In subsequent description, using for indicating that the suffix of such as " module ", " component " or " unit " of element is only The explanation for being conducive to the present invention, itself does not have a specific meaning.Therefore, " module ", " component " or " unit " can mix Ground uses.

Temperature fluctuation when in order to solve to use water chiller-heater unit to be freezed or heated in the related technology is larger, comfort Relatively low problem, an embodiment of the present invention provides a kind of control methods of multiple water chiller-heater unit, as shown in Figure 1, this method Including：

Step S101, the interior machine capacity of machine group end is determined every the first preset duration；

Step S102, the running frequency of compressor is determined according to interior machine capacity, wherein between running frequency and interior machine capacity With correspondence；

Step S103, control compressor is run according to running frequency.

There is feedback relationship between end and host, host can be controlled according to the case where end.When being determined that interior machine holds When amount, suitable running frequency can be selected according to the correspondence of interior machine capacity and compressor operating frequency, make compressor according to This frequency is run.Heating capacity and refrigerating capacity are adapted with interior machine capacity as a result, to make temperature fluctuation more stablize, are more filled it up with The demand of sufficient user improves the usage experience of user.

In the embodiment of the present invention, multiple water chiller-heater unit is controlled using interior machine (end) by the way of outer machine (host).When After unit is powered, user sets operation required under current environmental temperature on the control panel (for example, air-conditioning remote control) of interior machine The environment temperature that pattern and user need.And wind disk is opened, select wind shelves (for example, high, medium and low, superpower 4 shelves can be divided into Position).The controller of host collects operational mode information, temperature information set by user and the wind disk of booting of interior machine by communicating Quantity information, and be switched on and run according to above- mentioned information.Before step S101, self-check program can also be started；According to self-test journey The testing result of sequence determines that unit can be run.When testing result is that unit breaks down, then startup separator is alarmed, with prompt User's unit needs repairing.

After unit operation, first, according to the principle of internal-external machine capacity matching, regulate and control the running frequency of compressor.It is inside and outside Machine capacity matching principle is the correspondence of the wind disk quantity and interior machine capacity to be had turned on according to end, determines interior machine capacity, Further according to the correspondence of the running frequency of interior machine capacity and compressor, the running frequency of compressor is determined.Specifically applying Property example in, host can calculate the wind disk quantity of current end booting every 30 seconds (the first preset duration), and according to end The wind disk quantity of booting accurately calculates interior machine capacity, and then determines the running frequency of compressor.Wherein, running frequency is gradually to add It carries.As shown in table 1：

Table 1

Assuming that having 16 wind disks (each wind disk corresponds to an interior machine), the pressure that A1, A2 ... A16 are and interior machine capacity matches The original frequency of contracting machine.If currently detected interior machine capacity is 3a/16；After 2 minutes, detect that interior machine capacity is 4a/16, then Correspondingly, the running frequency of compressor should have A3 to be gradually loaded into A4.Wherein, A3, A4 etc. are determined by the performance of compressor itself Fixed numerical value, and the first preset duration can according to actual needs be set by user, wherein a be unit nominal refrigerating capacity/ Heating capacity, unit KW.

In one possible implementation, before step S103, control compressor are run according to running frequency, the party Method further includes：Determine the operational mode of unit, wherein operational mode is refrigeration mode or heating mode.It is understood that Regulative mode when air-conditioning is in heating mode and refrigeration mode simultaneously differs.

In one possible implementation, as shown in Fig. 2, being transported according to running frequency in step S103, control compressor After row, this method further includes：

Step S201, the temperature of outlet pipe is detected；

Step S202, according to operational mode and the temperature of outlet pipe, the operation of compressor is controlled.

Wherein, when unit is in refrigeration mode, step S202 includes：Whether the current operation frequency of monitoring compressor can Enough meet claimed below：The conduit temperature for ensureing end and the difference of default ambient temperature value are in the first pre-set interval；Such as Fruit is, then when the temperature of outlet pipe is reduced to the first default outlet pipe temperature, controls compressor shutdown；When the temperature of outlet pipe When being increased to the second default outlet pipe temperature, control compressor is according to operation start instruction input by user；Wherein, the water of end Tube temperature degree is the average value for the conduit temperature for each having turned on wind disk, and the second default outlet pipe temperature is higher than the first default outlet pipe Temperature, operational order is for determining operational mode, default ambient temperature value and the unlatching quantity of wind disk, gear.

When unit is in heating mode, step S202 includes：Whether the current operation frequency of monitoring compressor can expire Foot is claimed below：The conduit temperature for ensureing end and the difference of default ambient temperature value are in the second pre-set interval；If so, Then when the temperature-of outlet pipe presets maximum water temperature >=first preset difference value, control compressor shutdown enters standby shape State；When third presets temperature >=second preset difference value of outlet pipe temperature-outlet pipe, control compressor is inputted according to user Operation start instruction；

Wherein, it is the current desired temperature wanted set by user to preset ambient temperature value, that is to say, that unit need to be by this temperature It spends to generate heating capacity or refrigerating capacity.And first pre-set interval and the second pre-set interval it is different.Above-mentioned preset value can be according to water The performance of pipe and the actual needs of user are set.For example, the first pre-set interval can be 15 degrees Celsius to 17 degrees Celsius, the Two pre-set intervals can be 20 degrees Celsius to 30 degrees Celsius.

Since there are 2 heat exchange, (i.e. refrigerant carries out first time heat exchange to unit with water, and the water and needs for being delivered to end are dropped The space of temperature or heating carries out second and exchanges heat), it can lead to there is delay when control.That is, when compressor add unloading (into Line frequency is adjusted) when, since water has certain volume, to pass through 2 heat exchange and pipeline, there can be certain delay, Prevent the running frequency of compressor matches from the environment temperature with end.And on the other hand, in water chiller-heater unit, end The temperature of water pipe and the heating capacity or refrigerating capacity of unit release have certain correspondence, heating capacity and refrigerating capacity directly to determine again Whether the end environmental temperature of unit can reach default ambient temperature value.The then running frequency of fine-tuning compressor as a result, and While fine tuning, difference is determined in real time, so that difference is in 15 degrees Celsius to 17 degrees Celsius in cooling mode, is being heated 20 degrees Celsius to 30 degrees Celsius are under pattern.By finely tuning the running frequency of compressor according to difference in the embodiment of the present invention, So that difference meets the method for certain condition, in the case of further can solving delay, caused end environmental temperature is unsatisfactory for The problem of user demand so that the environment temperature of end is more nearly default ambient temperature value, and more stablizes.

For example, to prevent water temperature over-high in unit running process in pipeline or too low, ensure the safety of unit.When Unit is in refrigeration mode and when the temperature of outlet pipe is to 3 DEG C (first default tube temperature degree of publishing books), controls compressor shutdown, keeps away Exempt from water temperature and continue to be reduced to 0 DEG C water pipe is caused to freeze rupture.When the temperature of outlet pipe is increased to 7 DEG C of (second default water outlet tube temperatures Degree) more than when, compressor is according to operation start instruction input by user, at this point, the temperature of outlet pipe is in a safe condition.Work as machine When group is in heating mode, the temperature of outlet pipe need to be avoided excessively high, in order to avoid outlet pipe is damaged.Then when outlet pipe temperature is super The value for crossing 55 DEG C (third preset outlet pipe temperature) is 2 DEG C (first preset difference values), and when continuing 1 minute, and control compressor stops Machine, into standby mode.When the value that outlet pipe temperature is less than 45 DEG C (the 4th default outlet pipe temperature) is 5 DEG C, (second is default poor Value) more than when, control compressor according to operation start instruction input by user.Thus, it is ensured that pipeline in unit running process Interior water temperature over-high is too low and damaged to water pipe so that unit operation is safer.

It should be noted that on regulative mode shown in Fig. 2 regulative mode shown in Fig. 1 cooperation detection end water pipe Temperature is finely adjusted the running frequency of compressor, is to the further supplement of regulative mode shown in FIG. 1 and optimization, with into one Step is so that the ambient temperature value of end is more met the needs of users.

In one possible implementation, as shown in figure 3, determining compressor in step S102, according to interior machine capacity After running frequency, this method further includes：

Step S401, the ambient temperature value of end is determined；

Step S402, it is closed according to the operational mode of unit, the ambient temperature value of end and the size of default ambient temperature value System, is adjusted the running frequency of compressor.

In one possible implementation, as shown in figure 4, step S401, determining that the ambient temperature value of end includes：

Step S4011, it obtains the ambient temperature value for each wind disk having turned on and determines the wind disk quantity that end has turned on.

Step S4012, when quantity is more than preset quantity, according to sequence from low to high to the ambient temperature value of acquisition into Row sequence, and equal ambient temperature value sequence arranges；

Step S4013, the remaining environment for excluding the first minimum ambient temperature value and last position highest ambient temperature value is determined The average value of temperature value；

Step S4014, average value is determined as to the ambient temperature value of end.

Wherein, the wind disk having turned on is the current wind disk normally started, and not actuated wind disk and faulty wind disk are equal It forecloses.Assuming that there is 16 wind disks having turned on, the ambient temperature value of each wind disk is respectively T1, T2, T3 ..., T16.And Be ranked up from left to right according to the sequence of ambient temperature value from low to high, equal ambient temperature value sequence arrange after, still for T1,T2,T3……,T16.Then remove minimum and peak, excludes error and special circumstances to ensure so that acquires is averaged It is worth more acurrate.And average value is determined as to the ambient temperature value of end.This ambient temperature value can accurately represent the flat of end Equal ambient temperature value.

After the ambient temperature value of end is determined, when unit is in refrigeration mode, step S402 is according to unit The running frequency of compressor is adjusted in operational mode, the ambient temperature value of end and the magnitude relationship of default ambient temperature value Including：When the ambient temperature value of end is more than default ambient temperature value, the running frequency of compressor is improved；When the environment of end When temperature value is less than default ambient temperature value, the running frequency of compressor is reduced；When the ambient temperature value of end is equal to default ring When the temperature value of border, keep the running frequency of compressor constant.

When unit is in heating mode, step S402, according to the operational mode of unit, the ambient temperature value of end with it is pre- If the magnitude relationship of ambient temperature value to the running frequency of compressor be adjusted including：When the ambient temperature value of end is more than in advance If when ambient temperature value, reducing the running frequency of compressor；When the ambient temperature value of end is less than default ambient temperature value, carry The running frequency of high compressor；When the ambient temperature value of end is equal to default ambient temperature value, the operation frequency of compressor is kept Rate is constant.

Wherein, the running frequency of compressor is the running frequency determined according to method shown in FIG. 1, in this realization method, It is adjusted based on the running frequency.In refrigeration mode, if the ambient temperature value of end is more than default environment temperature Value, then be turned up running frequency, and end environmental temperature value is enable quickly to tend to default ambient temperature value；In heating mode, such as The ambient temperature value of fruit end is less than default ambient temperature value, then running frequency is turned up, keeps end environmental temperature value quick Tend to default ambient temperature value.As a result, by coarse adjustment compressor frequency, to adjust the ambient temperature value of end so that end Ambient temperature value is more met the needs of users.

In one possible implementation, as shown in figure 5, determining compressor in step S102, according to interior machine capacity After running frequency, method further includes：

Step S601, the ambient temperature value for the wind disk each having turned on is obtained respectively；

Step S602, according to the operational mode of unit, the ambient temperature value for the wind disk each having turned on and default environment temperature The magnitude relationship of angle value is respectively adjusted the valve corresponding to each wind disk having turned on.

Wherein, when unit is in refrigeration mode, step S602, according to the operational mode of unit, the wind each having turned on The magnitude relationship of the ambient temperature value of disk and default ambient temperature value, respectively to the valve corresponding to each wind disk having turned on into Row is adjusted：When meeting t₁-t₂≥t₃When, it controls the valve corresponding to wind disk and is opened with the first amplitude；When to continue second pre- If meeting 0≤t in duration₁-t₂< t₃When, it controls the valve corresponding to wind disk and is opened with the second amplitude；When to continue second default Satisfaction-t in duration₃< t₁-t₂When≤0, controls the valve corresponding to wind disk and opened with third amplitude；When to continue second default Meet t in duration₁-t₂≤-t₃When, it controls the valve corresponding to wind disk and closes, so that wind disk is shut down, and outage information is sent out It send to host, wherein outage information is used to indicate host and sends prompt message to user, to prompt user's wind disk to shut down；Work as institute There is the wind disk having turned on to meet t in lasting third preset duration₁-t₂≤-t₄When, control compressor shutdown；And when any one A wind disk meets t₁-t₂≥t₅When, control compressor is according to operation start instruction input by user；Wherein, t₁For any one Open ambient temperature value, the t of wind disk₂For default ambient temperature value, t₃For the first preset difference value, t₄For the second preset difference value, t₅For Third preset difference value, the first amplitude are more than the second amplitude and are more than third amplitude.
