The second purpose of the invention is to provide an air conditioner for realizing the cold air prevention control method of the air conditioner.
A third object of the present invention is to provide a computer-readable storage medium for implementing the above-mentioned air-conditioning cold-air-prevention control method.
In order to achieve the first purpose of the invention, the air-conditioning cold air prevention control method provided by the invention comprises the steps of obtaining the indoor environment temperature and the wind gear of the fan coil indoor unit, and determining the water supply temperature of the fan coil indoor unit according to the indoor environment temperature and the wind gear of the fan coil indoor unit.
According to the scheme, the water supply temperature of the fan coil indoor units is related to the indoor environment temperature and the wind shield of the fan, so that the water supply temperature of each fan coil indoor unit is not fixed and is adjusted according to the current actual condition, and the comfort of a human body can be improved. In addition, the water supply temperature is adjusted according to actual conditions, so that the water supply temperature is more flexible, the condition of heat energy waste caused by setting a fixed water supply temperature is avoided, and the energy-saving performance of the air conditioning system is improved.
Preferably, the temperature of the water supply is directly related to the ambient indoor temperature. Therefore, when the indoor environment temperature is higher, the water supply temperature is also higher, so that the comfort of human body feeling can be improved, and meanwhile, the energy waste can be avoided.
The further proposal is that the water supply temperature is in positive relation with the wind shield of the fan coil indoor unit. Therefore, when the wind shield of the fan coil indoor unit is high, the water supply temperature is high, the fan coil indoor unit can obtain more heat to meet the requirement of high wind shield, and the comfort of a human body is improved.

In a further aspect, the air guide mechanism is configured such that the supply water temperature when the air guide mechanism is in the vertical sweep state is higher than the supply water temperature when the air guide mechanism is in the horizontal blowing state.
When the air guide mechanism blows horizontally, hot air is concentrated, the water supply temperature can be low, and the requirement of energy conservation is met.
The further proposal is that the number of the fan coil indoor units is more than two; determining the water supply temperature of the fan coil indoor unit according to the indoor ambient temperature and the wind shield of the fan coil indoor unit comprises: and determining the water supply temperature of each fan coil indoor unit according to the indoor environment temperature of each fan coil indoor unit and the wind gear of each fan coil indoor unit.

Detailed Description
The air conditioner cold wind prevention control method is applied to a water source heat pump multi-split air conditioner system, the system comprises a host and a plurality of indoor units, preferably, the host is provided with a processor and a memory, the memory stores a computer program, and the processor executes the computer program to realize the air conditioner cold wind prevention control method.
The embodiment of the cold air prevention control method of the air conditioner comprises the following steps:
referring to fig. 2, the air-conditioning cold air prevention control method of the embodiment is applied to a pyrogen water pump multi-split air-conditioning system, which includes a host 30 and a plurality of indoor units, the host 30 is usually disposed outdoors, the plurality of indoor units include fan coil indoor units 31, 33, 35, each fan coil indoor unit is correspondingly provided with a temperature sensor, for example, the fan coil indoor unit 31 is correspondingly provided with a temperature sensor 32, the fan coil indoor unit 33 is correspondingly provided with a temperature sensor 34, the fan coil indoor unit 35 is correspondingly provided with a temperature sensor 36, and each temperature sensor is used for collecting an indoor environment temperature. For example, the plurality of fan coil indoor units 31, 33, 35 are respectively installed in different rooms, and the plurality of temperature sensors 32, 34, 36 respectively collect the ambient temperatures of the plurality of different rooms and transmit the collected ambient temperatures to the host computer 30. In this embodiment, the host 30 and the fan coil indoor units 31, 33, and 35 may be connected by RS485 communication cables, so as to realize data transmission, such as transmission of control signals and transmission of collected temperature data.
The main unit 30 can supply water to a plurality of fan coil indoor units 31, 33, 35, and each fan coil indoor unit 31, 33, 35 has its own control system for controlling its own operation. Thus, when a certain fan coil indoor unit has an operation requirement, namely needs to be started, a signal which needs to be started is sent to the host 30, and the host 30 supplies water to the corresponding fan coil indoor unit.
The required water supply temperature is determined according to the ambient temperature of a room where each fan coil indoor unit is located and the wind shield of each fan coil indoor unit, if each fan coil indoor unit is further provided with an air guide mechanism, the water supply temperature can be determined according to the state of the air guide mechanism, the room temperature where each fan coil indoor unit is located is different, or the wind shields are different, the required water supply temperature is different, the water supply temperature of each fan coil indoor unit can be closer to the use requirement of a user, and the heat supply of each fan coil indoor unit is more comfortable.
The flow of the air conditioner cold air prevention control method will be described with reference to fig. 3. First, step S1 is executed, and the host determines whether any fan coil indoor unit satisfies the startup condition. Specifically, the set temperature corresponding to each fan coil indoor unit is obtained, for example, if the user wants the room temperature to be 28 ℃, the user sends a command of the set temperature through a remote controller or the like, and the fan coil indoor unit determines the set temperature corresponding to the fan coil indoor unit after receiving the command. Meanwhile, a temperature sensor corresponding to the fan coil indoor unit acquires the ambient temperature of a room, whether the set temperature is greater than or equal to the ambient temperature of the room is judged, if the set temperature is less than the ambient temperature of the room, the fact that the fan coil indoor unit does not need to be started is indicated, and the room does not have a heating requirement. If the corresponding set temperature of any one fan coil indoor unit is greater than or equal to the ambient temperature of the room, the fan coil indoor unit has a starting requirement and needs to supply heat to the room, and at the moment, the host needs to supply water to the fan coil indoor unit.
If it is determined in step S1 that any of the fan coil indoor units satisfies the power-on condition, step S2 is executed to obtain the ambient temperature of the room where the fan coil indoor unit is located, for example, the ambient temperature of the environment is obtained by a temperature sensor corresponding to the fan coil indoor unit. Then, step S3 is executed to obtain the current wind level of the fan-coil indoor unit, for example, the current wind level may be an ultrahigh wind level, a high wind level, a medium wind level, a low wind level, and the like.
Next, step S4 is executed to determine whether the fan-coil indoor unit has the air guiding mechanism, for example, by detecting whether there is a connection signal source of the air guiding plate motor, and if so, it is determined that the fan-coil indoor unit has the electric air guiding mechanism, and if yes, it is determined that there is no electric air guiding mechanism, and it is determined that the fan-coil indoor unit can only directly blow hot air from the suspended ceiling during the heating process of the fan-coil indoor unit.
If the fan coil indoor unit is determined not to be provided with the air guide mechanism, step S6 is executed to determine the water supply temperature of the fan coil indoor unit according to the environment temperature and the wind gear of the fan coil indoor unit, preferably, if the indoor environment temperature is higher, the water supply temperature is higher, and if the wind gear is higher, the water supply temperature is higher.
Specifically, if the current indoor temperature is less than 10 ℃, and the wind level set by the user is a low wind level or a medium-low wind level, the water supply temperature of the indoor unit of the fan coil is 26 ℃, if the wind level set by the user is a medium wind level or a medium-high wind level, the water supply temperature of the indoor unit of the fan coil is 28 ℃, and if the wind level set by the user is a high wind level or an ultrahigh wind level, the water supply temperature of the indoor unit of the fan coil is 32 ℃.
If the current indoor temperature is more than or equal to 10 ℃ and less than or equal to 20 ℃, when the wind gear set by the user is low wind gear or medium-low wind gear, the water supply temperature of the fan coil indoor unit is 28 ℃, if the wind gear set by the user is medium wind gear or medium-high wind gear, the water supply temperature of the fan coil indoor unit is 29 ℃, and if the wind gear set by the user is high wind gear or ultrahigh wind gear, the water supply temperature of the fan coil indoor unit is 32 ℃.
If the current indoor temperature is more than 20 ℃ and the wind gear set by the user is a low wind gear or a medium-low wind gear, the water supply temperature of the fan coil indoor unit is 30 ℃, if the wind gear set by the user is a medium wind gear or a medium-high wind gear, the water supply temperature of the fan coil indoor unit is 31 ℃, and if the wind gear set by the user is a high wind gear or an ultrahigh wind gear, the water supply temperature of the fan coil indoor unit is 32 ℃.
Specifically, the following table shows more intuitively the difference in the supply water temperature under different indoor temperatures and different wind levels.
TABLE 1
If the fan coil indoor unit is provided with the air guide mechanism, step S5 is executed to determine the water supply temperature of the fan coil indoor unit according to the ambient temperature, the wind gear of the fan coil indoor unit and the state of the air guide mechanism, preferably, if the indoor ambient temperature is higher, the water supply temperature is also higher, if the wind gear is higher, the water supply temperature is also higher, if the air guide mechanism is in a state of blowing up and down, namely, if the air guide mechanism is in a state of blowing horizontally, namely, the wind sweeping up and down is not executed, the water supply temperature is lower.
Specifically, if the air guide mechanism is in a flat blowing state, water is supplied according to the water supply temperature in table 1, if the air guide mechanism is in an up-and-down blowing state, 2 ℃ is added on the basis of the water supply temperature in table 1, for example, if the current indoor temperature is less than 10 ℃, and the user sets the wind level to be a low wind level or a medium-and-low wind level, if the air guide mechanism is in a flat blowing state, the water supply temperature of the indoor unit of the fan coil is 26 ℃, if the air guide mechanism is in an up-and-down blowing state, the water supply temperature of the indoor unit of the fan coil is 28 ℃, and so on.
Therefore, in the embodiment, the water supply temperature of each fan coil indoor unit is determined in a sectional and multi-condition coupling mode, so that the comfort requirement of human body heating and air supply is considered, and the excellent characteristic of small temperature difference heat exchange of the air conditioning system is greatly exerted. Specifically, the method can be embodied from the following three aspects: firstly, when the indoor temperature is higher and in a low wind gear state, the water supply temperature is higher, the indoor temperature is lower and in a low wind gear state, the water supply temperature is lower, and the air supply ensures that the comfort feeling of a human body is better; secondly, different operating wind gears correspond to different water supply temperatures; thirdly, the water supply temperature is corrected in the presence of the air guide mechanism, that is, the water supply temperature is increased by 2 ℃ when the air guide mechanism is swept up and down, compared with the case of no air guide mechanism or the case of flat blowing by the air guide mechanism.
After the water supply temperature to the fan coil indoor units is determined, the host computer starts to heat the water and conveys the heated water to each fan coil indoor unit. Of course, the ambient temperatures of the rooms in which the fan coil indoor units are located are not always the same, the wind shields of the fan coil indoor units are likely to be different, and the states of the wind guide mechanisms are different, so that the water supply temperatures required by the fan coil indoor units are not completely the same. In this case, the main unit may heat water based on an average value of water supply temperatures to the plurality of fan coil indoor units. For example, the water supply temperatures corresponding to three fan coil indoor units in an air conditioning system are 26 ℃, 28 ℃ and 29 ℃, respectively, and the target temperature of the host heating water is the average value of the water supply temperatures corresponding to the three fan coil indoor units, namely 27.7 ℃.
After the target temperature of the water heated by the host is determined, the host executes step S7, and starts and operates for a first preset time, for example, the host operates for 5 minutes, and the host gradually heats the water within 5 minutes of the host operation, but the water is not heated to the target temperature and therefore does not supply water to each fan coil indoor unit, and at this time, each fan coil indoor unit is not started. After the first preset time, executing step S8, and judging whether the water temperature heated by the host reaches the target water temperature, if so, supplying water to the fan coil indoor unit needing to be opened by the host.
After the fan coil indoor unit receives the water supply, step S9 is executed to operate at the target wind level, for example, if the wind level set by the user is a medium-high wind level, the fan coil indoor unit operates at a medium-high wind level. Since the temperature of the water supplied by the main unit is not the water supply temperature required by the fan coil indoor unit, for example, the target temperature of the water supplied by the main unit is 27.7 ℃, and the current water supply temperature of the fan coil indoor unit is 29 ℃, the fan coil indoor unit also needs to heat the water, for example, a heat source is arranged in the fan coil indoor unit to heat the water, and the heating temperature is the water supply temperature, namely 29 ℃.
Of course, if the temperature of the water supply required by the fan coil indoor unit is lower than the temperature of the water supplied by the main unit, the water can be cooled to meet the requirement of the water supply temperature.
If the water temperature heated by the host does not reach the target water temperature after the first preset time, step S10 is executed, the fan coil indoor unit is turned on and runs at a low wind level for a second preset time, for example, runs for 3 minutes, and then runs at the target wind level, so that when the water temperature provided by the host to the fan coil indoor unit is low, the fan coil indoor unit is not turned on for a long time but turned on after the first preset time, and runs at the highest wind level instead of the highest wind level under the condition of low water temperature, thereby avoiding the influence on human comfort caused by insufficient heat during high wind level running. Therefore, through the step S10, on one hand, the influence on the user caused by the fact that the indoor unit of the fan coil is not opened for a long time can be avoided, and on the other hand, the comfort of the human body can be improved.
Optionally, when the water supply temperatures of the plurality of fan coil indoor units are not consistent, the host machine uses the lowest one of the water supply temperatures of the plurality of fan coil indoor units as the target water temperature, for example, the water supply temperatures corresponding to the three fan coil indoor units are 26 ℃, 28 ℃ and 29 ℃, and the target temperature for heating water by the host machine is the lowest one of the water supply temperatures corresponding to the three fan coil indoor units, namely 26 ℃. Thus, after the host machine supplies water to the plurality of fan coil indoor units, each fan coil indoor unit further heats the water as required, thereby meeting the requirement of heating.
