The leaving water temperature T5 of the indoor environment temperature T4 and currently detected case tube heat exchanger that arrive are based on presetting mapping relations
Determine current fin normative surface temperature T2.
It further, further include controlling institute when the runing time of the motor reversal reaches preset dedusting operation duration
It states motor to restore to rotate forward or stop working, and resets the accumulated running time of the module water dispenser.
Further, the preset unit operation duration is 10 hours.
Further, the preset temperature numerical value T3 is 5 DEG C.
It further, further include the accumulative operation of module water dispenser described in start recording after electric-opening in the module water dispenser
Time.
Further, the step of judgement module water dispenser is in heating mode or refrigeration mode includes: to pass through exchange
To the detection of the working condition of valve to judge that the module water dispenser is in heating mode or refrigeration mode.
It further, further include the work shape for judging motor after the accumulated running time that step resets the module water dispenser
State, if motor is rotating forward state, again accumulated running time of logging modle water dispenser.
Further, the preset dedusting operation duration is 600s.
A kind of module water dispenser, comprising: fin temperature sensor, to be used on the fin of finned heat exchanger medium position
Detect the Current surface temperature T1 of fin；Environment temperature sensor, for detecting indoor environment temperature in indoor environment
T4；Leaving water temperature sensors, the water outlet set on case tube heat exchanger is with the leaving water temperature T5 for detecting case tube heat exchanger.
Compared with the prior art, the beneficial effect of the present invention is that passing through the accumulated running time of module water dispenser and the surface of fin
Temperature so that dust removal operation is more accurate and in time, effectively solves fin and changes as whether reaching the judgement of dedusting unlocking condition
The problem of heating caused by hot device dust accumulation incrustation and refrigeration effect reduce and module water dispenser power energy consumption rises.
Detailed description of the invention
Fig. 1 is flow chart of the invention.
Specific embodiment
The present invention is further explained in the light of specific embodiments:
Referring to shown in attached drawing 1, the present embodiment is a kind of module water dispenser finned heat exchanger dust removal method, wherein module water dispenser includes:

Environment temperature sensor in indoor environment, set on case tube heat exchanger water outlet leaving water temperature sensors and wind
Machine, the motor of the blower can realize that positive and negative rotation works；Secondly, the refrigeration of module water dispenser and the loop structure of heating are conventional show
There is technology, can refer to the Chinese patent that notification number is CN108168137A, details are not described herein.
In the present embodiment, module water dispenser finned heat exchanger dust removal method the following steps are included:
After electric-opening in module water dispenser, the accumulated running time of master control borad start recording module water dispenser, and judgment module water dispenser
In heating mode or refrigeration mode, the detection specifically by the working condition (commutation information) to reversal valve is described to judge
Module water dispenser is in heating mode or refrigeration mode.
When under determination module water dispenser is in refrigeration mode, master control borad passes through fin temperature sensor real-time detection fin
Current surface temperature T1, by environment temperature sensor real-time detection indoor environment temperature T4 and pass through leaving water temperature sensors
The leaving water temperature T5 of real-time detection case tube heat exchanger；Master control borad is according to currently detected indoor environment temperature T4 and current institute
The leaving water temperature T5 of the case tube heat exchanger detected is based on the presetting mapping relations (mapping relations i.e. fin standard surface temperature
The function corresponding relationship for spending T2 and indoor environment temperature T4 and leaving water temperature T5 is set by technical staff by test in advance
It is fixed) determine current fin normative surface temperature T2, by the Current surface temperature T1 of fin and currently determined fin standard
Surface temperature T2 compares (by the Current surface temperature T1 of fin and currently determined fin normative surface temperature when substantial
It is poor that T2 makees), if the Current surface temperature T1 of fin is higher than currently determined fin normative surface temperature T2 preset temperature numerical value
T3(temperature value T3 is 5 DEG C) and detect that the accumulated running time of module water dispenser reaches preset unit operation duration (unit
Operation duration is 10 hours), then determine to reach dedusting mode unlocking condition at this time, controls motor by rotating forward work and switch to reversion
Work reaches the clean function and effect of dedusting reversely to blow out the dust for blocking up product on fin heat exchanger；
When determination module water dispenser is under heating mode, if master control borad detects that the accumulated running time of module water dispenser reaches pre-
If unit operation duration (10 hours), then determine to reach dedusting mode unlocking condition at this time, then control motor by rotating forward work
Reversion work is switched to reversely to blow out the dust for blocking up product on fin heat exchanger, reaches the clean function and effect of dedusting；
Under dedusting mode, the runing time of motor reversal reaches preset dedusting operation duration and (in the present embodiment, removes
Dirt operation duration is 600s) when, control motor restores to rotate forward and (continue to heat or freeze) or stop working, and dump block
The accumulated running time of water dispenser, if motor is rotating forward state, again accumulated running time of logging modle water dispenser；
Continuous circulation through the above steps realizes the automatic dust removing of module water dispenser finned heat exchanger.
