Referring to fig. 1, fig. 1 is a schematic structural diagram of a dual-air-conditioning system according to an embodiment of the present application. As shown in fig. 1, the two-in-one air conditioning system includes: the two-unit supply unit 100 and the natural gas wall-mounted furnace 200;

the two-unit supply unit 100 comprises an outdoor unit 101, a hot water generator 102 and at least one indoor unit 103, wherein the outdoor unit 101 is connected with the hot water generator 102 through a first refrigerant pipeline, the outdoor unit 101 is connected with the at least one indoor unit 103 through a second refrigerant pipeline, the outdoor unit 101 is used for converting electric energy into first heat energy, the first heat energy is supplied to the hot water generator 102 through the first refrigerant pipeline for hot water preparation, and/or the first heat energy is supplied to the at least one indoor unit 103 through the second refrigerant pipeline for indoor heating;

The hot water generator 102 is connected with the natural gas wall-mounted furnace 200 through a first water pipeline, and the natural gas wall-mounted furnace 200 is used for converting natural gas energy consumption into second heat energy, directly performing hot water preparation by using the second heat energy, and/or continuously heating water flowing into the natural gas wall-mounted furnace 200 from the first water pipeline by using the second heat energy.

Specifically, the outdoor unit 101 may include a fan, an outdoor heat exchanger, a gas-liquid separator, a compressor, an oil separator, an oil return capillary tube, a four-way valve, and the like. The outdoor unit 101 is configured to convert electrical energy into first heat energy, and provide the first heat energy to the hot water generator 102 for hot water preparation through a first refrigerant pipeline, and/or provide the first heat energy to the at least one indoor unit 103 for indoor heating through a second refrigerant pipeline. The outdoor unit 101 may be a three-pipe outdoor unit, and may be connected to a three-pipe indoor unit and two-pipe indoor units, where the connection of the three-pipe indoor unit may also have a heating and dehumidifying function, and the connection of the three-pipe outdoor units may also have a heat recovery and heating and refrigerating function. When the hot water generator 102 is in an operation state, heat exchange can be performed with the refrigerant in the first refrigerant pipeline, heat energy absorbed from the refrigerant is transferred to the water pipeline flowing through the hot water generator 102, hot water preparation is performed, and thus the prepared hot water can be used as floor heating hot water and domestic hot water and can also flow into the natural gas wall-mounted boiler 200 from the first water pipeline for continuous heating. The at least one indoor unit 103 may include one or more triple-control indoor units, and may further include a sum of one or more triple-control indoor units and one or more double-control indoor units, which are not specifically limited in the embodiments of the present application. The indoor unit can exchange heat with the refrigerant in the second refrigerant pipeline, and transfer heat energy absorbed from the refrigerant into indoor air for indoor heating. The natural gas wall-hanging stove 200 may be used to convert natural gas energy consumption into second heat energy, and directly perform hot water preparation by using the second heat energy, and/or continuously heat water flowing into the natural gas wall-hanging stove 200 from the first water pipeline by using the second heat energy.

It should be noted that the first refrigerant pipe may include a liquid pipe and a high-pressure gas pipe of the refrigerant, and the second refrigerant pipe may include a liquid pipe and a low-pressure gas pipe of the refrigerant (for the two-pipe indoor unit), or include a liquid pipe, a low-pressure gas pipe and a high-pressure gas pipe of the refrigerant (for the three-pipe indoor unit). Specifically, the common two-pipe indoor unit can only perform independent refrigeration or heating, and the two-pipe indoor unit can perform simultaneous refrigeration or heating by being matched with the three-pipe outdoor unit; two sets of radiators are arranged in the two-pipe indoor unit and can respectively serve as an evaporator and a condenser, so that the functions of heat recovery, reheating and dehumidification can be achieved. The air-conditioning system connected with the three-tube indoor unit has the functions of simultaneous cooling, heating and heat recovery, namely one three-tube indoor unit is used for heating, the other three-tube indoor unit can be used for cooling and simultaneously supplying heat discharged by cooling to the heating indoor unit, and energy sources are saved. The dehumidification reheating mode can also be realized by connecting the three-pipe indoor unit, and the realization mode is that a low-pressure air pipe is connected with one group of radiators in the indoor unit for refrigeration and dehumidification, and the other group of radiators connected with the high-pressure air pipe is used for heating dehumidified air to realize dehumidification reheating. In conclusion, the three-pipe indoor unit is matched with the three-pipe outdoor unit to save more energy. In addition, the components such as an electromagnetic valve, a flowmeter, a check valve, an electronic expansion valve and the like can be arranged on each refrigerant pipeline and each water pipeline according to the requirements, and are used for controlling the flow direction, the flow rate, the on-off and the like of the refrigerant and the water.

In this embodiment, the two-unit air conditioning system not only can utilize the two-unit air conditioning unit 100 to perform hot water preparation and/or indoor heating, but also can utilize the natural gas wall-mounted boiler 200 to perform hot water preparation, so that the problem that in the prior art, the economic benefit is low due to the fact that the two-unit air conditioning unit 100 is independently used for indoor heating and preparing hot water can be avoided, the two-unit air conditioning unit 100 and the natural gas wall-mounted boiler 200 can be reasonably matched for use, overall energy consumption is reduced, and overall economic benefit is improved.

To solve this technical problem, it may be realized by adding a new energy heating module 300. In an embodiment, the new energy heating module 300 is further connected to the outdoor unit 101 through a fifth refrigerant pipeline, wherein the new energy heating module 300 is configured to heat and defrost the outdoor unit 101 by using third heat energy through the fifth refrigerant pipeline.

In comparison with the existing defrosting mode of the outdoor unit 101, in this embodiment, the new energy heating module 300 is only required to convert the new energy into the third heat energy, and then the third heat energy is supplied to the outdoor unit 101 through the fifth refrigerant pipeline to perform heating defrosting. Therefore, energy consumption is not required to be increased, so that the air conditioner heating is free from a blank period, and the thermal comfort of a user is improved.

Further, the new energy heating module 300 may be used not only for defrosting the outdoor unit 101, but also for directly preparing hot water instead of part or all of the functions of the outdoor unit 101.

Therefore, on the premise of ensuring the demands of users, the natural gas can be used for hot water preparation and indoor heating as much as possible, so that the economic benefit is improved.

In an example, in most areas in the north, natural gas and electricity fees are priced in a stepped pricing manner, and the electricity fees and natural gas fees change in a fluctuation manner is inconsistent, and the specific change fluctuation situation is related to the area. The electric charge and the natural gas charge are converted into the electric charge/natural gas charge for heating 1 square water from normal temperature to 60 ℃, and the electric charge and the natural gas charge are different along with the gradient relation of the change of the consumption, so that the natural gas is used for preparing hot water in a consumption interval, the natural gas is used for heating water in the interval to save money, and the air conditioner is directly used for heating water outside the interval to save cost. The specific control logic is as follows: comparing the local electric charge and the initial price of natural gas charge, and if the electric charge is lower, controlling a valve in a natural gas meter box, and not using or reducing using natural gas; when the total amount of electricity consumption is increased and the electricity price reaches a level higher than the price of natural gas, the gate of the natural gas pipeline is opened, and natural gas heating is used as the energy source main force for preparing hot water. The control operation strategy is shown in fig. 8.

The specific implementation mode is as follows: and calculating electric quantity and gas consumption nodes corresponding to the electric quantity and gas consumption node converted price changes of the electric quantity and the gas consumption according to the local electric quantity and gas consumption stepped price list, monitoring the electric quantity and the gas consumption in real time by a circuit total gate ammeter and a gas meter, inputting information into a monitoring module of the system according to the scheme, and judging and comparing the current prices of the electric quantity and the gas consumption according to the preset electric quantity and gas consumption nodes.

In the non-overcast and rainy days in the daytime, the system can fully utilize solar energy to heat tap water, raise the initial temperature of the tap water, reduce the whole energy consumption of the system, and save more energy and money. The specific implementation is as follows: when the sun exists in the daytime, the electromagnetic valve 1.6 is controlled to be opened, tap water enters the solar heat exchange module to absorb heat and is stored in the water storage tank, and a user needs to open the magnetic valve 1.8 for the user to directly use or use after heating through the wall hanging stove. In the evening or in rainy days, the electromagnetic valve 1.6 is disconnected to prevent the solar heat exchange module from being frozen.

If the price of electricity charge is higher, the control module outputs signals to the electromagnetic valves 1.3, 1.7, 1.5 and 1.4, wherein the electromagnetic valve 1.3 is closed (can be moderately opened according to actual demands), the electromagnetic valve 1.4 is opened according to actual water consumption of the geothermal hot water circulation, the electromagnetic valves 1.5 and 1.7 are opened, the natural gas is preferentially utilized to prepare hot water at the moment, the electromagnetic valve 1.4 is used for geothermal water supplementing, and the hot water generated by the hot water generator does not enter the wall-mounted furnace and directly flows into the geothermal coil, as shown in fig. 6.

When the hot water demand is large and the natural gas supply is insufficient, the electromagnetic valve 1.3 can be properly opened, the opening degree of the electromagnetic valve 1.4 is increased, at the moment, the hot water of the hot water generator and tap water are mixed and enter the wall hanging stove to be heated by the natural gas, the natural gas consumption is saved, and the wall hanging stove is shown in fig. 6, and at the moment, the wall hanging stove takes natural gas heating as a main body.

If the price of the natural gas is high, the hot water generator is preferentially utilized to prepare hot water, the electromagnetic valve 1.7 is closed, the electromagnetic valves 1.3, 1.4 and 1.5 are opened, tap water does not directly enter the wall-mounted furnace, and the tap water enters the wall-mounted furnace after being heated by the hot water generator, so that the natural gas is saved, and the use of the natural gas is shown in fig. 3. When the hot water demand is large, the electromagnetic valve 1.7 can be properly opened, tap water is introduced to be mixed with hot water of the hot water generator and then enters the wall-mounted boiler to be heated, so that the burden of an air conditioning system is reduced, and the air conditioning system is mainly heated as shown in fig. 6.

Therefore, the air conditioner operation mode can be adjusted according to the energy consumption, so that the economical and optimal operation is achieved, and meanwhile, the hot water two-in-one air conditioner system connected with the solar module is provided, and solar energy can be utilized for heating, hot water production and defrosting, so that the purposes of saving energy and improving economic benefit are achieved.
