Abstract
The invention relates to a container cold storage unit composed of a standard container and a cold storage unit body. The cold storage unit body is mainly composed of a frequency-variable compressor, an air-cooling condenser, a plate type heat exchanger, an evaporator, a circulation fan, a pressure sensor and the like.
Description
Technical field
Container refrigeration is a kind of device integrating refrigeration and transport, and can make food security, efficiently, fresh-keeping is transported to all over the world.
Background technology
Container refrigeration unit in the market, monopolize by external brand, for break external industry monopolization and to the blockade for military's product, special independent research container refrigeration unit.
1) what conventional container refrigeration unit used is Conventional press or digital scroll compressor, Conventional press unit makes the utilization interval of unit be restricted, digital vortex unit is shorter for service life, the frequent opening and closing of scroll plate can affect the service life of compressor greatly, reliability, stability is not high.
2) system unit is complicated, and appearance and size is large, operates heavy.
3) high pressure-temperature parts are many, complex structure, there is many safety factors.
4) the material of the military to product, the particular/special requirement of six property aspects is not considered fully.
patent of invention content
For overcoming overseas enterprise, the product of Chinese military being blocked, for the blank of domestic market, improving the quality of life of ocean personnel, the invention provides a kind of reliability stability high, the container refrigeration unit carrying out temperature control that can be quick, flexible, comfortable.Mainly comprise frequency-changeable compressor, air-cooled condenser, evaporimeter, plate type heat exchanger, circulating fan, control valve member and microcomputer controller etc.Main technical requirements is for container provides low-temperature receiver, guarantees food, and vegetables avoid the impact by external environment to go bad in long distance transportation process, keep certain freshness.
the technical scheme of patent of the present invention:
The operation principle of container refrigeration unit and being analyzed as follows:
1. unit is under the running environment of freezing and heat, can controlled cooling model load accurately, the Signal transmissions that sensor gathers is to micro computer, microcomputer controller passing ratio calculus and Numerical control valve control the frequency of compressor accurately, it is the frequency adaptation working condition requirement of compressor, export suitable refrigerating capacity, reach the effect of accurate temperature controlling.
2. unit is under completely freezing and unloaded mode of operation, can control the temperature of reefer cargo accurately.Controller carrys out the operation conditions of conditioning equipment by the temperature of return air sensor and set temperature.
3. the utilization of supply air sensor, prevents frosting from causing damage.If supply air sensor is damaged, with return air temperature, unit can add that a side-play amount carries out the control of temperature.
4. for point integral algorithm controls condenser temperature, microcomputer controller passing ratio guarantees that expansion valve hydraulic pressure is constant.Air-cooled condenser carries out self-control by the start and stop of cooling fan, cools operating mode under normal circumstances, and temperature is 30 DEG C; Lower 20 DEG C of freezing situation.
5. be on the whole, sensor in unit and probe by the information data transmission that collects to microcomputer controller, microcomputer controller is by calculating, shaping modes, frequency-changeable compressor carries out by the change of frequency the adjustment exporting refrigerating capacity, the cold-producing medium of HTHP enters air-cooled condenser, constant in order to ensure expansion valve hydraulic pressure, and cooling fan carries out start and stop adjustment.High pressure freon liquid through expansion valve reducing pressure by regulating flow, then becomes superheated liquid, enters evaporimeter, so circulates.
By the sensor Resurvey signal in container, be transferred to micro computer, microcomputer controller carries out calculating and the adjustment of next round.
patent of the present invention has following beneficial effect:
1, economize energy, frequency-changeable compressor low energy consumption.
2, environmental protection.Use R404A environment friendly refrigerating fluid.
2, structure is simple, easy to operate, uses microcomputerized control automaticity high, and setting duty point, effectively provides the operating efficiency of operating personnel;
3, reliability, maintainability is high.Take into full account the impact of environment, select corrosion-resistant, shock resistance, material that quality is light.The components and parts maintenanceability selected is high, practical, durable.
4, the military is met to product quality aspect, the particular/special requirement of secret aspect etc.
Accompanying drawing explanation
Accompanying drawing 1 is the structure diagram of patent of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, patent of the present invention is described further:
Container refrigeration unit is made up of with refrigeration unit the container of standard, refrigerates unit primarily of frequency-changeable compressor, air-cooled condenser, plate type heat exchanger, evaporimeter, circulating fan, the compositions such as pressure sensor.
Container refrigeration unit is mainly used in the long distance transportation of food vegetables and fruits, main operational principle: the principle using air conditioner refrigerating, for providing low-temperature receiver in container.
The utilization of frequency-changeable compressor on container refrigeration, make container more flexible to the adjustment of operating mode, working environment is widened further.
The utilization of microcomputer control panel, the automaticity of unit is higher, operation, maintenance, report to the police more simple.
Body takes into full account the harsh environments of unit, uses corrosion-resistant, and quality is light, the aluminium alloy of strong shock resistance.
