Which machine to install on the air conditioner

The performance and energy efficiency of your air conditioner can be greatly impacted by selecting the appropriate machine. Knowing your options is essential whether you’re installing a new system or upgrading an old one. This guide will take you through each machine that is available and assist you in selecting the one that best suits your needs.

There are various types of air conditioners, each intended for a particular use and area. Window units, split systems, portable units, and central air conditioning systems are among the most popular varieties. Making an informed choice can be aided by being aware of the benefits and drawbacks of each type.

Popular for cooling individual rooms are window units. They are inexpensive, simple to install, and appropriate for small homes or apartments. Conversely, split systems work well for cooling several rooms. They offer greater efficiency and flexibility because they are composed of one or more indoor units and an outdoor compressor.

For individuals who require a temporary cooling solution, portable air conditioners are ideal as they provide mobility. These units are suitable for a variety of spaces because they can be easily moved from one room to another. The most complete option is a central air conditioning system, which can cool an entire house. Although they require more money to install, they provide more reliable temperature control and superior air quality overall.

A few things to think about when choosing which machine to install are the size of the area that needs to be cooled, your financial constraints, and your long-term energy efficiency objectives. To ensure comfort and efficiency all year long, choose the type of air conditioner that best suits your needs. Each type has specific advantages.

Why does the air conditioner need a separate machine?

After purchasing, you should read the instructions, making sure to understand how to connect the power supply.

  • Which screwdriver to choose for home work
  • How to turn on an air conditioner without a remote control
  • How to turn on the air conditioner for cooling
  • Which fence to choose?
  • What paint to paint the ceiling in an apartment
  • Which laminate to choose?

Proceed if the user manual explicitly states that the device needs to be fed from a different line.

If you violated the connection requirements and have a split system issue, the seller may refuse to provide a guarantee on that basis.

The option is yours in the event that there isn’t one, but you should weigh the benefits of having a separate wiring first:

  • You can install a split system with high power even in houses with old and aluminum wiring.
  • A system with a separate automatic machine does not have a negative effect on other devices in the house. The starting currents of its compressor and fans are high and during the old wiring can be disabled other devices.
  • There is no need to install a socket for connection, you can connect through a camshaft.

The likelihood of the need for separate wiring increases with the air conditioner’s power.

Since other materials aren’t really used at the moment, let’s take copper cables as an example.

The first thing you should be aware of is how much power a split system uses (it is advised to consider the maximum starting current). It is important to choose the wire’s cross-section with this power in mind. And the desired machine is selected only based on this section.

There are sufficient square conductors with a 1.5 mm cross-section for air conditioners with a capacity of no more than 2 kW, as demonstrated by calculations and practical experience with models 7, 9, 12, and 18. For "24" and "36" (single-phase), a 2.5 mm section is preferred.

To ensure ease of understanding, these values are shown in tabular form.

What power of air conditioner do you install??

As you can see, only two cable cross-sections are typically used in household split systems, necessitating the use of appropriate circuit breakers. Although selecting a circuit breaker with a lower rating can be recommended, we do not advise doing so. In summary, a device with this rating will undoubtedly "protect" the cable, whereas a device with a lower value might shut off early.

The characteristics of the circuit breaker are indicated by the letter preceding the digital value. Class C circuit breakers, which are "resistant" to moderate starting currents and perfect for installations with split systems, are the most widely used circuit breakers in private homes.

If you choose a class A or B circuit breaker, for instance, they might trip when the compressor operates.

There are also a lot of machine manufacturers on the list. It can be separated roughly into two sections:

You must comprehend how these devices operate in order to respond to this question.

The current passing through the phase cable and the zero is continuously measured by the RCD. The RCD will cut the power if a leak happens and the difference between these currents is greater than 30A, which is a current that is no longer safe for human life.

They lack internal safeguards against high current or short circuit current. However, the RCD detects that the current through the neutral conductor is less than the current through the phase if someone grabs hold of the wire and current starts to flow through it. It switches off the network if the difference is greater than 30 mA.

There are two fuses in the machine:

All devices (RCD and machine) are present simultaneously in the differential machine. A split system connected via an automatic switch requires less space in the distribution box. An additional benefit is the simplicity of connection.

Experts advise combining RCDs and circuit breakers. particularly when there are several devices that require security. Since the RCD costs less than the automatic device, you will then be able to save money. It is possible to install one machine at the entrance and one RCD for each direction, or the other way around—one machine for the subnetwork and one RCD for the entire network.

The only automatic machines with an indication that the RCD has tripped are the expensive ones. In less expensive ones, it is impossible to determine if the leakage current was excessive or the short circuit breaker tripped.

Examine the following option: 3 RCDs and 1 automatic machine. The RCD’s instantaneous trigger indicates which line has failed. Turn on the circuit breaker after turning off all RCDs if the breaker has tripped. Next, turn each RCD on individually. The location of the fault is where the machine is triggered when the RCD is turned on.

Installing a single two-pole difautomatic circuit breaker is more practical when the air conditioner has its own power line. Phase and neutral wires need to be run through it for proper operation.

Machine installation process

Ascertain ahead of time which line the split system needs to be connected to. You can connect to a free outlet if the power is low and the instructions don’t state otherwise. We will undoubtedly inspect the branch that runs from the distribution panel to the outlet first.

  • tighten the screw connections on the socket and circuit breaker;
  • check for oxides on the connections in the splitter block, clean the contacts if necessary;
  • make sure that the split system plug is tightly inserted into the socket and does not wobble.

Consult the air conditioner’s instructions if you must lay a separate branch. Typically, it shows the currents that the circuit breaker needs to be designed for. If not, kindly choose it according to the hardware’s capacity.

Decide where you want the Difavtomat to be. It has to be installed at the location where the protected line splits off from the supply, per the regulations for electrical installations.

The distribution panel at the apartment or house’s electrical line entrance is the ideal location.

  • The cross-section of the wires in the laid branch must be no less than the cross-section of the wires going to the split system.
  • The rating of the main line machine must be greater than the rating of the machine on the auxiliary line.

Installation of equipment

  1. The machine must be installed on a DIN rail.
  2. Connect the phase wire (it can be of any color) to the upper connector of the new machine and to the lower connector of the input.
  3. Connect the phase wire going to the air conditioner to the lower connector of the new machine.
  4. The same procedure must be performed for the neutral wire (usually blue or black).
  5. To avoid errors, the phase is usually controlled with a special indicator screwdriver.
  6. The third wire (green-yellow) must be connected to the grounding bus or bolt of the distribution cabinet.

According to safety regulations, only qualified electricians may perform any electrical work.

Selecting the appropriate unit to install on your air conditioner is essential to guaranteeing effective and efficient cooling. The window AC, portable AC, and split AC are the primary options to think about. It’s crucial to consider each type’s advantages and possible disadvantages in light of your unique requirements and situation.

Split air conditioners are well-liked for both their visual appeal and quiet operation. They are perfect for homes where you want a discreet, long-lasting fix. They can be more expensive initially and require professional installation. However, window air conditioners are more affordable and easier to install, which makes them a good option for temporary or smaller setups. The drawback is that in bigger spaces, they might be less effective and noisier.

The most flexible option are portable air conditioners, which can be moved from room to room as needed. They are therefore a flexible option for tenants or people who might move around a lot. They can take up floor space and generally don’t cool as effectively as split or window units, which may be a factor for some users.

The ideal air conditioner for you will ultimately depend on your unique needs, which may include the size of the room, your financial situation, and whether you require a temporary or permanent solution. By taking the time to weigh the advantages and disadvantages of each choice, you can make an informed choice and guarantee that your area is comfortable all year round.

It’s important to take efficiency, compatibility, and ease of use into account when selecting a machine to install on your air conditioner. The proper appliance can greatly improve the efficiency of your air conditioning system, guaranteeing more effective cooling, reduced energy costs, and an extended lifespan for the unit. Making an educated decision that keeps your home comfortable and your air conditioner operating efficiently will depend on your understanding of your needs and options, whether it’s a straightforward thermostat upgrade or a more involved inverter installation.
