Hydropower and Air Conditioning
First, the water supply pipeline
Second, power lines
The power lines are mainly used for artificial lighting and electrical appliances. The following will talk to you about some of the relevant knowledge:
Most of the newly-built house wires are now impossible, and 100% of the renovations that I took are to be re-laid. The general criteria are:
1, the main line with 2.5 square millimeter copper wire;
2, air-conditioning line to use 4 square millimeters, and each air conditioner is to be individually routed;
3, telephone lines, television lines and other signal lines can not be parallel with the wires.
4, the use of protective plastic wire boxes, buried in the wall to use the hose (including pvc tube), the interface must use straight / elbow. If you can not use the hose, you must use a metal hose to protect it.
5, to buy wires, switches, etc. must buy good goods, the only mark is whether it meets national standards. At the time of purchase, the dealer should indicate this.
Third, air conditioning system
The renovation of the house will inevitably require an air conditioning system. This includes cooling and heating. Here to talk about refrigeration, cooling the main means at present is the air conditioner. Of course, I do not intend to call everyone to install air conditioners on their own. This is not very realistic, and manufacturers or suppliers have provided installations. Here are the relevant notes.
1, the purchase of air conditioners. Try to use brand-name goods, really, buyers must buy brand-name, otherwise the hand can be long. As far as possible to buy a large business with a reputation, it is best to buy direct manufacturers to buy. Remember to keep the warranty card and related invoices.
2, the number of horses should be appropriate. The number of horses is related to the intensity of cooling. The number of air-conditioned horses in the living room should be slightly larger to allow room for power. There are 0.5 to 1 horses in the bedroom and 1.5 in the living room.
3, a simple program.
1) Delimit the installation position mark.
2) Make a variety of holes on the wall or floor. If the pores pass through the wall, a hose can be cut and the gap can be sealed with cement.
3) Install brackets or hangers.
4), calibration position.
5) Follow the instructions for the installation procedure.
4. Repeat again here, please be sure to use the 4 square line as the air conditioning power supply line, and take a single circuit.
Unlike cooling, the heating section is now rich. Including air conditioner heating, pipe heating, floor heating and other forms:
1, air conditioning heating. This heating method is mainly used in some southern regions where the temperature is not low. Its main advantages are warming, but it can also be hot and cold. Similar methods include heaters, radiant heaters, and so on. This kind of heating method is aimed at a specific house, and it is generally difficult to take into account the heating problem of the entire household.
2, pipeline heating. Pipeline heating is provided by a municipal heating plant that provides heat from coal-fired boilers and heatsinks through a centralized pipeline to the indoor heat sink. Because coal-burning pollution is serious, the cleaner method is to use natural gas for fuel, but it is also relatively necessary to increase the related costs.
This kind of heating also has an undesirable consequence, that is, vertical and horizontal pipes will affect the interior appearance and reduce the actual indoor use area by about 3%.
3, household wall heating stove. This method is to create a heating stove for each household and heat it by means of a wall-mounted radiator. The main fuel is natural gas or liquefied petroleum gas.
4, floor heating. This method is similar to the heating method of the heating stove. The difference is that it transports thermal energy through pipes laid under the floor instead of through the radiator. Compared with other heating, it has more aesthetic advantages because it does not see pipes. Its disadvantage is that it needs to occupy a certain height, and there is a requirement for the thermal insulation of the floor decoration material. Some decorative materials with good insulation properties are not suitable for such indoor flooring.
5, electric heating. Electric heating is more environmentally friendly and has more detachable operability. Its greatest drawback is the high demand for electricity, which is difficult to implement in some cities that lack electricity. And this kind of heating method has high requirements for indoor insulation, and its use cost is quite high. Beijing and other big cities are experimenting with this type of heating.
Under certain conditions of heating, the right of decision is in the hands of the house developer, but we can believe that environmental protection, energy saving and low-cost heating will continue to emerge.
