It compares to control the aperture of flow control valve 19, the third temperature difference is the exhausted of the difference of 7 leaving water temperature of water heater and setting leaving water temperature
To value, the 4th temperature difference is air conditioning exhausting temperature and the absolute value of the difference for setting leaving air temp；If the third temperature difference is greater than the 4th temperature difference,
The aperture for then tuning up flow control valve 19 makes the cold medium flux in the first hot water heat-exchanging loop 6 is opposite to increase, makes indoor heat exchanger
The opposite reduction of refrigerant flow in 3；If the third temperature difference turns the aperture of flow control valve 19 down, makes room less than the 4th temperature difference
The opposite increase of refrigerant flow in interior heat exchanger 3, makes the cold medium flux in the first hot water heat-exchanging loop 6 is opposite to reduce.
