Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0082] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0083] like Figure 1 As shown, a control system for reducing the condensing temperature in a preferred embodiment of the present application includes:

[0084] The collection unit includes multiple collection modules, and the collection unit is used to collect condensed water generated during the air conditioning refrigeration process.

[0085] A storage unit is connected to the collection unit through a pipeline, and the storage unit is used to store the collected condensed water;

[0086] A monitoring module and a drainage pump are provided in the storage unit;

[0087] A spray unit is connected to the storage unit through a pipeline, and the spray unit is used to control the temperature parameters of the condenser;

[0088] The central control unit is used to set the control parameters of the spray unit.

[0089] Specifically, the collection modules are preferably a plurality of condensed water collectors, which are respectively installed at the condensed water discharge ports of the air conditioner. All the collection modules are connected to the storage unit through pipelines, and the storage unit is preferably a water collecting tank, which is provided with a monitoring module and a drainage pump.

[0090] Specifically, the amount of condensed water reaching the spray unit is controlled by starting and stopping the drainage pump. The monitoring module includes a liquid level detection sensor, a temperature sensor and a water quality detection sensor, which are used to obtain the water level height, condensed water temperature and impurity parameters of the condensed water.

[0091] Specifically, the drainage pump transports the condensed water in the storage unit to the condenser through a pipe, and the condensed water is sprayed on the condenser through a nozzle, cooling the condenser by evaporation and convection.

[0092] Specifically, the central control unit includes:

[0093] The first processing module is used to establish a water level monitoring model and set a first water level height A1 and a second water level height A2 according to the water level monitoring model, and A1>A2;

[0094] The second processing module is used to establish a condensate scaling model;

[0095] The third processing module is used to obtain the water level a of the condensed water in the storage unit and set the control mode of the spray unit according to the water level a;

[0096] If a>A1, set the control mode of the spray unit to the primary control mode;

[0097] If a≤A1, the control mode of the spray unit is set to the secondary control mode.

[0098] Specifically, the first water level and the second water level are set according to the different equipment parameters of the storage unit. The first water level is the water level threshold of the condensed water. When the first water level is reached, spraying is required immediately to drain the excess condensed water in the storage unit. The second water level is the safe height of the condensed water, that is, the minimum amount of water for timely spraying and cooling when the temperature of the condenser rises rapidly. By setting the first water level and the second water level, an automated drainage and cooling process is achieved, which improves the operating efficiency and stability of the system.

[0099] It can be understood that in the above embodiment, condensed water is collected by adding a collection unit and a storage unit, and the condensed water generated by the air conditioner itself is used for cooling, without the need for an external water source, thereby simplifying the system structure, improving the cooling efficiency of the condenser, and reducing operating costs.

[0100] Specifically, the first-level control mode includes:

[0101] Obtaining condensed water parameters and impurity parameters in the storage unit;

[0102] Generate the spraying time t according to the impurity parameters and the condensate scaling model;

[0103] Establish a primary spray cycle according to the spray duration t;

[0104] Generate the initial water level a1 and the expected condensate collection rate v in the first-stage spraying cycle;

[0105] Generate a spraying speed interval (B1, B2) based on the initial water level a1, the expected condensed water collection speed v and the spraying time t;

[0106] Among them, B1=[(a1-A1)+t*v] / t; B2=[(a1-A2)+t*v] / t;

[0107] The real-time temperature d of the condenser is obtained, and the spraying speed b1 within the first-level spraying cycle is set according to the real-time temperature d of the condenser.

[0108] Specifically, the first-level control mode means that the amount of condensed water in the current storage unit exceeds the maximum storage value, and it is necessary to spray in time to discharge the condensed water in the storage unit.

[0109] Specifically, the impurity parameters in the condensate water, the fitting function of the spraying time and the scaling probability are established through historical parameters, and the corresponding safe scaling probability is set according to the operating parameters of the condenser, so as to generate the corresponding spraying time according to the real-time impurity parameters and establish the corresponding first-level spraying cycle.

[0110] Specifically, according to the preset heat exchange model and the real-time temperature of the condenser, the corresponding spray speed b1 is adjusted, and a fitting function of the real-time temperature and the spray speed is established to allow the condensed water to evaporate fully, thereby achieving cooling of the condenser on the one hand and avoiding the environmental problem of condensed water flowing everywhere on the other.

[0111] Specifically, the first-level control mode also includes:

[0112] Establish the expected change curve of water level height within the first-level spraying cycle;

[0113] Generate multiple feedback time nodes within the first-level spray cycle;

[0114] Obtain the actual water level height a2 and the expected water level height a2' of the condensed water in the storage unit at the current feedback time node;

[0115] If a2>a2', the water level difference c is generated based on the actual water level a2 and the expected water level a2';

[0116] The spraying speed b1 within the first-level spraying cycle is corrected according to the water level difference c.

[0117] Specifically, the spraying speed is adjusted in time by monitoring the water level difference c, thereby controlling the amount of condensed water in the storage unit and improving the stability of system operation.

[0118] In a preferred embodiment of the present application, the secondary control mode includes:

[0119] A first temperature threshold D1 and a second temperature threshold D2 are preset, and D1<D2

[0120] Get the real-time temperature d of the condenser;

[0121] If the real-time temperature d is less than the first temperature threshold D1, no spraying plan is generated;

[0122] If the real-time temperature d is between the first temperature threshold D1 and the second temperature threshold D2, a first-level spraying plan is generated;

[0123] If the real-time temperature d is greater than the second temperature threshold D2, a secondary spraying plan is generated.

[0124] Specifically, the secondary spray plan means that the current condenser temperature exceeds the safety threshold and needs to be cooled down quickly immediately. The working efficiency of the spray unit is adjusted to the maximum value for spraying operations, so as to control the condenser temperature in time and improve the stability and efficiency of system operation.

[0125] Specifically, when generating a primary sprinkler plan, it includes:

[0126] Obtain the water level a2 of the condensed water in the storage unit, the condensed water temperature, the impurity parameters and the real-time temperature d of the condenser;

[0127] Generate multiple initial spray strategies based on preset heat transfer model and condensate scaling model;

[0128] Generate operational evaluation values ​​for each initial spraying strategy;

[0129] Establish an operation evaluation value sequence H, H = (h1, h2...hn), where hi is the operation evaluation value of the i-th initial spray strategy;

[0130] The initial spraying strategy corresponding to the maximum value hmax in the operation evaluation value sequence H is set as the first-level spraying plan.

[0131] Specifically, intermittent spraying time parameters are generated according to the impurity parameter settings, and the start and stop nodes of multiple drainage pumps are set. At the same time, multiple initial spraying strategies are generated by combining the water level and temperature of the condensed water with the heat exchange model. The spraying speed and start and stop nodes of the drainage pump in a single initial spraying strategy are different.

[0132] Specifically, the evaluation model is established to generate the operation evaluation value of each initial spray strategy. The evaluation indicators for a single initial spray strategy include but are not limited to the condenser temperature value and fluctuation parameters after spraying, the operation cost corresponding to the start and stop frequency of the drainage pump, and other parameters. The larger the operation evaluation value, the higher the feasibility of the corresponding initial spray strategy. The optimization process is used to optimize the primary spray plan.

[0133] It can be understood that in the above embodiment, by monitoring the water level of the condensed water and the real-time temperature of the condenser, multi-level condensed water control parameters are established to achieve dynamic adjustment of the condensed water spraying, improve the cooling efficiency, and intermittent water supply and cooling can reduce the probability of scale generation in the condenser. At the same time, the high-temperature evaporation of the condenser turns the liquid into gas, which solves the environmental problem of condensed water flowing everywhere.

[0135] Establishing a water level monitoring model, and setting a first water level height A1 and a second water level height A2 according to the water level monitoring model;

[0137] If a>A1, set the control mode of the spray unit to the primary control mode;

[0138] If a≤A1, the control mode of the spray unit is set to the secondary control mode.

[0156] If the real-time temperature d is between the first temperature threshold D1 and the second temperature threshold D2, a first-level spraying plan is generated;

[0157] If the real-time temperature d is greater than the second temperature threshold D2, a secondary spraying plan is generated;

[0160] Generate multiple initial spray strategies based on preset heat transfer model and condensate scaling model;

[0161] Generate operational evaluation values ​​for each initial spraying strategy;

[0162] Establish an operation evaluation value sequence H, H = (h1, h2...hn), where hi is the operation evaluation value of the i-th initial spray strategy;

[0163] The initial spraying strategy corresponding to the maximum value hmax in the operation evaluation value sequence H is set as the first-level spraying plan.

[0164] According to the first concept of the present application, condensed water is collected by adding a collection unit and a storage unit, and the condensed water generated by the air conditioner itself is used for cooling. There is no need for an external water source, which simplifies the system structure, improves the cooling efficiency of the condenser, and reduces operating costs.
