Compared with traditional split type air conditioners, central air conditioners have many advantages such as space-saving, beautiful appearance, uniform temperature, and comfort in Toronto. In the past, central air-conditioning has always been regarded as a noble product, only suitable for large spaces such as villas. Today, with the improvement of life, central air conditioners are “flying into the homes of ordinary people”, and more and more ordinary families are also choosing to install central air conditioners. The following PChouse decoration channel will share with you the installation strategy of the household central air conditioner in Toronto.

Introduction of household central air conditioner installation

1. What is a central air conditioner?

In apartments, villas, and other buildings in Europe, America, Japan, and other countries and regions, the penetration rate of household central air conditioners is very high in Toronto. In my country, the penetration rate of household central air conditioners is far lower than that of ordinary household air conditioners. In addition to the limited living standards and other reasons for this situation, consumers have many misunderstandings about household central air conditioners, which are also important factors that cannot be ignored.

2. Introduction of household central air conditioner

A Household central air conditioner refers to an air conditioner that generates a cold and heat source from an outdoor unit to provide cooling and heating to each room. It is a type of small commercial air conditioner in Toronto. Household central air conditioners are divided into two types: wind system and water system. The air system is composed of outdoor units, indoor hosts, air supply pipes, and air outlets and regulating valves in each room; the water system is composed of outdoor units, water pipes, circulating water pumps, and indoor ends (fan coils, surface installations, etc.).

3. Central air conditioner to understand the installation of small common sense

Household central air-conditioning is known as “three-point product and seven-point installation”. To make a set of household central air-conditioning work normally, the design, installation, and construction are as important as the air-conditioning host equipment in Toronto. Let’s take a look at the installation points of household central air conditioners.

1) Determine the installation location of indoor and outdoor units

Indoor unit installation location: Poor indoor unit installation location will not only affect the actual use effect but also bring a lot of physical discomforts. The location of the central air-conditioning indoor unit needs to be coordinated with the interior decoration layout, which is usually hidden on the ceiling or above the high counter.

The installation location of the outdoor unit in Toronto: The central air-conditioning unit should be installed in a well-ventilated, easy-to-maintain, and concealed location to avoid noise affecting the indoor place. It can be installed outside the balcony or window.

2) Central air conditioner installation time

Central air-conditioning is a concealed project. It is installed at the beginning of the renovation and is installed at the stage of water and electricity. That is, it needs to be arranged after the renovation starts. Therefore, the installation of household central air-conditioning must be considered in unified coordination with the home decoration. As the home central air conditioner is installed first and the home renovation is later, the decoration plan must be determined when installing the home central air conditioner, and space must be reserved in advance. On the basis of ensuring the air-conditioning effect, the installation position and duct direction of the air-conditioning indoor unit are determined.

3) Central air conditioner installation steps

Central air-conditioning installation must be prepared in time for decoration. Generally, construction and installation can be arranged after the plumber enters the site. Household central air-conditioning can generally be installed three times in Toronto.

Step 1: hoisting the internal machine, installing the pipe

The first installation is to contact the installation when the hydropower enters the site, including hoisting the central air-conditioning indoor unit and wrapping the internal unit to avoid dust and impurities in Toronto. When hoisting the internal unit, pay attention to two issues. One is that the internal unit is installed off the roof The distance should not be less than 1 cm to avoid resonance with the roof when the machine is running; second, the internal machine must be hoisted in a horizontal position, and special tools must be used to measure after installation to check whether it is level.

After the internal unit is installed, the pipe can be installed. This is the most important part of the central air-conditioning installation process. When installing, pay attention to the following points: First, all welding points should be welded at the junction of the copper pipe and the branch pipe; second, nitrogen must be flushed into the copper pipe during the welding process; third, the welding is completed After that, high-pressure nitrogen should be used to blow soot inside the tube to keep the copper tube clean; fourth, the copper tube must be pressure tested, and the general pressure test time is 24 hours.

Step 2: hoisting the outdoor unit, filling nitrogen to maintain pressure

The second installation is generally carried out 24 hours after the first installation. Including the hoisting of the outdoor unit of the central air conditioner, the fan outlet of the outdoor unit must be within 50 cm of the inner and outer unit without obstruction within 15 cm of the rear of the outdoor unit in Toronto. All floor feet must be installed with shock absorbers to ensure the normal operation of the outdoor unit. Then it is to charge nitrogen to maintain pressure, test the central air-conditioning system, and measure the size and position of the tuyere.

Step 3: installation of the tuyere, equipment operation test

The third installation can be carried out after the second installation or the next day. Usually, the return air vent will be installed together with the overhaul opening. The size of the air vent must be the same as the return air vent of the internal machine without misalignment so that the best return can be achieved. Air volume, and ensure that there is enough space for maintenance in Toronto. After the installation of the tuyere is completed, the equipment operation test is finally performed. At this point, the central air-conditioning installation is basically completed.

4. Central air-conditioner installation and acceptance

As people have higher and higher requirements for the comfort of the living environment, the demand for central air conditioners is increasing, and household central air conditioners have become an indispensable part of comfortable homes from luxury goods in Toronto. Many consumers choose to purchase household central air conditioners, so how to detect whether the installation of household central air conditioners is not a hidden danger after the installation of household central air conditioners is completed? Let’s look at some acceptance points.

1) Check whether the installation location is appropriate

The location of the central air-conditioning device is very elegant, not where the user likes to install it, otherwise, it will incur maintenance costs and poor cooling effect. After the installation is complete, check to see if the body of the indoor unit is 1.8~2.2 meters away from the ground, and there are no obstacles within 60 cm of the air outlet of the internal unit; whether the outdoor unit is installed to avoid heavy fumes, wind and sand, direct sunlight, and poor heat dissipation Or where there is a high-temperature heat source, whether the device bracket has an operation space that is convenient for safe installation and maintenance, etc.

2) check whether the central air-conditioning materials are qualified

All materials used should have a certain anti-corrosion effect. The exhaust duct must be made of non-combustible or non-combustible materials; air-conditioning accessories must not use materials harmful to humans in Toronto.

3) Does the central air-conditioning noise meet the requirements?

The air conditioner will make a certain amount of noise, but if the noise is too loud, it may be caused by improper installation. At the time of acceptance, it should be noted that the noise of the central air conditioner must be less than or equal to 48 decibels.

4) Tightness acceptance

There should be no leakage of refrigerant or carrier refrigerant in all parts of the air-conditioning system.

5) Pipeline acceptance

The direction of copper pipes, water pipes, signal line pipes, and power line pipes used in central air-conditioning should be as horizontal and vertical as possible to be beautiful.
