The row t1 time (such as: it after t1=15min), re-executes above-mentioned steps b~d and is judged, move in circles progress.In the application
In embodiment, the method for operation that the air-conditioning system does not start enthalpy-increasing function can be understood as commonly running, and only enables first and follows
Loop back path executes ordinary cycle.
Fig. 3 is a kind of flow diagram of the increasing enthalpy control method of air-conditioning system provided in an embodiment of the present invention, this method
Executing subject can be the control unit (for example, the control units such as single-chip microcontroller, MCU) in air-conditioning system.As shown in figure 3, extremely
When few satisfaction presets increasing enthalpy entry condition as follows, air-conditioning system can just be activated enthalpy-increasing function:

S12: current increasing enthalpy degree of superheat Ts '≤target increasing enthalpy degree of superheat Ts；
S13: air-conditioning system high side pressure Ph≤goal pressure P；
Otherwise, do not start enthalpy-increasing function.
In practical applications, before executing step S11, it is necessary first to be switched on and (open air-conditioning system), such as by distant
It controls device and opens air-conditioning system, make it into normal operating conditions.Above-mentioned steps can be applied to low-temperature heating increasing enthalpy process.Together
Reason, to start enthalpy-increasing function, needs current environmental temperature T >=critical environmental temperature T during high-temperature refrigeration increasing enthalpyE；When
Preceding increasing enthalpy degree of superheat Ts '≤target increasing enthalpy degree of superheat Ts；Air-conditioning system high side pressure Ph≤goal pressure P.Actual temp value
And pressure value, it can be set according to the actual situation.
Based on same thinking, the embodiment of the present invention also provides the increasing enthalpy control method of another air-conditioning system, the control
As shown in flow chart 4, specific steps may include: method processed
S21: judge whether current environment parameter meets preset condition；

It is illustrated.For example, after power-up, acquiring current environmental temperature T by environment temperature sensor.It further, will be current
Environment temperature T and preset critical environmental temperature TEIt is compared, if after comparison, it was found that current environmental temperature T is greater than critical environment
Temperature TE, then starting increasing enthalpy is not needed；If after comparison, it was found that current environmental temperature T is less than or equal to critical environmental temperature TE, then into one
Step ground obtains current increasing enthalpy degree of superheat Ts '.
Further, (target increases by the current increasing enthalpy degree of superheat Ts ' that will acquire and preset target increasing enthalpy degree of superheat Ts
The enthalpy degree of superheat can be set according to experiment or practical situations) it is compared, if current increasing enthalpy degree of superheat Ts ' is less than mesh
Increasing enthalpy degree of superheat Ts is marked, then does not temporarily start increasing enthalpy, so as to prevent compressor sucking large amount of liquid refrigerant from leading to compressor
Liquid hammer.
Further, if current increasing enthalpy degree of superheat Ts ' is less than target increasing enthalpy degree of superheat Ts, further more current air-conditioning
The size of the pressure Ph and goal pressure P of system high pressure side.If air-conditioning system high side pressure Ph is greater than goal pressure P, open
Dynamic enthalpy-increasing function；If air-conditioning system high side pressure Ph is less than or equal to goal pressure P, does not start enthalpy-increasing function, prevent from triggering
Compressor high pressure stoppage protection condition causes compressor superpressure to be shut down.Through the above scheme, stable low-temperature enthalpy-increasing may be implemented
Control, will not impact busbar voltage, avoid the occurrence of shutdown caused by compressor liquid hammer or compressor high voltage protective etc. and ask
Topic.
In one or more embodiment of the invention, the parameter detecting in above-mentioned S21 judgment step need to be set first
Continuous detection in timing is long.In practical applications, due to the influence of environment temperature, influence of temperature sensor sensitivity etc., meeting
The current increasing enthalpy degree of superheat got is caused small range fluctuation occur.In order to ensure acquisition the current increasing enthalpy degree of superheat it is reliable
Property, guarantee the stabilization of increasing enthalpy control system, after the increasing enthalpy degree of superheat that lasting a period of time (the first setting duration) can be monitored,
Judge whether the current increasing enthalpy degree of superheat is higher or lower than the target increasing enthalpy degree of superheat.For example, sample frequency is 60HZ, it is continuous to detect
One minute current increasing enthalpy degree of superheat, then will the current increasing enthalpy degree of superheat collected each time and the progress of the target increasing enthalpy degree of superheat
Compare, if being all higher than the target increasing enthalpy degree of superheat, closes increasing enthalpy control switch；If occurring not higher than the target increasing enthalpy degree of superheat
The current increasing enthalpy degree of superheat, then maintaining increasing enthalpy control switch is original state.It is of course also possible to the current increasing to being consecutively detected
Average value is compared by enthalpy degree of superheat averaged with the target increasing enthalpy degree of superheat.It should be noted that increasing mentioned here
Enthalpy control switch is remained stationary state, it can be understood as, if increasing enthalpy control switch was originally in the open state, still it is maintained out
State is opened, was in close state originally if increasing enthalpy control is kept an eye on, appoints and so maintains to be in off state.Technical side through this embodiment
Case, it can be ensured that the current increasing enthalpy degree of superheat of acquisition it is reliable.
In one or more embodiment of the invention, the parameter detecting in above-mentioned S22 judgment step need to be set second
Continuous detection in timing is long；Parameter detecting in S23 judgment step need to be set in duration in third continuously to be detected.It needs to illustrate
It is that it is to be directed in different estimate of situation to be made that the first setting duration, the second setting duration and third mentioned here, which set duration,
The difference of duration indicates that the first setting duration and the second setting duration can indicate identical duration, can also indicate different
Duration can be specifically determined according to practical situations.The unlatching of increasing enthalpy control switch in the present embodiment judges item
Part is similar to the closing Rule of judgment of increasing enthalpy control switch in above-described embodiment, is not repeated to describe in the present embodiment.Pass through
The present embodiment technical solution, it can be ensured that the current increasing enthalpy degree of superheat of acquisition it is reliable
In one or more embodiment of the invention, about 15min continuation is run after starting air-conditioning system enthalpy-increasing function
The judgement of S21~S24 step.In practical applications, it is usually the air-conditioning system under low temperature or the condition of high temperature that user, which opens air-conditioning,
Middle all parts and sensor can just further determine whether to open enthalpy-increasing function after requiring normal table operation.It avoids rashly
Opening increasing enthalpy causes system to be unable to steady operation.
In one or more embodiment of the invention, enthalpy-increasing function is activated in air-conditioning system or is not activated increasing enthalpy fortune
Continue the judgement of S21~S24 step after one preset duration of row.
In one or more embodiment of the invention, system high side pressure is compressor air-discharging lateral pressure；Its target
