How many liters of antifreeze do you need to add to a balcony wall mounted solar water heater at one

Hello, very high Sun Mu is happy to serve you, the wall-mounted water heater needs about 10KG left and slippery right to achieve the effect. The antifreeze can not be too thick, there is a nozzle under the water tank, connect the pipe to the top to open the valve, and press it in, I hope it can help you, then I wish you a happy life.

Can you use a different brand of antifreeze?

The wall-mounted solar water heater on the balcony of my house has been sunny for several days in April, and the water temperature is less than 40 degrees.

The functions of car antifreeze are:

1. Prevent the coolant from freezing and cracking the radiator and freezing the engine cylinder block or cover when parking in the cold winter.

Its main indicator is the freezing point of the antifreeze. When selecting or formulating the antifreeze, its freezing point should be about 10 below the minimum temperature in the region to ensure that the antifreeze does not freeze in exceptional circumstances. Another important function of antifreeze.

Its main indicator is the boiling point. The boiling point refers to the condition that the coolant begins to heat up to the control temperature of boiling under the condition that the cooling system of the automobile engine is in equilibrium with the outside atmospheric pressure, and the engine is kept working at normal temperature. Antifreeze also provides protection against corrosion.

Corrosion is a remote process in which metals are destroyed in the natural environment due to chemical reactions, electrochemical processes, and physical uses. At present, there are six main anti-corrosion metals, namely: steel, cast iron, copper, solder, brass, and cast aluminum.

Most of the cooling systems of modern automobile engines are made of cast aluminum and aluminum alloy parts, so the focus of antifreeze corrosion protection should also be shifted to anti-corrosion of aluminum, and the dissolution, bulging and aging of non-metallic materials such as rubber and plastics in the cooling system should also be considered. Corrosion inhibitors are substances that stop or slow down these processes. Another important function of antifreeze is waterproofing, which is caused by the attachment of insoluble salts or oxide crystals to the surface of the radiator.

After the scale is generated, it not only affects the normal heat dissipation of the radiator, but also is more likely to cause the blockage of the circulation pipe of the cooling system, and the water temperature is too high and seriously affects the normal operation of the engine. The main substances that can produce limescale in the cooling system: calcium sulfate, calcium carbonate, magnesium carbonate, etc., as well as brown calcium phosphate due to improper use.

Calcium and magnesium ions mainly come from the water in the coolant, so the water quality of the cooling antifreeze must be strictly controlled.

Second, the requirements for adding coolant.

According to the structural characteristics of the engine, the manufacturer has made strict requirements for the use of coolant for the engine, and has clear requirements for the general use of long-term antifreeze and antirust liquid. Due to the lack of experience in the performance of antifreeze, the water quality requirements for adding cooling water are not strict, which will cause fouling in the waterway, affect the normal circulation of engine cooling water, and reduce the cooling intensity, so that the engine temperature is too high, reduce the power, increase fuel consumption, and reduce the service life of the engine.

It is even more important to use long-lasting antifreeze as much as possible, and to pay attention to the quality of antifreeze.
