Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning systems, in particular to a combined heating control system coordinated between an air-conditioning unit and a wall-mounted boiler. Background Art

[0002] The air conditioner heats the room by absorbing heat from the outdoor environment and releasing it into the room. When the outdoor environment temperature is low, the amount of heat absorbed by the air conditioner from the outdoor environment will also decrease, and the heating effect will become worse. In order to make up for the heating amount, the air conditioner will turn on the auxiliary electric heating device.

[0003] However, the auxiliary electric heating power is relatively small, and the cost of converting electrical energy into thermal energy is expensive. Especially in bad weather, the electric heating module has a low energy efficiency ratio and frequent defrosting causes the energy consumption cost of the air conditioning system to be too high. Utility Model Content

[0004] The utility model aims to solve the problems existing in the prior art and proposes a combined heating control system of an air-conditioning unit and a wall-mounted boiler.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The combined heating control system of an air-conditioning unit and a wall-mounted boiler comprises an air-conditioning unit and a gas wall-mounted boiler, wherein the air-conditioning unit is provided with a water inlet pipe and a water outlet pipe, and the air-conditioning unit is connected in series with the gas wall-mounted boiler via the water outlet pipe.

[0007] Preferably, the water inlet pipe is connected in series with the air-conditioning unit through a liquid flow control system, and the liquid flow control system includes two groups of first valves, filters, first flexible connectors, water pumps, second flexible connectors, check valves and second valves that are connected in sequence, and the input ends of the two groups of first valves are connected through pipelines, and the output ends of the two groups of second valves are connected through pipelines, and the two pipelines are respectively the input end and output end of the liquid flow control system.

[0008] Preferably, the water inlet pipe is also connected to an expansion tank via a pipeline, and a safety valve is provided on the pipeline.

[0009] Preferably, both the output end and the input end of the air conditioning unit are provided with temperature sensors, and the two temperature sensors are respectively provided on the water outlet pipe and the water inlet pipe.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] Since the air conditioning unit is connected to the gas wall-mounted boiler in series through the water outlet pipe, the normal operation can compensate for the lack of heat in the module mechanism; in bad weather, the module energy efficiency ratio is low, and the air conditioning unit can be turned off and the wall-mounted boiler can be used for heating. In low ambient temperature, the air conditioning unit has a low energy efficiency ratio and needs to be defrosted frequently, and using gas is more economical than using electricity, which can well compensate for the problem of insufficient heat in the air conditioning system.

DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0016] Example 1

[0017] Reference Figure 1 The combined heating control system of the air-conditioning unit 1 and the wall-mounted boiler comprises the air-conditioning unit 1 and the gas wall-mounted boiler 2. The air-conditioning unit 1 is provided with a water inlet pipe 3 and a water outlet pipe 4, and the air-conditioning unit 1 is connected in series with the gas wall-mounted boiler 2 through the water outlet pipe 4.

[0018] Among them, the water inlet pipe 3 is used for terminal return water, that is, the cold water flowing back to the boiler room or cooling tower from the terminal equipment such as the air-conditioning unit 1, and the water outlet pipe 4 is used for terminal water inlet, that is, the hot water or cold water transported to the radiator, air-conditioning unit 1 and other terminal equipment.

[0019] When the system is in use, since the air-conditioning unit 1 is connected in series with the gas-fired wall-mounted boiler 2 through the water outlet pipe 4, it can replace the auxiliary electric heating in the prior art in bad weather. When used in a small system, not only is the cost of gas cheap, but the gas-fired wall-mounted boiler 2 has a relatively large power and a high module energy efficiency ratio, which can well compensate for the problem of insufficient heat in the air-conditioning system.

[0020] In this embodiment, the water inlet pipe 3 is connected in series with the air-conditioning unit 1 through a liquid flow control system. The liquid flow control system includes two groups of first valves 5, filters 6, first flexible connectors 7, water pumps 8, second flexible connectors 9, check valves 10 and second valves 11 that are connected in sequence, and the input ends of the two groups of first valves 5 are connected through pipelines, and the output ends of the two groups of second valves 11 are connected through pipelines, and the two pipelines are respectively the input end and output end of the liquid flow control system. By using the above-mentioned liquid flow control system, when one of the paths fails, the first valve 5 and the second valve 11 can be used to close the path, and the other path can be used to work, thereby ensuring that the air-conditioning system can work normally.

[0021] In this embodiment, temperature sensors are provided at both the output and input ends of the air-conditioning unit 1. The two temperature sensors are respectively arranged on the water outlet pipe 4 and the water inlet pipe 3. The temperature sensors are used to detect the water temperature at the output and input ends of the air-conditioning unit 1. In this way, the gas wall-mounted boiler 2 can be automatically controlled to heat the water body according to the temperature through a processor such as a single-chip microcomputer, thereby achieving precise temperature control.

[0022] Embodiment 2, as Figure 2 As shown,

[0023] The difference between this embodiment and embodiment 1 is that:

[0024] In this embodiment, a second pipe 12 is arranged in parallel on the water outlet pipe 4, an auxiliary electric heating device 13 is arranged on the second pipe 12, the gas wall-mounted boiler 2 is located between the two ends of the second pipe 12, the output end and the input end of the gas wall-mounted boiler 2 are both provided with a third valve 14 installed on the water outlet pipe 4, and a fourth valve 15 is arranged at both ends of the second pipe 12. The third valve 14 is located between the two ends of the second pipe 12. An auxiliary electric heating device 13 is connected in parallel at the gas wall-mounted boiler 2. When the gas wall-mounted boiler 2 cannot be used due to gas or other reasons, electric heating can be used to ensure the normal operation of the system.

[0025] In this embodiment, the input end of the liquid flow control system is connected to an energy storage tank 16, and the energy storage tank 16 is connected to the solar collector through a circulation pipeline. The energy storage tank 16 is provided with an automatic air release valve. The energy storage tank 16 stores hot water (hot water is generated by heating the solar collector) or cold water for emergency use or use during peak water usage hours, thereby ensuring the overall stability of the pipeline system.

[0026] In this embodiment, the water inlet pipe 3 is also connected to an expansion water tank 17 through a pipeline, and a safety valve is provided on the pipeline. The expansion tank is used to compensate for the expansion of water volume caused by temperature changes in the system. When the water temperature rises, the water volume will increase. The expansion water tank 17 provides additional space to accommodate this part of the expanded water, thereby preventing the system from being damaged due to overpressure.

[0027] In this embodiment, a gas detection sensor is provided on the gas input pipeline of the gas wall-mounted boiler 2. The gas detection sensor is electrically connected to the third valve 14, the fourth valve 15 and the auxiliary electric heating device 13 through the control processor. When the gas detection sensor detects that there is no gas input, the use of the gas wall-mounted boiler 2 is stopped through the control processor, and the use of the auxiliary electric heating device 13 is automatically controlled.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
