Selection criteria for a system
Each establishment has a number of critical determinants in the process of choosing a solution from a cooling for your study. Some issues to consider are:
When adding a studio to an existing facility, what Is infrastructure available to make the project fit?
Do we need an autonomous system or is there a refrigeration available?
Is this studio part of a new facility planned, in where a global cooling strategy is being considered and a ventilation system?
What is the initial cost of various system options when balanced with a trade and pricing analysis?
What is the appropriate scale for the project?
What are the aspects related to maintenance and reliability?
Let's start by looking at some basic premises about the air conditioning systems. This type of air is based in a fan that blows through a coil, which has a coolant or water in a closed system to absorb heat of the air and be expelled, so it refreshes the environment with the discharge from the side of the coil. The heat that absorbs the coolant or water is transported by means of pipes to a condensation section, where it releases the captured heat and the cycle begins again. There are systems that use mixtures of water as a means of heat transport, but only in Special occasions are considered a solution. The most used is that of refrigerant.
There are two types of basic systems that use refrigerant: DX and cooling. DX (direct expansion) is they call it this way because the evaporator is in direct contact with the air current, making the cooling coil and the evaporation cycle are the same. In the other system of cooling, cold water is produced and used as a means of heat transfer from fans in construction to the outside to expel heat.
In any case, choosing a system should be done together. with consulting engineers and architects, since the Answers to the questions raised by the above should be calculated in the context of a complex series of variables.
