Description
Technical Field
The application relates to the technical field of intelligent equipment, in particular to an air conditioner and a method and a device for controlling dehumidification of the air conditioner.
Background
In a data center, the relative humidity of the environment is closely related to the normal operation of the server of the data center. According to the standard GB 50174 which requires the most authoritative environment of the domestic data center at present and 2017 electronic information system machine room design specifications, the environmental requirements of different machine room levels are specified: a level/B level, the relative humidity of the main machine room is 40-55% (when starting up), 40-70% (when stopping down); and C level, the relative humidity of the main computer room is 35-75% (during starting up) and 20-80% (during shutdown). When the relative humidity of air is more than 65%, a layer of water film with the thickness of 0.001-0.01 microns is attached to the surface of an object, the humidity is 100%, and the water film easily causes 'conductive short circuit' or flashover, so that the reliability of a circuit is seriously reduced.
Therefore, for the server, whether the precision air conditioner has the humidity control function or not is of great significance to the normal use of data center products. Therefore, in a traditional data center room, in order to avoid overhigh humidity, dehumidification is generally performed by using the air reduction amount. However, when the load of the cabinet is small, when the cabinet is opened for dehumidification, the compressor still refrigerates, after the air volume is reduced, the outlet air temperature is lower, which can cause the temperature of the refrigeration channel to drop very quickly, the compressor is frequently started and stopped, and the dehumidification effect is not good, so that the dehumidification temperature compensation is needed.
At present, the accessible electrical heating dehumidifies temperature compensation, and like this, can be so that the temperature of cold passageway is unlikely to the too fast that descends through electrical heating, and then prolongs compressor opening time, promotes dehumidification effect, but starts electrical heating and has caused certain energy extravagant to, through consuming electrical heating's energy, offset some refrigerating capacity, although promote the temperature, nevertheless also prolong dehumidification time.

Fig. 1 is a schematic structural diagram of an air conditioner provided in an embodiment of the present disclosure. As shown in fig. 1, the air conditioner includes: a compressor 1, a condenser 2, an expansion valve 3, an evaporator 4, and a reheater 5.
The connections of the compressor 1, the condenser 2, the expansion valve 3, and the evaporator 4 are not changed, but a reheater 5 is added to the air conditioner. A first end of the reheater 5 is connected to a first pipeline between the compressor 1 and the condenser 2 through an electromagnetic valve 6; and a second end of the reheater 5 is connected to a second line between the compressor 1 and the evaporator 4.
In this way, when the air conditioner is in the dehumidification state and there is a temperature compensation requirement, the solenoid valve 6 can be controlled to open, and the full-open state is adopted, so that a part of the high-temperature gas coming out from the compressor 1 can enter the reheater 5, and the reheater 5 includes heat exchanger elements, such as: the heat exchange copper pipe, like this, high-temperature gas can obtain the gas after the heat transfer after the reheater 5 is released heat to, change a part of high-temperature gas and obtain the cooling gas after condenser 2, expansion valve 3 and evaporimeter 4 cooling, like this, the gas after the heat can mix the back with the cooling gas, gets into the return-air inlet of compressor 1, thereby, has accomplished a gas circuit circulation, so the reciprocating cycle, carries out the operation of dehumidification state.
In the process of opening the electromagnetic valve 6, because the reheater 5 enters the high-temperature gas coming out of the compressor 1, heat exchange can be carried out, heat is released to the space environment, and heat can be brought into a room through the fan, so that the environment temperature and the temperature of a refrigeration channel are improved, the compressor cannot be frequently started and stopped, the dehumidification effect is improved, only the switch of the electromagnetic valve needs to be controlled, electric energy does not need to be consumed for heating, and energy consumption is saved.
Certainly, under the condition that the air conditioner is in a refrigeration state, the port of the electromagnetic valve 6 connected with the reheater can be controlled to be in a closed state, so that high-temperature gas exhausted by the compressor 1 only needs to be throttled by the condenser 2 and the expansion valve 3 to enter the evaporator 4, the evaporator 4 absorbs heat for cooling the space, then the refrigerant is changed into a gas state to return to the compressor, and the operation in the refrigeration state is performed by the reciprocating circulation.
In some embodiments, the solenoid valve may be a two-way solenoid valve, as shown in fig. 1, with one port connected to the first end of the reheater and the other port connected to the first conduit.
In some embodiments, the solenoid valve may be a three-way solenoid valve, each port of the three-way solenoid valve being connected to the compressor, the condenser, and the reheater, respectively.
Fig. 2 is a schematic structural diagram of an air conditioner provided in an embodiment of the present disclosure. As shown in fig. 2, the air conditioner includes: a compressor 1, a condenser 2, an expansion valve 3, an evaporator 4, a reheater 5, and a three-way solenoid valve 7.
A first port of the three-way solenoid valve 7 is connected to an air outlet of the compressor 1, a second port of the three-way solenoid valve 7 is connected to an air inlet of the condenser 2, and a third port of the three-way solenoid valve 3 may be connected to one port of the reheater. Like this, when the air conditioner is in dehumidification state operation, and when there is the demand of temperature compensation, steerable three way solenoid valve 7 is opened, be in full-through state promptly, thereby, the high-temperature gas that comes out from compressor 1 can get into condenser 2 and reheater 5 respectively, and after releasing heat through reheater 5, can obtain the gas after the heat transfer, and after the high-temperature gas passes through condenser 2, expansion valve 3, and evaporimeter 4 cooling, obtain the cooling gas, like this, the gas can mix with the cooling gas after the heat transfer, and get into the return-air inlet of compressor 1, like this, once gas circuit circulation has been accomplished, so to reciprocate the circulation, carry out the operation of dehumidification state.
In this embodiment, open at the in-process that is in the full-through state at three-way solenoid valve 7, because reheater 5 has got into the high-temperature gas that comes out from compressor 1, can carry out the heat transfer, and release heat to the space environment to can bring the heat into the room through the fan, thereby, ambient temperature and refrigeration passageway temperature have been improved, can not cause the compressor to frequently start and stop, have improved dehumidification effect, and, only need the switch of control solenoid valve, need not consume the electric energy and heat, saved the consumption of energy.
Of course, if the air conditioner is in a refrigeration operation state, the third port of the three-way electromagnetic valve 7 may be closed, that is, the port connected to the reheater is in a closed state, so that the high-temperature gas discharged from the compressor 1 only needs to pass through the condenser 2 and the expansion valve 3 to be throttled and enter the evaporator 4, the evaporator 4 absorbs heat to cool the space, and then the refrigerant is changed into a gaseous state to return to the compressor, and the operation in the refrigeration state is performed by such a reciprocating circulation.
In the embodiment of the disclosure, the temperature compensation control of the air conditioner in the dehumidification process is realized through the control of the solenoid valve connected with the reheater.
Fig. 3 is a schematic flowchart of a dehumidification control method for an air conditioner according to an embodiment of the present disclosure. Of course, the air conditioner may be configured as described above, as shown in fig. 3, and the process for the dehumidification control of the air conditioner includes:
step 301: and acquiring the current measured temperature of the air conditioner in the dehumidification operation state.
The air conditioner has a plurality of operation modes including: cooling, heating, dehumidifying, blowing, and the like. In the process of air conditioner operation, the temperature of a plurality of positions can be detected, including: one or more of indoor ambient temperature, outdoor ambient temperature, coil supply temperature, compressor return air port temperature, etc., i.e., measuring the temperature may include: one or more of an indoor ambient temperature, an outdoor ambient temperature, a coil supply air temperature, a compressor return air port temperature, and the like. The air conditioner can monitor the temperature of one, two or more positions at regular time or in real time, and the current measured temperature can be obtained by each detection.
In the embodiment of the present disclosure, modes such as control instruction and mode switching may be performed to enable the air conditioner to be in a dehumidification operation state, and to obtain a current measured temperature of the air conditioner during an operation of the dehumidification state of the air conditioner, where the current measured temperature includes: current indoor ambient temperature, current outdoor ambient temperature, current coil supply temperature, current compressor return air port temperature, and/or the like.
Step 302: under the condition that the current measured temperature is determined to be lower than the corresponding set temperature, the electromagnetic valve connected with the reheater is controlled to be in a full-open state, so that high-temperature gas coming out of the compressor enters the reheater to release heat, heat-exchanged gas is obtained, and the heat-exchanged gas is mixed with cooling gas cooled by the evaporator and enters an air return port of the compressor.
In the case where the air conditioner is operated in the dehumidification state, the temperature of the cooling channel may be rapidly decreased, i.e., temperature compensation is required, and in some embodiments, determining that temperature compensation is required may include: under the condition that the current measured temperature comprises the current indoor environment temperature and the current indoor environment temperature is less than the first set temperature, the temperature compensation can be determined to be needed, and therefore the solenoid valve connected with the reheater can be controlled to be in a full-open state. The first set temperature may be determined based on the target temperature, for example: the first set temperature is equal to the target temperature-2 deg.c, or the first set temperature is equal to the target temperature-3 deg.c. When the air conditioner is operated in a dehumidification state, the temperature of the refrigeration channel is reduced, and the ambient temperature in the front room is also reduced, and when the current ambient temperature in the front room is lower than the first set temperature, the temperature compensation is determined to be needed.
In some embodiments, determining that temperature compensation is needed may include: under the condition that the current measured temperature comprises the current coil air supply temperature and the current coil air supply temperature is less than the second set temperature, the temperature compensation can be determined to be needed, and therefore the electromagnetic valve connected with the reheater can be controlled to be in a full-open state. The temperature of the air supplied by the coil pipe can reflect the temperature of the refrigerating channel, the temperature of the air supplied by the coil pipe can also be reduced when the temperature of the refrigerating channel is reduced, and when the current temperature of the air supplied by the coil pipe is lower than a second set temperature, the temperature of the refrigerating channel is reduced more and is lower, and temperature compensation is needed.
A reheater is added in the air conditioner, a first end of the reheater is connected to a first pipeline between the compressor and the condenser through a solenoid valve, and a second end of the reheater is connected to a second pipeline between the compressor and the evaporator. No matter whether the electromagnetic valve is a two-way electromagnetic valve as shown in fig. 1 or a three-way electromagnetic valve as shown in fig. 2, the electromagnetic valve can be controlled to be in a full-pass state after temperature compensation is determined to be needed, so that high-temperature gas coming out of the compressor 1 can be cooled by the condenser 2, the expansion valve 3 and the evaporator 4 to obtain cooling gas, and the high-temperature gas coming out of the compressor 1 can also enter the reheater 5 to release heat to obtain heat-exchanged gas, and then the heat-exchanged gas can be mixed with the cooling gas to enter a return port of the compressor 1, so that one gas path circulation is completed, and the operation in a dehumidification state is performed by the reciprocating circulation.
It can be seen that, in this embodiment, when it is determined that temperature compensation is required, the control solenoid valve is in a full-open state, and since the reheater enters high-temperature gas coming out of the compressor, heat exchange can be performed, heat is released to a space environment, and heat can be brought into a room through the fan, so that the ambient temperature and the temperature of the refrigeration channel are increased, frequent start and stop of the compressor cannot be caused, the dehumidification effect is improved, and only the on-off of the control solenoid valve is needed, electric energy is not consumed for heating, and energy consumption is saved.
Of course, when the air conditioner is in normal cooling operation, the pipeline connected to the reheater needs to be closed, that is, when the air conditioner is in the cooling operation state, the port of the control solenoid valve connected to the reheater is in a closed state. Therefore, high-temperature gas discharged by the compressor only needs to be throttled by the condenser and the expansion valve to enter the evaporator, the evaporator absorbs heat and cools the space, then the refrigerant is changed into a gas state and returns to the compressor, and the refrigerant is circulated in a reciprocating mode to run in a refrigerating state.
The following operational procedures are integrated into a specific embodiment to illustrate the dehumidification control process for an air conditioner provided by the embodiment of the invention.
In an embodiment of the present disclosure, an air conditioner may be as shown in fig. 1, including: a compressor 1, a condenser 2, an expansion valve 3, an evaporator 4, a reheater 5, and a two-way solenoid valve 6. And the first set temperature is preset to be the target temperature-2 ℃.
Fig. 4 is a schematic flowchart of a dehumidification control method for an air conditioner according to an embodiment of the present disclosure. With reference to fig. 1 and 4, the process for the air conditioning dehumidification control includes:
step 401: is the operation state of the air conditioner judged to be the dehumidifying operation state? If so, go to step 402, otherwise, go to step 406.
Step 402: and acquiring the current indoor environment temperature of the air conditioner in the dehumidification operation state.
Step 403: is it determined whether the current indoor ambient temperature is less than the first set temperature? If yes, go to step 404, otherwise, go to step 405.
Step 404: and controlling the two-way electromagnetic valve to be in a full-on state.
Like this, the high-temperature gas that comes out from compressor 1 not only can get the cooling gas after condenser 2, expansion valve 3 and evaporimeter 4 cooling to, the high-temperature gas that comes out from compressor 1 still can get into reheater 5 and carry out the back of releasing heat, obtains the heat transfer after gaseous, then, the heat transfer after gaseous can mix the back with the cooling gas, gets into compressor 1's return air mouth, like this, has accomplished a gas circuit circulation, so reciprocating cycle, carries out the operation of dehumidification state.
Step 405: and controlling the two-way electromagnetic valve to be in a closed state.
Step 406: is the operation state of the air conditioner judged to be the cooling operation state? If so, go to step 405, otherwise, the process ends.
When the air conditioner operates in a refrigerating mode, high-temperature gas exhausted by the compressor only needs to be throttled by the condenser and the expansion valve to enter the evaporator, the evaporator absorbs heat to cool the space, then the refrigerant is changed into a gas state to return to the compressor, and the refrigerant is circulated in a reciprocating mode to operate in a refrigerating state.
It can be seen that, in this embodiment, in the air conditioning dehumidification operation process, the indoor ambient temperature drops greatly, the refrigeration channel temperature is too low promptly, need carry out temperature compensation, at this moment, can open two-way solenoid valve, make two-way solenoid valve be in the complete open state, because the reheater has got into the high-temperature gas that comes out from the compressor, can carry out the heat transfer, to the space environment heat release, and can bring the heat into the room through the fan, thereby, ambient temperature and refrigeration channel temperature have been improved, can not cause the compressor frequent start-stop, dehumidification effect has been improved, and, only need control the switch of two-way solenoid valve, need not consume the electric energy and heat, energy consumption has been saved.
According to the above-described process for the dehumidification control of the air conditioner, an apparatus for the dehumidification control of the air conditioner can be constructed.
Fig. 5 is a schematic structural diagram of an air conditioning dehumidification control device according to an embodiment of the present disclosure. The air conditioning structure may be as described above, as shown in fig. 5, the dehumidifying control device for air conditioner includes: an acquisition module 510 and a first control module 520.
An obtaining module 510 configured to obtain a current measured temperature of the air conditioner in a dehumidification operation state.
The first control module 520 is configured to control the solenoid valve connected to the reheater to be in a full-open state when it is determined that the current measured temperature is lower than the corresponding set temperature, so that high-temperature gas coming out of the compressor enters the reheater to release heat, heat-exchanged gas is obtained, and the heat-exchanged gas and cooling gas cooled by the evaporator are mixed and enter a return air port of the compressor.
In some embodiments, the first control module 520 is specifically configured as a first control module specifically configured to control a solenoid valve connected to the reheater to be in a full-on state if the current measured temperature includes a current indoor ambient temperature and the current indoor ambient temperature is less than a first set temperature; and under the condition that the current measured temperature comprises the current coil air supply temperature and the current coil air supply temperature is less than the second set temperature, controlling an electromagnetic valve connected with the reheater to be in a full-open state.
