Now it is difficult to imagine houses or apartments without such cooling device as an air conditioner.
In apartments, as a rule, split systems are installed on the base of one outdoor unit and one indoor unit. In the houses, on the contrary, an air-conditioning system is commonly organized with a multi-split system – one outdoor and several indoor units of any type. When each of these systems is qualitatively designed and properly installed, there are no difficulties with the efficiency of its operation.
But there is a number of cases when the air conditioning system fails: when people are not fully satisfied with the climate control system, or even worse – it starts to irritate the residents.
Does it sound familiar to you: after a long-awaited installation of an air conditioner, you can notice a malfunction in its work? It can be:
The primary solution in such cases will be the verification of project designing documents and the quality of the installation work (see Table 1).
As practice shows, in most situations, mistakes lie in the negligence in the work of the company that designed and installed the system. Here are a few cases where miscalculations are most commonly noticed.
At the stage of designing, such moments have to be fully calculated, because the appropriate equipment is determined by capacity, productivity, and a set of useful functions. A combination of these omissions leads to malfunctions of the air conditioning system and negative consequences both for the system itself and its owners.
Table. 1 – Example of a design and technical documentation for determining heat inflows.
Example: A company incorrectly did the calculations and installed the air conditioner. The actual amount of heat input into the room is 5 kW. But these so to say «specialists» chose equipment with a cooling capacity of 3.5 kW. As a result, when the air temperature outside reaches high values, the air conditioner will not generate enough cold for a comfortable indoor microclimate.
What I offer you is a heat engineering recalculation that is carried out directly at the object. It includes statistics on all heat inflows into each room and only then, on its basis, we select proper equipment.
In a few words, the optimization of the finished air conditioning systems is a series of measures aimed at increasing the efficiency of its operation.
It is possible to detect the lack of a cold from the conditioning system in a project documentation. But there are cases where all the preliminary calculations have been carried out correctly, but there is still not enough cold. In this case, it is worth considering technical problems of the conditioner itself. The efficiency of the equipment is also highly affected by the maintenance and service. It is necessary to check the filters – they can be clogged and it causes a bad air exchange.
Also, the problem can be in the refrigerating circuit itself: the leakage of Freon leads to the low pressure in the system. The compressor cannot operate normally and as a consequence, the air conditioner does not produce the required amount of kilowatts of cold.
Replacement and elimination of failures are what is considered to be modernization of the finished and installed air conditioning system based on indoor units of the wall type.
When analyzing such system, it is necessary to take into account aerodynamics. What is it?
Aerodynamics is a cross section of air ducts from the channel conditioner, which are laid in the under-ceiling zone. Therefore, when optimizing, it is necessary to take into consideration the air distributors (diffusers and grilles), and also check whether correctly or not the air ducts were selected in terms of speed and cross-section.
The next question, which is closely related to the channel conditioning system, is connected with noise indicators. And when the noise level begins to irritate, that is the first and only sign that shows that your system needs to be upgraded:
What we offer is the solution of such problems by replacing air ducts, grills, diffusers according to your specific system.
Any client who has a problem with the air-conditioning system should understand that any issue can be solved, the only question is the price and the cost of measures aimed at the problem solving.
Therefore, the basis of everything is design. In order to correctly implement the air-conditioning system, it is highly necessary to find a competent company that will design and will be fully responsible for the result. Everything can be solved. But the question is in price and time: you can do only cosmetic repairs, and you may need a complete rework of the system.
Hence, I am ready to analyze possible optimization or modernization of the finished air-conditioning system of any difficulty. And I guarantee to provide you with clear arguments on every point, in other words, what should be done and what the consequences will be. The list of tasks and a number of measures are given in the form of a commercial offer that contains a technical solution and an economic justification.
