What is the difference between cold storage and air-conditioned storage
What is the difference between cold storage and air-conditioned storage?
Nowadays, there are many storage polyurethane boards. Although many people now use cold storage, some air-conditioned storage are also widely used. Compared with cold storage, air-conditioned storage has the following advantages:
1. Modified atmosphere storage belongs to the category of high-temperature storage. The fresh-preserved food will not freeze, the original food and flavor will be retained, and the nutrition will not be lost
. In the same fresh quality and temperature conditions, controlled atmosphere cold storage preservation time is 3 to 5 times of cold storage, for some even up to several times the food is cold unmatched;
3. 3. The air-conditioning operating temperature is 0 ~ 8 ℃, which is 18 ~ 33 ℃ higher than that of ordinary low-temperature cold storage. Therefore, the power consumption of air-conditioning is much smaller than that of ordinary cold storage during the same fresh-keeping time;
4. The air-conditioned warehouse uses inert gas to isolate the air, which can effectively inhibit the respiration of food cells and then mature, which not only prolongs the preservation time, but also extends the shelf life of the food after storage, making it possible for the food to be sold for a longer time after storage. ;
5. Air conditioned participation by CO2 gas atmosphere, and can not only inhibit the formation of ripening effect C2H4 like components, and has a bactericidal, antibacterial, effect eliminating side effects of pesticides;
6. Because the air conditioning adopts a humidification system, not only the water of the food itself will not be lost, but also the color and texture of the food will not be changed, which reduces the storage loss of the food and retains the original quality of the food.
7. The air-conditioning storehouse adopts PLC program for automatic control, strong safety and reliability, and high production efficiency.
Is there any occupational disease at work in the cold storage
Is there any occupational disease at work in the cold storage?
Due to the perennial low temperature of the cold storage, workers in this profession often suffer from freezing, cold feet, backache, back pain, and even suffer from arthritis.
Some of the novices who are engaged in cold storage work are not used to it, and few people can eat this bitterness.
Especially the porters working in large-scale cold storage, it is better if they work in winter, because after all, the temperature difference between the inside and the outside of the store is not very large, and the body will not be strongly infected by temperature. Later, like fire, you can't afford to be strong even after working for a long time.
Cold storage is actually a kind of low-temperature combined air-conditioning equipment. Cold storage (refrigerator) is also a type of refrigeration equipment. Compared with refrigerators, the refrigeration area is much larger, but they have the same cooling principle.
Extended information
Cold storage function:
1. The refrigeration system of a cold storage mainly includes a cold storage unit, which is the core of the cold storage and ensures the supply of cold sources in the cold storage room. The control device is the brain of the cold storage, and it directs the refrigeration system to ensure the cold supply.
2. The cold storage warehouse is a place for storing fresh agricultural products. Its role is to maintain the stability of the low temperature environment. Generally speaking, the thermal insulation performance is called thermal insulation.
3. The good thermal insulation structure of the cold storage room can maximally keep the amount of cold produced by the cold storage unit from leaking out in the cold storage. On the other hand, it is to minimize the leakage of heat outside the cold storage into the cold storage. The main differences.
Cold storage use:
1. Cold storage is mainly used for the constant temperature storage of food, dairy products, meat, aquatic products, poultry, fruits and vegetables, cold drinks, flowers, green plants, tea, pharmaceuticals, chemical materials, electronic instruments, etc.
2. The cold storage keeps a certain low temperature in the room through artificial refrigeration. The wall, floor and flat roof of the cold storage building are covered with a certain thickness of heat insulation material to reduce the heat transfer outside the cold storage.
3. In order to reduce the absorption of solar radiation energy, the surface of the cold storage exterior wall is usually painted white or light color. Therefore, the cold storage building is different from the general industrial and civil buildings, and has its own unique structure.

Find Out How to Make your Home Energy Efficient
Find Out How to Make your Home Energy Efficient
High energy prices have been on the rise in the United States. There are ways that you can make your home hot weather ready while keeping cool in the summer.
The first thing you may want to do is get an energy audit to see how energy efficient your home really is. An energy auditor will come to the home and check all major appliances, heating and cooling systems, as well as windows, doors and insulation. The entire structure of the home will be assessed and get an overall rating. This rating will also come with a report that will give suggestions on how you can change the home, or make improvements to it so it is more energy efficient.
There are some things you can check in your home to identify areas that are in need of improvement. Check your garage walls, basement, attic and attic stairway to see if there are any major drafts or areas where the insulation is old or in need of replacement.
Check your central air conditioning system every spring and have it serviced. This will make sure that it is working properly and efficiently so that money is not wasted on leaks. You may also want to clean or replace the filter once every two months and always seal any leaks or holes around pipes, whether they be plumbing or heating.
Hire a contractor to seal any leaky ducts so that airflow is distributed equally and the equipment is operating at peak efficiency.
Are your windows single or double pane? If they are single pane, you may want to consider installing double pane windows with high performance glass. This ensures that there are fewer drafts in the house.
Consider a programmable thermostat that can regulate the home's temperature even when you are not home. That way, the air conditioning will not cool the home when you are not home, or in the evenings when the air conditioning may not be as necessary.
When you install window coverings, curtains, drapes or blinds, it helps seal off the windows and doors from both any drafts and the sun. It can help keep your house cool in the day by protecting the home from the sun's hot rays.
Consider ceiling fans as an alternate source of cooling. These ceiling fans do not use as much energy as air conditioning and keep a bedroom very cool.
If you have room around the property of the house, consider planting a tree. A tree can act as a natural cooling system for a house or bedroom window so that the sun is not in direct contact with the home. When the sun is not shining directly on the home, it can greatly decrease the heat that enters in the house.
If you can not plant a tree to shield the house, you may want to invest in applying a reflective coating to the roof. This reflective coating will redirect the sun's rays, bouncing the heat off of the home. A dark roof absorbs a lot of heat, so if you have one, consider getting a light roof that will also reflect the sun's rays.
There are many options for energy-saving appliances. Some of them can be great investments, but always check the energy claims to see if it really is saving you energy and if it is something that you could use in your home.
If you feel that energy conservation in your home is something that you can achieve, but need help with the investment to make all the improvements in your home, you may want to check out an Energy-Efficient Mortgage (EEM). You can get a loan towards the improvements of your house if the overall savings in the utilities are greater than the cost of the home improvements. Ask your energy auditor to help you determine the break even point where your costs match your savings, and savings will begin to take place. In the long term, great savings can be reaped by performing these home improvements.
Energy-Efficient Mortgages are a lot like normal mortgages, except you use the money for home improvements. Interest rates are usually low and payments and terms are negotiable. There are many lenders who offer this mortgage, so ask around or go to your local bank to see if there is someone who can help you. There are more papers to fill out and you must get an energy audit before applying for an EEM. The energy auditor Refrigeration Unit company can assist you and the lender in getting everything ready for the application process of the EEM. It takes the work off of both you and the lender.
By making home improvements you can save a lot of money on your utility bills and at the same time conserve energy. It's a win-win situation for both your pocket book and environment.
Today's automotive engines develop high temperatures
Auto Cooling System Service
Today's automotive engines develop high temperatures for any automobile that you might drive's cooling system. Simply put the role of the auto cooling walk in freezer system is to get rid of waste heat round as a supplementary task provide interior cabin heating and defrosting come the cold winter blowing down from Canada. Cooling and radiator systems of cars and vehicles are essential and vital. Thus it behooves you as a driver and motorist to carefully inspect your rad and basic auto cooling system components each and every time you open the hood up of your automobile.
What do experienced and to put it simply novice or would be mechanics scan and look for underneath their hoods or bonnets? Look for leaks around all hose connections, the water pump pulley, the radiator and thermostat housing. Next and in addition, look auto coolant hoses dry rot, cracks on the surface and excessive swelling or hardening of the hoses.
As well and also inspect the condition of the rad fan belt - its usually one long serpentine belt - that is unless you car is exceptional and has an all electric waster pump. Accumulation of bugs in the summertime ( as well as those left from summer drives and left as residue in the fall time), leaves and road film should be carefully and thoroughly cleaned from the radiator fins , using a brush , household detergent and a garden hose. On cars with air conditioning, the finned condenser sits in front of the radiator, and its surface is the one that gets blocked. Cleaning is important because anything blocking the flow of air through the condenser and radiator can well cause serious overheating - engine damage or just simply motorist inconvenience.
Proper coolant in the radiator twill allow the engine to work as warm as it should without boiling over in the summer and will give you antifreeze protection in cold Alberta Canada winter months.
The question often arises of what to do and what can be done concerning radiator heater hoses and heater hose repair and repairs. True a damaged heater hose can put your vehicle - be it car, truck or S.U.V, out of order and commission. This can be especially troublesome when you are on the road and away from any dealer facility - be it a local garage or auto dealer service center.
Some mechanics and service writer technicians advise that an easy method of temporarily correcting the problem and allowing you to safely drive the car to be repaired is to bypass the interior car heater completely.
In such situations work to remove the damaged heater hose from both the heater core at the cowl, and the water pump or engine, depending on which hose has been broken. Then remove the undamaged hose from the heater core at the cowl and reroute the hose back into the engine or water pump.
You now have one hose running from the engine to the water pump. You will not have an interior heater or working functional defroster if it is wintertime - yet in a pinch you should be able to drive to a repair shop be it local garage or auto dealership service center facility.
