The cooling water of the cooler, what kind of water is the cooling water

Taizhou Hengda heat exchange equipment manufacturing (formerly Jiangyan Hengda Hydraulic Machinery Manufacturing) specializes in the manufacture of electric heating elements, electric heaters, water system supplementary heaters, air duct (tube) heaters, heat exchangers, marine and land shell and tube dry evaporators, condensers, oil coolers, liquid reservoirs, gas tanks, oil separators, flooded evaporators and pressure vessels.

Cooling water is a kind of wanton name for the functional type, not to say what kind of water it is, but to say that its function is to cool the chilled water.

Cooling water, also known as coolant, should be called antifreeze coolant, which means coolant with antifreeze function. Cooling water prevents the coolant from freezing and cracking the radiator and freezing the engine cylinder when the coolant is stopped in the cold winter, and the body or lid from rotting.

But antifreeze isn't just for winter, it's supposed to be used all year round. In the normal maintenance program of the car, the engine cooling water needs to be replaced every year of driving.

The role of cooling water is:

1. Prevent the coolant from freezing and cracking the first leakage radiator and freezing the engine cylinder block when the coolant is stopped in the cold season.

2. Prevent corrosion of metal parts and aging of rubber parts.

3. Reduce the generation of scale, so as not to block the circulation pipeline and affect the heat dissipation function of the cooling system.

4. Prevent the water temperature of the engine from being too high and ensure that the engine can run at normal working temperature.

5. Provide lubrication for water pump thermostat and other components. <>

Antifreeze can prevent the coolant from freezing the radiator and freezing the engine block when it is parked during the cold season, but water does not have this function. Antifreeze is used not only in winter, but also all year round. During the normal maintenance of a car, the engine antifreeze needs to be replaced every year.

In addition to antifreeze, automotive antifreeze coolant also has the following functions:

1.Anti-corrosion function. The engine and its cooling system are made of metals, including copper, iron, aluminum, steel, and solder.

These metals are exposed to water at high temperatures, which can corrode and rust over time. Antifreeze coolant not only does not corrode the engine cooling system, but also has the function of anti-corrosion and rust removal.

2.Antifreeze coolant has a high boiling point. The boiling point of water is 100, and the boiling point of high-quality antifreeze coolant is usually 110 above zero, so it is more difficult to boil antifreeze coolant in summer than water.

3.Antifreeze coolant prevents fouling. When using water as a coolant, the biggest headache for drivers is limescale.

The metal surface of the water tank and water jacket is attached to the scale, and the heat dissipation effect is getting worse and worse, and it is difficult to remove it. The high-quality coolant is made from distilled water and has added anti-scale additives, which not only does not produce limescale, but also has a descaling function.

The central air-conditioning host is composed of four parts: compressor, transpirator, condenser and throttle valve, the compressor supplies energy, the condenser lowers the temperature of the refrigerant coming out of the compressor, and the medium is water, which is the cooling water, which is connected to the cooling tower. The transpirator is a refrigerant transpiration and endothermy, and the water flowing through the transpirator is chilled water, and the temperature of the chilled water drops after the heat is absorbed, and the cool air is blown into the room through the air conditioning unit to cool down. Compared with household air conditioners, the buried indoor unit is the transpirator, and the outdoor unit is the condenser, but the household is blown out for refrigeration, and the central air conditioner is the water flowing through the transpirator and then exchanging heat indoors.

Chilled Water - Cooling Water - Condensate Water The cooling water lowers the temperature of the refrigerant, and the water flowing through the condenser is the cooling water, and the water flowing through the transpiration tracker is the chilled water. The condenser is to reduce the temperature of the refrigerant coming out of the compressor, the medium is water, water is not good to be a refrigerant, the refrigerant mainly includes ammonia, carbon dioxide, sulfur dioxide, chloromethyl, Freon, etc., water is used as a refrigerant. Chilled water:

The cooling capacity of the air conditioner is sent into the room through the pipe and water pump, and then the fan coil unit of the room communicates to the space. Chilled water is a means of transport that transports cooling capacity from the air-conditioning room to the room in which it is used. Cooling water:

It is the air conditioner that generates a lot of heat through the ducts during the refrigeration process. The water pump is sent to the outdoor cooling tower for cooling, that is, the cooling water is the means of transportation that sends the heat generated by the main engine out of the outside. Condensate:

It is the cold condensation water that occurs from the air during the exchange of cold and heat in the room fan coil unit, and has nothing to do with the water of the system. Chilled water, cooling water, and condensate can be put together to understand that the main engine and the end of the water system are exchanged for heat through chilled water, and the main engine and the cooling tower are used to exchange heat through the cooling water, and the end air treatment equipment will condense water after obtaining the cold and heat of the chilled water and the indoor air. Chilled water Cooling water for transpirators, cooling water Cooling water for cooling condensers, condensate water Water condensed when the temperature drops.

Cooling water: It is generally refrigerated by the cooling water tower, and the water at room temperature of 35 or 40 degrees is generally reduced to about 15 or 20 degrees. If the demand is lower, the cooling tower can not be completed, and the refrigeration unit is required to complete it (chiller, some are also called chillers), and the inlet water temperature of the chiller can be room temperature, the outlet temperature can reach 50 5 degrees Celsius, and some cascade refrigerators can easily complete the temperature below 150 degrees.

This water is frozen water. Generally, in order to better improve the refrigeration power and energy-saving intention, the cooling water tower will be used for the first reason for refrigeration, and then connected to the refrigeration unit to output chilled water. The difference between hot and cold water is relative, mainly because of the setting of a defined value of temperature in the demand environment (operating conditions).

The coolant is filled into the water tank and can be called tank water. But the composition of coolant is not only water, coolant is composed of three parts: water, antifreeze, and additives. The full name of coolant is antifreeze coolant, which means coolant with antifreeze function.

According to the different components of antifreeze, it can be divided into alcohol, glycerol, glycol and other types of coolant. Ethylene glycol has a high boiling point and is not easy to evaporate and lose during use. Antifreeze prevents the coolant from freezing and bursting the radiator and freezing the engine block when the coolant freezes during the cold season.

Antifreeze isn't just for winter, it should be used all year round. In the normal maintenance program of the car, the engine antifreeze needs to be replaced every year of driving.

Antifreeze is a kind of coolant containing special additives, mainly used in liquid-cooled engine cooling system, antifreeze has excellent properties such as antifreeze in winter, anti-boiling in summer, waterproof scale and anti-corrosion throughout the year. Antifreeze also has the effect of anti-scale and descaling base, adding antifreeze in the water tank can remove the dirt in the water tank and protect the water tank. When changing antifreeze, it is generally necessary to clean the water tank, and if the brand of antifreeze changed is the same as the original car, it can not be cleaned.

Coolant is a new type of engine cooling medium, and its basic role is to dissipate heat from the engine.

However, traditional coolants: water and aqueous antifreeze cannot meet the congenital defects of engine heat dissipation

1. The water will freeze at 0, and the pot will boil at 100. Ice can inflate the engine's water tank and cylinder block, and boiling the pot can overheat the engine until it causes paralysis.

2. When the engine temperature reaches more than 80, water bubbles should begin to produce on the cylinder wall. Water bubbles form a bubble barrier layer on the cylinder surface, preventing heat from escaping from the engine. Water bubbles are endlessly formed and burst on the metal surface of the engine block, and the cylinder block is lost in a dripping effect This is cavitation.

3. The local temperature inside the engine is too high, and the pre-ignition and detonation tendency increases, which increases the vibration and noise, greatly reduces the performance and efficiency of the engine, and forms no water and fuel consumption.

4. Under the action of electrolyte, electrochemical corrosion occurs and rust and scale are produced, which aggravates the aging rate of the cooling system and reduces the heat dissipation performance.

5. When the engine temperature reaches more than 80, the water vapor, water bubbles and water body expand, which increases the internal pressure of the cooling system. In this way, it not only catalyzes the aging rate of the cooling system, but also makes it impossible to ensure the speed required for normal heat dissipation due to corrosion. Therefore, the heat dissipation defects of aqueous antifreeze are summarized as:

The heat dissipation performance is limited, and the overheated vertex cannot be suppressed; The engine gradually ages, so that the engine heat generation increases unabated; The cooling system gradually ages, so that the heat dissipation capacity is reduced but not increased.

It is recommended to use the latest product of coolant replacement: Huibang cooling oil, Huibang cooling oil can effectively solve the above problems and better maintain the performance of the engine. There is also the effect of saving fuel, more environmentally friendly! 500,000 km maintenance-free!
