Air conditioning was invented in the United States in 1902 by engineer Willis Carrier. He created an innovative device for a major New York printing company.
Such a system was intended not only to protect the printing house employees from high temperature in the room, but also to effectively combat high humidity.
Quick reference
In the mid-twentieth century, portable air conditioners began to be produced, which were intended for one room. They began to call them "window". For the first time, the creation of such exhaust devices began to be dealt with in the USA and Japan, and a little later, production also appeared in European countries.
Installation of such devices was quite simple, did not involve the use of any special equipment. And now window air conditioners are produced in large quantities, they are necessary for countries with hot climates.
Split system
In 1961, a split system was developed, which became a big step in the development of the air conditioning industry. Japanese engineers managed to split the air conditioner into two blocks. The indoor unit was placed inside the room, and the compressor (external part) began to be installed on the street.
First, such split systems were created in which the indoor unit was placed on the wall, and then new models appeared in which the split systems had an internal part in the form of ceiling, column, floor, cassette and channel options. Repair of an air conditioning system of this type was carried out by companies manufacturing this equipment.
Then came the multi-split systems, which were air conditioners, where there was one external unit, and several indoor units were allowed at once. Japanese development engineers have created a VRF system that can replace the entire central air conditioning system.
The device is a modern air conditioner
A compressor works in a split system, creates a vacuum. It, in turn, forces Freon to move in a circle. Gas evaporates, taking heat in the indoor unit, gradually turns into liquid, in the outdoor unit gives off heat. If they include a split system for space heating, the blocks change their functions.
Some models of air conditioners are additionally equipped with filters for fine cleaning. They help cleanse the air of the smell of cigarette smoke, allergenic pollen of flowers and even the smallest dust.
The need for inspections
Repair and maintenance of air conditioning systems is a mandatory measure. It allows you to timely detect various technical problems, correct them.
Repair and maintenance of ventilation and air conditioning systems is a prerequisite for the operation of these systems, because in case of equipment malfunction, there is a threat to human health.
Causes of malfunctions
In what situations is air conditioning repair necessary? The efficiency of the ventilation system can be reduced for various reasons:
with clogging of one or more ventilation ducts;
in case of breakdown of equipment or its individual elements;
in case of clogged filters or other components
The signal that the air conditioning system needs repair (maintenance) is condensation that appears on the mirror or walls, the spread of odors around the house, stagnation of air in the rooms.
Such phenomena indicate an insufficient amount of fresh air, are an indicator of the ineffective operation of exhaust ventilation.
Before you start repairing the air conditioning system, you can bring a sheet of paper to the ventilation grill. Depending on its fluctuations, one can judge the quality of the ventilation system.
Work options
At what intervals is it necessary to repair ventilation and air conditioning systems? The frequency depends on the following factors:
power;
type of system;
type of equipment;
destination premises
Maintenance of the ventilation system in an apartment building and a private house has significant differences.
Repair of air conditioning systems involves the following activities:
Maintenance is carried out only by experienced professionals. In the absence of high-tech equipment in the system with a complex network of ventilation ducts, independent monitoring and maintenance of ventilation devices is allowed. When cleaning exhaust systems and supply valves, you can not involve specialists.
Maintenance Schedule
It is usually the organization that designed and installed ventilation equipment that deals with it. After signing the act on the installation of the air conditioner, it is advisable to conclude an agreement on the maintenance of the system.
In this case, the responsibilities are assigned to the organization that carries out the installation and configuration of the air conditioner. The service organization, which has a license to carry out this type of work, is engaged in its maintenance. In an apartment building, ventilation ducts are serviced by a management company.
A standard maintenance schedule has been developed that defines the list of works related to ventilation maintenance, the frequency of individual nodes:
to a heater;
to the fan;
dampers;
electrical modules;
controllers
filter elements
Among the events held with air conditioning, of interest are the works that are carried out daily:
external inspection of equipment;
taking readings of air intake on the supply devices, recording them in the logbook;
checking the system for contamination, damage, leaks;
assessment of the quality of fixation of equipment;
control of pressure and temperature of the heat carrier;
electrical connection analysis;
drainage cleaning
In addition to the daily inspection, a weekly assessment of the filters, the direction and speed of the fans, the tension of the belt drives is expected.
