For installation of any equipment, we must first prepare the materials tools and equipment thus ensuring that the installation takes place in an agile and organized way. The first stage of the work is the site preparation. At this point we must mark the position of the machines according to the project received. In the absence of a project we must follow what is stated in the equipment manual.
We chose the best position for the evaporator and condenser units. To do so, we must think of the way of passage of the copper pipes for interconnection of the units and the way of installation of the drain. We verify the availability of power points and analyze the physical structure available at the installation site to verify that it supports the weight of the units. All this will position the internal and external units. The condenser unit (external) is connected to the evaporator unit (internal) through a copper pipe and an electric cable that ensures the connection of the control and power circuits between the units. For interconnection of the refrigerant circuit between the units a copper pipe is used, the diameter of which is defined by the capacity of the system, the length of the pipe and the unevenness between the units. Once the diameters, lengths and risers have been defined, we can install the pipes.
First we mark the path of the pipes and we provide the necessary procedures for the passage of this pipe. Afterwards, we must carry out the preparation of the pipes, with procedures of welding, checking of tightness and thermal insulation. Welding procedures, line pressurization for leak testing, internal cleaning and pipe insulation should preferably be performed off-site. This reduces the possibility of damage to the material, the environment to be air-conditioned and guarantees more safety for the installer.
Depending on the position of the evaporator and condenser units, we must predict the installation of siphons, which will have different purposes depending on the positions.
