Description

[0001] The present application belongs to the technical field of air conditioners, and specifically relates to a heat exchange component and a control method thereof, and an air conditioner. Background Art

[0002] At present, the fan coil water system with one supply pipe and one return pipe is called a double water pipe system, which is similar to the mechanical circulation hot water heating system. It supplies cold water in summer and hot water in winter. At this time, the fan coil has a single structure, the coil flow path form and flow path number are relatively uniform, and the cooling capacity of the unit is mainly solved by the water flow.

[0003] However, the water flow of the fan coil cannot be infinitely small or infinitely large. If the water flow is too small, the resistance of the fan coil will be too large, and the water flow will be too large, which will require a high structure and strength of the unit. Therefore, the water flow of the unit is adjusted within a small range, so the adjustment range of the cooling capacity is also small. When the heating and cooling capacities of the hot water coil and the cooling coil do not overlap, most practices are to set two coils (hot water coil and cold water coil) in one unit, cooling in summer and heating in winter. This method increases the production and maintenance costs of one coil.

[0055] The present application also discloses some embodiments, wherein the heat exchange component further comprises a regulating valve, which is used to adjust the flow of the heat exchange medium passing through the supply pipe according to the required cooling or heating after adjusting the opening number of the inlet 11.

[0056] See also Figure 4-7 As shown, the fan coil unit of the present application is mainly composed of an air release valve 53, a surface cooler 5, a connecting plate 52, a drain bolt 51, an inlet pipe 1 assembly, a coil assembly, and an outlet pipe 3 assembly.

[0059] The present application also discloses some embodiments in which the adjustment portion 12 is movable to open or close part or all of the outlets.

[0060] The present application also discloses some embodiments, in which the size of each inlet 11 is the same, and the size of each adjustment hole is the same as the size of the inlet 11. This makes the maximum flow rate entering each inlet 11 consistent, which is convenient for heat exchange control.

[0061] According to an embodiment of the present application, an air conditioner is provided, comprising a heat exchange component, wherein the heat exchange component is the above-mentioned heat exchange component.

[0062] According to an embodiment of the present application, a control method for the above-mentioned heat exchange component is provided, comprising the following steps:

[0063] Get the indoor temperature T;

[0064] The opening number of the inlet 11 is adjusted according to the indoor temperature T.

[0065] A temperature sensor is set indoors. The temperature and humidity sensor can be used to achieve feedback on temperature. This application can adjust the opening degree of the fan coil according to the indoor temperature feedback and the indoor working conditions, that is, control the number of flow paths of the fan coil, and then adjust the cooling capacity or heating capacity.

[0066] This application also discloses some embodiments. The steps for adjusting the opening number of the inlet 11 according to the indoor temperature T are as follows:

[0067] When T < T1, reduce the opening number of the inlet 11;

[0068] And / or, when T > T1, increase the opening number of the inlet 11; where T1 is a preset temperature. The temperature sensor detects the indoor temperature. The indoor temperature must meet the condition that 0 cooling capacity < the current indoor temperature T ≤ the maximum temperature. First, determine the range of the required cooling capacity through the signal feedback by the temperature sensor, then rotate the regulating pipe to reduce the number of flow paths of the fan coil to the corresponding cooling capacity range value, and then judge whether the current temperature > the predetermined temperature, and increase (decrease) the flow rate of the heat exchange medium to achieve precise temperature control and make the temperature reach the set temperature value.

[0069] This application also discloses some embodiments. The steps for adjusting the opening number of the inlet 11 according to the indoor temperature T are as follows:

[0070] Obtain the required cooling capacity or heating capacity kz according to the indoor temperature T;

[0071] Adjust the opening number of the inlet 11 according to the required cooling capacity or heating capacity kz and the supply cooling capacity or heating capacity corresponding to the opening number of the inlet 11. So that the cooling capacity or heating capacity provided by the opened number of inlets 11 can meet the requirements.

[0072] This application also discloses some embodiments. The control method of the heat exchange component further includes the following steps: after adjusting the opening number of the inlet 11 according to the indoor temperature T, adjust the flow rate of the heat exchange medium in the inlet pipe 1 according to the required cooling capacity or heating capacity kz.

[0073] This application also discloses some embodiments. The steps for adjusting the flow rate of the heat exchange medium in the inlet pipe 1 according to the required cooling capacity or heating capacity kz are as follows:

[0074] When k1 < kz < k2, adjust to open two inlets 11; and reduce the flow rate of the heat exchange medium in the inlet pipe 1;

[0075] Among them, when the number of inlets 11 opened is one, the maximum cooling or heat supplied by the fan coil is K1, and when the number of inlets 11 opened is two, the maximum cooling or heat supplied by the fan coil is K2. Three inlets 11 are opened on the inlet pipe 1, and each inlet 11 is connected to the flow supply pipe 2. Then the fan coil is a three-speed fan coil. Three range values ​​can be set: 0-1 / 3, 1 / 3-2 / 3, and 2 / 3-3 / 3. When the indoor temperature is close to one of the ranges, first adjust the number of flow paths of the fan coil to change the cooling capacity, and then adjust the cooling capacity accurately by adjusting the flow of the heat exchange medium to ensure a constant temperature in the unit.

[0076] When all the flow paths are open, that is, when the regulating tube is in the fully open position, the three inlets 11 are opened, and the flow rate of the unit is fixed. At this time, it is the maximum cooling capacity or heating capacity of the coil. It is equivalent to the cooling capacity or heating capacity of the coil having three gears, namely the maximum cooling capacity or heating capacity, 2 / 3 of the maximum cooling capacity or heating capacity, and 1 / 3 of the maximum cooling capacity or heating capacity. When the current temperature is greater than the predetermined temperature, the cooling capacity or heating capacity is changed by rotating the inner nested copper tubes to increase the number of flow paths, and then the flow rate of each flow path is controlled to achieve precise control of the target. When the current temperature is less than the predetermined temperature, the cooling capacity or heating capacity is changed by rotating the copper tubes to reduce the number of flow paths, and then the flow rate of each flow path is controlled to achieve precise control of the target. For example: the maximum cooling capacity or heating capacity of the coil is 30Kw / h, the cooling capacity or heating capacity of the 2 / 3 circuit is 20Kw / h, and the cooling capacity or heating capacity of 1 / 3 is 10Kw / h. Under the original working condition, the required cooling or heating capacity is 12. At this time, the number of flow paths of the coil is 1 / 3, and then the flow rate of the heat exchange medium is controlled to achieve a cooling or heating capacity of 12. If the working condition changes suddenly and the required cooling or heating capacity changes to 19, you can first adjust the number of flow paths of the unit to 2 / 3, and the cooling or heating capacity reaches 20, and then adjust the heat exchange medium flow rate to adjust the cooling or heating capacity of the unit to 19.

[0077] The control method of the heat exchange component is specifically as follows:

[0078] Detect the indoor temperature and determine the required cooling or heating capacity based on the indoor temperature;

[0079] Determine whether the required cooling or heating capacity is between 1 / 3 of the maximum cooling or heating capacity and the full cooling or heating capacity;

[0080] When the required cooling capacity or heating capacity is between 1 / 3 of the maximum cooling capacity or heating capacity and the fully opened cooling capacity or heating capacity, it is determined whether the required cooling capacity or heating capacity is between 2 / 3 of the maximum cooling capacity or heating capacity and the fully opened cooling capacity or heating capacity;

[0081] If the required cooling or heating capacity is between 2 / 3 of the maximum cooling or heating capacity and the fully open cooling or heating capacity, the fully open mode is still used; then the relationship between the indoor temperature and the preset temperature is judged. If the indoor temperature is greater than the preset temperature during cooling or less than the preset temperature during heating, the water flow in the pipe is reduced;

[0082] If the required cooling capacity or heating capacity is not between 2 / 3 of the maximum cooling capacity or heating capacity and the fully open cooling capacity or heating capacity, determine whether the required cooling capacity or heating capacity is between 1 / 3 of the maximum cooling capacity or heating capacity and 2 / 3 of the maximum cooling capacity or heating capacity;

[0083] If "yes", the double-open mode is adopted; then the relationship between the indoor temperature and the preset temperature is judged. If the indoor temperature is higher than the preset temperature during cooling or lower than the preset temperature during heating, the water flow in the pipe is reduced;

[0084] If "No", the single opening mode is adopted, and then the relationship between the indoor temperature and the preset temperature is judged. If the indoor temperature is higher than the preset temperature during cooling or lower than the preset temperature during heating, the water flow in the pipe is reduced.

[0085] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0086] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above are only preferred implementations of the present application.
