How much power does a 300 square meter multi connected air conditioner use? What equipment is includ

Air conditioners have nameplates, there is a current value on them, the air is mainly short-circuit protection, choose one point and five times, the error point is fine, the wire selection is also based on the current, this is complicated, because the conductivity of different wire diameters is different.

Estimation formula: 2.5 times 9, subtract one straight up and go.

Thirty-five times 3.5, double in a group minus five.

The conditions have been changed and converted, and the high-temperature nine-fold copper has been upgraded.

The number of pipe roots is two, three, four, eight, seven and six folds full of load current.

Note: 1) The current carrying capacity (safety current) of various insulated wires (rubber and plastic insulated wires) is not directly indicated in this formula, but is expressed by "multiplying the cross-section by a certain multiple", which is obtained by mental arithmetic. As can be seen from Table 5-3:

The multiplier decreases as the cross-section increases.

2.5 times by nine, up minus one by one line" is talking about 2 5mm' and below various cross-section aluminum core insulated wires, the current carrying capacity of which is about 9 times the number of cross-sections. For example, 2 5mm' wire, the current carrying capacity is 2 5 9 22 5 (a). The relationship between the current carrying capacity and the number of cross-sections of the wire from 4mm' and above is to go up along the wire number, and the multiple is gradually reduced to L, that is, 4.

Thirty-five times three .five, double and double groups minus five ", which means that the current carrying capacity of the wire of 35mm" is 3 5 times the number of cross-sections, that is, 35 3 5 122 5 (a). From 50mm' and above wires, the multiplier relationship between the current carrying capacity and the number of cross-sections becomes two two wire numbers in a group, and the multiples are subtracted by 0 5 in turn. That is, the current carrying capacity of the mm' wire is 3 times the number of cross-sections, and the current carrying capacity of the mm" wire is 2 5 times the number of its cross-sectional area, and so on.

The conditions have been changed and converted, and the high-temperature nine-fold copper has been upgraded. The above formula is based on the aluminum core insulated wire and the open application at an ambient temperature of 25. If the aluminum core insulated wire is laid in an area where the ambient temperature is higher than 25 for a long time, the current carrying capacity of the wire can be calculated according to the above formula calculation method, and then it can be discounted; When using not aluminum wire but copper core insulated wire, its current carrying capacity is slightly larger than that of aluminum wire of the same specification, and the current carrying capacity of one wire number can be calculated according to the above formula method.

For example, the current carrying capacity of 16mm' copper wire can be calculated as 25mm2 aluminum wire.

The 300-square-meter air conditioner with Daikin ** air conditioning costs about 120,000.

If Gree's should be 125, a 5 hp machine with a power consumption of 290W and a cooling capacity.

The use of one tow and one air duct machine: about 130 yuan square meters Water machine: about 200 yuan square meters.

Multi-online: about 300 yuan square meters.

The above is only a reference data, and the actual expenditure needs to be determined according to the actual situation.

The amount of power is related to the equipped model.

For 300 square meters of workshops, air conditioners are divided into two categories. The effect and cost are not the same.

One is traditional air conditioning

If the workshop is well sealed, and the production process does not produce too much heat and odor, then the traditional air conditioner (Midea, Gree) is more effective, the cooling is obvious, but the electricity cost is relatively high, and the electricity consumption is about 8 kWh per hour.

This air conditioner is used for 300 square meters, about 90,000 yuan on the ground, and consumes 24 kilowatt-hours of electricity per hour.

The second type is environmental protection air conditioning (also known as industrial air coolers):

This type of air conditioner is not a traditional air conditioner, without a compressor, but uses water evaporation to absorb heat, and conveys a large amount of cool breeze to blow people and equipment.

Better ones such as: Keruilai, Jiafeng, Aollan, etc., can be used in most of the open production workshops, improve the high temperature at the same time, fresh air can also improve the odor.

This air conditioner is used for 300 square meters, the landing cost is about 30,000 yuan, and the power consumption is about 3 kilowatt-hours per hour.

The power consumption of 100 square meters is about one kilowatt-hour, and in terms of input cost and use cost, this kind of air conditioner is more suitable for factory cooling.

That's going to be hundreds of thousands of air conditioners.

It is recommended to use the inverter multi-connection air duct machine specifically** yourself to ask a few more.

The air conditioner Gree is the best, the water heater is the best Smith, and I use it at home.

One card = and then it depends on what your venue is used for. Residents generally need 100 to 12,600w per square meter, which means 126 to 84 square meters. The size of the hotel should be halved.

The bar load is larger, generally 300w per square meter, so it is 180kw, a horse is 2300-2500w, calculate it yourself, how big the host is.

An external machine of about 40p is fine!

It's the same I'm the one who makes ** air conditioners, and calculates the installation fee for the owner.

It is also according to the number of indoor units, but we report the auxiliary material fee and the installation fee together, and an indoor unit is 1500 yuan (including materials and installation).

It's pretty much the same here in Wuxi. However, we package about 400-420 units of labor, and 1200---1400 units of materials. The money is counted separately from the machine.

I'm charging for it. Labor costs are included. Copper pipes are charged separately.

Now 1,000 yuan per unit, contracted labor and materials.

What year's **, 10 years ago.

If a 300-square-meter house is equipped with **air conditioning, it needs about 50,000-80,000**.

1. **The air conditioning system is composed of a cold and heat source system and an air conditioning system. The principle of liquid vaporization refrigeration is used to provide the required cooling capacity for the air conditioning system to offset the cooling load of the indoor environment; The heating system provides heat to the air conditioning system to offset the heat load of the indoor environment.

2. The refrigeration system is a vital part of the air-conditioning system, and its type, operation mode, and structural form directly affect the economy, efficiency, and rationality of the air-conditioning system in operation.

The Japanese and American systems are about 300 or more, and the domestic 200 can be controlled, but it still depends on what system, fluorine is more expensive than water in the early stage, but it is still recommended to use fluorine.

Water system** Estimated cost of air-conditioned dwelling, ranging from 200 to 350 per square meter, and fluorine system ranging from 100 to 200 per square meter.

If you have multiple connections, the minimum per square meter is about 300 (air-conditioning area), and you can save a little if you have a water machine, because the main engine of the water machine does not need to be too big, and the end is very cheap. It also depends on the brand you choose, domestic will be cheaper, such as multi-online can choose Gree, Midea, foreign choose Daikin or Mitsubishi Electric, the difference between the two is 20-30%, the water machine uses York or Gree, the quality is very good.
