Embodiment 1

[0056] Embodiment 1. The embodiment of the present invention provides a multi-connection system 10, such as figure 1 It includes: an external controller 1010, at least one connection controller 1020 connected to the external controller 1010, an air handler 1030 connected to the connection controller 1020, at least one outdoor unit 1040 and at least one throttling device 1050; The device 1050 is disposed between the outdoor unit 1040 and the air handler 1030 .

[0057] The external controller 1010 is used to obtain adjustment parameters and send the adjustment parameters to the connection controller 1020 .

[0058] The connection controller 1020 is used to collect the first operating parameter of the outdoor unit 1040 and the second operating parameter of the air handler 1030, and generate a set of parameters for the outdoor unit 1040 and the throttling device 1050 according to the adjustment parameter, the first operating parameter and the second operating parameter. , and th...

Embodiment 2

[0064] Embodiment 2. The embodiment of the present invention provides a multi-connection system 10, such as figure 2 Shown include:

[0065] An external controller 1010, at least one connection controller 1020 connected to the external controller 1010, an air handler 1030 connected to the connection controller 1020, at least one outdoor unit 1040, and at least one throttling device 1050; the throttling device 1050 is arranged on Between the outdoor unit 1040 and the air handler 1030 .

[0066] It should be noted that the throttling device may be an electronic expansion valve or an electronic expansion valve group; the air handler 1030 may be a direct expansion air handler.

[0067] The external controller 1010 is used to obtain adjustment parameters and send the adjustment parameters to the connection controller 1020 .

[0068] The connection controller 1020 is used to collect the first operating parameter of the outdoor unit 1040 and the second operating parameter of the a...

Embodiment 3

[0075] Embodiment 3. The embodiment of the present invention provides a multi-connection system 10, such as image 3 , Figure 4 , Figure 5 and Figure 6 The specific implementation is as follows:

[0076] It should be noted that since the multi-connection system includes N connection controllers, here the first connection controller and the second connection controller are represented by the first connection controller and the second connection controller; since the multi-connection system includes 2N throttling devices, where the first throttling device, the second throttling device, the third throttling device and the fourth throttling device use the first throttling device, the second throttling device, the third throttling device, the third throttling device The four throttling devices are expressed by analogy; since the air handler contains 2N heat exchangers, here the first heat exchanger, the second heat exchanger, the third heat exchanger and the fourth heat excha...

Abstract

The invention provides a multi-connection control system, relates to the technical field of air conditioning, and solves the problem in the prior art that a traditional AHU and a multi-connection product cannot be matched with each other when used simultaneously. The system includes an external controller, at least one connection controller connected to the external controller, an air handler connected to the connection controller, an outdoor unit and at least one throttling device; the throttling device is arranged between the outdoor unit and the air handler Between, the outdoor unit contains at least one outdoor unit. The embodiment of the present invention is used for connection control of a multi-line system.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a multi-connected control system. Background technique [0002] Multi-split products are more and more widely used due to their advantages of energy saving, environmental protection, and convenient installation and use. Many buildings, especially some commercial office buildings, use multi-split products as the preferred air conditioning solution. However, in these buildings, there are inevitably some large spaces, halls and meeting rooms with high air quality requirements, and it is better to use air handling units (English full name: Air Handling Unit, AHU) in these places. Air Conditioning Program. [0003] As a widely used heating, ventilation and air conditioning (English full name: Heating, Ventilation and Air Conditioning, HVAC for short) terminal equipment, AHU has rich functions, flexible combination, wide air volume / static pressure range, combined with air ene...
