Description
Technical field
The present invention relates to frozen products insulated container technical field, more particularly to a kind of frozen products insulated container cold, there is the refrigeration collection
The frozen products insulated container of vanning cold and the control method of the frozen products insulated container cold.
Background technology
With the development of Refrigeration Transport Market and technology, user is more next to the uniformity requirement of frozen products insulated container the temperature inside the box
Higher, but the structure of refrigerated container body limits the front end for making its cold (or claiming refrigerator) can be only installed at casing (no
One end of chamber door is set)；The operation of cold and the control of state, are all wind pushing temperature sensor, the return air temperature using cold
The wind pushing temperature of degree sensor collection judges the temperature conditions in case with return air temperature signal, is made by controlling the load of cold
The difference that wind pushing temperature or return air temperature are obtained with design temperature is maintained at a zone of reasonableness.
Control of Chiller the temperature inside the box scope is -30 DEG C～30 DEG C at present, generally with -10 DEG C as freezing and refrigeration line of demarcation, -
It is refrigeration for more than 10 DEG C, judges that using design temperature running status belongs to freezing or refrigerates.
Under frozen state, the sign temperature of the temperature inside the box is wind pushing temperature (representing the temperature inside the box with wind pushing temperature), writes from memory
Recognize evaporating fan and run high wind all the time.After wind pushing temperature is close to design temperature, turns low wind operating, realize energy-conservation.
Under freezing state, the sign temperature of the temperature inside the box is return air temperature (representing the temperature inside the box with return air temperature), writes from memory
Recognize evaporating fan and run low wind all the time.Can be poor with design temperature higher, when needing to goods fast cooling, evaporating fan employing
Run up.
For the control of cold, including for the power of cold is increased or is reduced, also including the steaming for adjusting cold
Send out the rotating speed of the evaporating fan of device.
The cold of prior art, typically two grades of the rotating speed of the evaporating fan, i.e., high wind shelves and general wind shelves.In return air temperature
When degree or wind pushing temperature are close to design temperature, illustrate that the temperature conditionss in refrigerating box have reached the requirement of setting, you can control
Cold is run using low-power and low wind speed.And when differing larger in return air temperature or wind pushing temperature with design temperature, explanation
The requirement that temperature conditionss in frozen products insulated container also not up to set, need to control cold and be run using high power and high wind speed.
However, the cold of prior art is controlled, the correlation behavior parameter for not introducing distal end is controlled.Easily cause case
Interior temperature skewness；For example under certain conditions, the front end that the temperature at distant with cold door end is located with cold
Temperature can have a certain distance, it is assumed that the temperature inside the box sets and should be -10.5 degrees Celsius, and now door end temperature is -5 Celsius
Degree, and head temperature has been reduced to -11 degrees Celsius, now cold is made by detection return air temperature and the difference of design temperature
Be the control mode that is run using low-power and low wind speed, and the control mode now can not reflect the demand at an end,
So that the temperature at door end is more unable to reach sets requirement, easily it is lost goods.
In addition to the door end farthest with cold, other in container have the position of different distance with cold, also difficult
Synchronously to reach the temperature of setting with frozen products insulated container front end, therefore it is also required to new control mode to realize in frozen products insulated container
The temperature of each position is uniform.
If cold is blown using high wind speed all the time, the uniformity of the temperature inside the box can be effectively improved, but increases cold
Power consumption, it is impossible to which the purpose for reaching energy-conservation can not obtain good economic benefit.
In addition to temperature homogeneity, other conditions parameter such as humidity, composition of air etc. in frozen products insulated container also have
The demand of uniformity, it is also desirable to the uniform of each position in container is reached by adjustment that cold is run, in prior art
Equally do not possess the condition of the adjustment.
