Problems solved by technology

It may cause the heating tube to overheat, the current is overloaded, the circuit breaker takes off or the fuse is burnt due to overcurrent to play a protective role. If the circuit breaker or fuse is defective, if the current is too large and does not operate, there is a possibility of continuing to "dry burn" and cause a fire , and dry burning or partial dry burning will accelerate the aging of the protective layer plastic of the heating belt and affect the service life of the heating belt
Once the circuit breaker takes off due to overload, the drain pipe will be blocked during the next defrosting of the cold storage, and the drainage of the cold storage will not be smooth, and it will overflow to the ground of the cold storage

Embodiment 1

[0040] figure 1 It is a flow chart of the method for controlling the heating of the drainage pipe of the refrigerated air cooler for ships involved in the present invention.

[0041] Such as figure 1 As shown, this embodiment 1 provides a heating control method for the drain pipe of a refrigerated air cooler for ships, including: preheating the heating belt before the air cooler is defrosted; the heating belt is kept in a heated state when the air cooler is defrosting; and After the defrosting of the air cooler is completed, the heating of the heating belt is delayed, which realizes the control of the heating time of the heating belt, achieves energy saving in electricity consumption, prolongs the service life of the heating belt, reduces maintenance costs, and avoids the "dry burning" of the heating belt "The possibility of overheating, to avoid safety hazards as much as possible.

[0042] Based on the design and commissioning experience of marine refrigerating devices, and...

Embodiment 2

[0061] figure 2 It is the principle block diagram of the heating control system of the drainage pipe of the refrigerating air cooler for ships involved in the present invention.

[0062] Such as figure 2 As shown, on the basis of embodiment 1, this embodiment 2 also provides a kind of refrigerating air cooler drainage pipe heating control system for ships, including: a control module, and a heating belt connected to the control module; the control module can But not limited to the use of PLC modules, the control module can directly adopt cold storage PLC; a time relay is arranged between the control module and the heating belt; the control module is suitable for controlling the heating of the heating belt through the time relay Time to keep the drain pipe unblocked during the defrosting process of the air cooler (preheating before defrosting, simultaneous heating during defrosting, and delayed heating after defrosting).

[0063] In this embodiment, the control module is su...

Abstract

The invention belongs to the technical field of refrigerating devices, and particularly relates to a heating control method and system for a drain pipe of a refrigerating air cooler for ships. The heating control method for the drain pipe of the refrigerating air cooler for the ships comprises the following steps that a heating belt before defrosting of the air cooler is preheated; when the air cooler defrosts, the heating belt is kept in a heating state; and the heating belt delays heating after defrosting of the air cooler is finished, so that the heating time of the heating belt is controlled, the effects of saving electricity and energy, prolonging the service life of the heating belt and reducing the maintenance cost are achieved, the possibility of overheating of dry burning of the heating belt is avoided, and potential safety hazards are avoided as much as possible.

Description

technical field [0001] The invention belongs to the technical field of refrigerating devices, and in particular relates to a heating control method and control system for a drainpipe of a refrigerating air cooler for a ship. Background technique [0002] The power range of common ships’ refrigerating devices is mostly 2.4-10kW, and the drain pipe of the air cooler has a heating band, and the power of the heating band has always occupied a certain proportion of the power of the compressor. Moreover, the poorly controlled heating band is unsafe for ship cold storage. One of the factors, the heating belt is also one of the vulnerable parts. How to find a new technology that saves energy, is safe, and reduces the amount of maintenance is a technical requirement. [0003] Ships often have 2-5 storerooms. The more storerooms, the more power this part of the heating belt will consume, accounting for about 5-7% of the power consumption of the compressor. Taking a certain type of do...
