Referring to fig. 1 and 2 in combination, according to an embodiment of the present invention, there is provided an air conditioner terminal device including: the casing, the casing has the air intake, is provided with water collector 1, surface cooler 2, water pump 3 and watering subassembly 4 in the casing, and surface cooler 2 installs in water collector 1, and water pump 3 can be with the comdenstion water pump that collects in the water collector 1 to watering subassembly 4 so that watering subassembly 4 spill rivers, and the air current that gets into by the air intake flows through rivers, surface cooler 2 in proper order.
In this technical scheme, through the comdenstion water that makes the heat transfer in-process of surface cooler 2 produce with the help of water pump 3 and watering subassembly 4 forms rivers between air intake and surface cooler 2, when the air current that the air intake got into passes rivers, the rivers will play the dust removal effect to the air current, guarantee the cleanliness factor of air to need not to install the airstrainer in the air intake department additionally, and then solved the frequent dismantlement of airstrainer and wash, consume the problem of great manpower and materials.
It should be noted that, the air flow entering from the air inlet can be outdoor fresh air or indoor return air. The water sprayed by the water spraying component 4 falls back into the water receiving disc 1, so that the condensed water can be recycled. It should be noted that, the water flow sprayed by the water spraying component 4 may be a plurality of small water flows, each water flow is distributed at intervals along the width direction of the air inlet, and the interval between two adjacent water flows is smaller; or, the water flow sprayed by the water spraying assembly 4 can be a thinner water curtain, and the water curtain has better dust removal effect on air although the resistance to the formation of air inlet is larger. Further, in order to ensure that the air flow entering from the air inlet completely passes through the water flow sprayed out by the water spraying assembly 4, an air guiding structure with an air duct can be arranged in the shell, one end of the air duct is connected with the air inlet, and the other end of the air duct is led to the sprayed water flow.
Referring to fig. 2, a water blocking part 11 is arranged on one side of the surface cooler 2, which is away from the air inlet, and the water blocking part 11 is of a ventilation structure. The water retaining component 11 can prevent the condensed water on the surface cooler 2 from being taken away when the air flow passes through the surface cooler 2, and the condensed water intercepted on the water retaining component 11 finally flows into the water receiving disc 1.
As shown in fig. 1, a spraying assembly 5 is further arranged in the shell, the water pump 3 can pump condensed water collected in the water receiving disc 1 to the spraying assembly 5, and water flow sprayed by the spraying assembly 5 is used for cleaning the surface cooler 2.
In this embodiment, after the device is used for a long time, dust is deposited on the fins of the surface cooler 2, which reduces the surface heat transfer coefficient of the surface cooler 2 and affects the heat exchange efficiency. After the spray assembly 5 is arranged, the surface cooler 2 can be cleaned regularly, the surface cooler 2 is ensured to have a good heat exchange effect, and meanwhile, compared with manual cleaning in the prior art, the automatic cleaning device has the advantages that the surface cooler 2 is not required to be disassembled, and the automatic cleaning device is more convenient and labor-saving. Wherein, spray assembly 5 includes washs the pipeline and sets up a plurality of shower nozzles on wasing the pipeline, and each shower nozzle sets up along the extending direction interval of wasing the pipeline, and a plurality of each spouts can ensure that the rivers that spray assembly 5 sprayed cover the whole width direction of surface cooler 2.
Referring to fig. 1, a first control valve 6 is arranged on a flow path between the water pump 3 and the spray assembly 5, the first control valve 6 and the spray assembly 5 form a first branch, a second branch is formed on the flow path where the spray assembly 4 is located, and the first branch is connected in parallel with the second branch.
In this technical scheme, because the water flow sprayed out of the spray assembly 5 needs to clean the surface cooler 2, the surface cooler 2 has a strong impact force, if the unit is in a normal working mode to clean the surface cooler 2, the water flow sprayed out of the spray assembly 5 is likely to break through the water retaining component 11 by wind force, and even may be brought out of the air outlet of the device. For safety reasons, it is necessary to arrange the sprinkler assembly 4 and the spray assembly 5 in parallel and to arrange a first control valve 6 upstream of the spray assembly 5. When the unit operates in a normal mode, namely when the air inlet is dedusted through water flow, the first control valve 6 is controlled to cut off circulation, the spraying assembly 5 does not work, and the sprinkling assembly 4 is in a working state; when the surface cooler 2 needs to be cleaned, the unit is stopped, the first control valve 6 is controlled to be opened for circulation, and then the spray assembly 5 enters a working state.
As a specific embodiment, when the spray assembly 5 is in the working state, the unit is stopped, no air is supplied at this time, and the water flow pumped by the water pump 3 is split to prevent the sprinkler assembly 4 from sprinkling, so as to influence the impact force and the water flow of the water flow sprayed by the spray assembly 5, a second control valve 7 is arranged on the second branch, and the second control valve 7 is positioned upstream of the sprinkler assembly 4. When the unit is stopped and the surface cooler 2 is cleaned, the spraying assembly 5 can be in a working state, and the water spraying assembly 4 does not work, so that the diversion is prevented by controlling the first control valve 6 to be opened and the second control valve 7 to cut off the circulation.
Specifically, be provided with the three-way valve on the low reaches flow path of water pump 3, the three-way valve has first port, second port and third port, and first port communicates to spray assembly 5, and the second port communicates to watering assembly 4, and the third port communicates to water pump 3.
In this embodiment, it is also possible to control whether the sprinkler assembly 4 or the sprinkler assembly 5 is operated separately by using a three-way valve. For example, when the unit is stopped and the surface cooler 2 is cleaned, the first port and the third port of the three-way valve are controlled to be communicated, the spraying assembly 5 is in an operating state, and the sprinkling assembly 4 does not operate; when the unit normally operates, the second port and the third port of the control three-way valve are communicated, the spraying assembly 5 does not work, and the sprinkling assembly 4 is in a working state.
Referring to fig. 1, a water treatment instrument 8 is arranged on a flow path between the water pump 3 and the water receiving disc 1; and/or a filter 9 is also arranged on the flow path between the water pump 3 and the water pan 1.
Preferably, the filter 9 is located on the flow path between the water treatment instrument 8 and the water receiving disc 1, so that obvious impurities in the condensed water can be filtered firstly, and then the condensed water is subjected to further descaling treatment by the water treatment instrument 8, so that clean condensed water flows into the sprinkler assembly 4 or the sprinkler assembly 5, corrosion of the condensed water to the sprinkler assembly 4 and the sprinkler assembly 5 is weakened, and the service lives of the sprinkler assembly 4 and the sprinkler assembly 5 are prolonged. Wherein, the impurity in water contains the comdenstion water and removes dust etc. in the air when the air inlet is carried out the dust.
As a specific embodiment, a third branch is provided in the flow path between the water pump 3 and the water pan 1, and a third control valve 10 is provided in the third branch.
In this embodiment, when the condensed water forms water flow to remove dust from the air flow entering from the air inlet, the condensed water will circulate among the water receiving disc 1, the water pump 3 and the water spraying assembly 4, and the surface cooler 2 will generate condensed water continuously to flow into the water receiving disc 1, which will lead to the water level in the water receiving disc 1 rising continuously. In order to prevent the overflow of the condensed water in the water receiving disc 1, when the sprinkler assembly 4 is in the working state, the third control valve 10 is always opened for circulation, so that the water can be drained through the third branch, that is, the arrangement of the third control valve 10 and the third branch can play a role in preventing the overflow of the condensed water in the water receiving disc 1. Preferably, the third branch is located in the flow path between the filter 9 and the drip tray 1, so that the condensate discharged by the third branch does not have to be treated by the filter 9 and the water treatment device 8.
It can be understood that when the unit is in the normal operation mode, the opening of the third control valve 10 is adjusted according to the height of the water level in the water receiving tray 1, and when the height of the water level in the water receiving tray 1 exceeds the set water level line required for forming the dust removing water flow, the opening of the third control valve 10 is increased, and the water amount discharged from the water receiving tray 1 is increased; when the water level in the water receiving disc 1 is lower than the set water level line, the opening of the third control valve 10 is reduced, and the water quantity discharged outwards from the water receiving disc 1 is reduced, so that the required water quantity for forming the dedusting water flow is ensured.
The invention also provides an air conditioner, which comprises the air conditioner tail end equipment. The air conditioner of the application is especially a central air conditioner, and the terminal equipment is a combined cabinet which is similar to a fan coil.
The invention also provides a control method of the air conditioner, which is used for controlling the operation of the air conditioner and comprises the following steps:
an obtaining step, namely obtaining the wind resistance value of the surface cooler 2;
judging and executing, namely controlling the on-off of the first control valve 6 and the second control valve 7 according to the magnitude relation between the wind resistance and the target set value; alternatively, the communication state of each port of the three-way valve is controlled.
In the technical scheme, the wind resistance of the surface air cooler 2 represents the dust accumulation amount on the fins of the surface air cooler 2, so that whether the surface air cooler 2 needs to be cleaned or not can be determined through the magnitude relation between the wind resistance of the surface air cooler 2 and the target set value. The target set value is represented by a wind resistance value corresponding to a wind pressure value borne by the surface of the surface cooler 2, and the wind pressure value can be referred to 100-200Pa.
Specifically, when the wind resistance value is smaller than the target set value, the fact that dust accumulated on fins of the surface air cooler 2 is not much is indicated, and the surface air cooler 2 is not required to be cleaned temporarily, so that the first control valve 6 is controlled to cut off circulation, and the second control valve 7 is controlled to open circulation; or the second port of the three-way valve is controlled to be communicated with the third port, so that the spraying assembly 5 does not work, and the sprinkling assembly 4 is in a working state. Of course, in order to prevent the water pan 1 from overflowing, it is also necessary to control the third control valve 10 to open the circulation.
More specifically, when the wind resistance value is greater than the target set value, it indicates that more dust is accumulated on the fins of the surface air cooler 2, and the surface air cooler 2 needs to be cleaned, so that the first control valve 6 is controlled to open and flow, and the second control valve 7 is controlled to cut off and flow; or the first port and the third port of the three-way valve are controlled to be communicated, so that the spraying assembly 5 is in an operating state, and the sprinkling assembly 4 does not operate. When the wind resistance value is detected to be greater than the target set value, if the condensed water in the water receiving disc 1 does not reach the water level line required for cleaning, the third control valve 10 is controlled to cut off circulation, and the unit is not stopped immediately, but is stopped only after enough condensed water is collected in the water receiving disc 1, and then the surface cooler 2 cleaning step is performed.
