Is the central air conditioner called light steel or wooden keel? Triangle iron is generally used for central air conditioning hoisting, which involves light steel and wooden keel. Light steel keel should be used for the ceiling, and wooden keel should be used where tuyeres need to be installed, because wooden keel is easier to fix tuyeres.
How to install the air inlet, sealed air outlet and inspection port of central air conditioning? When installing, the outdoor unit should be as close as possible to the indoor unit, so as to shorten the refrigeration process pipeline and lower than the indoor unit as far as possible, and the height difference is generally within 5000mm; If possible, it should be installed on the floor or on a fastening platform that will not produce noise. Rubber shock absorbers or rubber strips with a thickness of 10mm shall be set under the base to keep the outdoor unit running stably.
In order to make the outdoor heat exchanger have good heat exchange conditions, the air inlet and exhaust should be unobstructed to avoid backflow, and a gap of more than 200mm should be left on the side of the outdoor unit against the wall;
For example:
1, when installed off the street, the bottom of the unit must be above 2500mm from the ground, so as not to hinder traffic and pedestrians; The hot (cold) wind discharged from the outdoor unit should not be aimed at neighbors or passers-by at close range, and guide fence plates should be set if necessary; In the coastal areas where air pollution and acid rain are serious and the air contains more salt.
2. Prevent the outdoor unit from rusting, reduce the service life of the air conditioner, and at the same time, in order to avoid direct sunlight and improve the refrigeration effect of the unit, a sunshade curtain should be set without hindering the air circulation; When installed on the upper floor of a prefabricated building, the drainage of outdoor units (defrosting water when using a heat pump), including the condensate of indoor units, should be connected to the centralized sewer pipe of the building so as not to affect the normal life of downstairs and passers-by.

The temperature difference between the air inlet and the air outlet of the new air conditioner is different, because the preconditions are different.
For example, when the actual indoor temperature is about 20 degrees and the outdoor ambient temperature is about 7 degrees, the air conditioning system is normal, and the outdoor air temperature should be above 35 degrees when the indoor unit is running in the gale. That is to say, the temperature difference between inlet and outlet is above 15 degrees.
How much is the home central air conditioner? Installation fee, copper tube fee, air inlet and outlet fee? Installation fee, copper tube fee and air outlet shall be charged separately.
Yes, these manufacturers don't deserve it, and they need to pay extra. In fact, the price gap between home central air conditioning and home split air conditioning is here. In fact, the prices of air-conditioning machines themselves are similar, and some are still cheap. Some manufacturers of household air-conditioning machines settle accounts for dealers, but the installation materials must only be paid by themselves!
