Used split air conditioner unit

Types of used split air conditioner units

A used split air conditioner unit has two major parts: an inside part and an outside part. The inside part is called the evaporator, and the outside part is called the condenser.

Used split ACs come in three main types:

• Wall-mounted units:

  This is the most common type of indoor unit. It is a sleek AC mounted high on the wall of the room. Wall-mounted split ACs are better for homes and offices with limited floor space. It also gets better air distribution since it is mounted higher on the wall. Wall-mounted used ACs also come in various designs and sizes to match any decor. Some models even come with inverter technology that allows for variable-speed compressors.

• Ceiling-mounted cassette units:

  This design looks just like a ceiling light fixture. It is best for commercial buildings with large areas and low ceiling heights. Ceiling-mounted cassettes evenly distribute cool air in four directions. Some models come with motion sensors that automatically change the air distribution based on the room's occupancy.

• Floor-mounted units:

  Floor-mounted ACs are larger than wall-mounted units. They can be placed along the floor instead of the wall. They are best for rooms where installing a wall-mounted unit is inconvenient. Floor-mounted units are also ideal for commercial spaces with high foot traffic, as they can tolerate more wear and tear than wall-mounted units. They are also better for older buildings with less wall space.

• Inline ducted units:

  Inline ducted split ACs have only indoor parts. They are best for people who want invisible air conditioning. The indoor units are installed inside the ceilings or walls to distribute cool air through ducts and vents. Ducted units are also good for larger homes or offices with multiple rooms, as one unit can control the temperature of several spaces.

Function and Features

Used split system ACs have various features that make them effective, convenient, and efficient. With the right usage, these features improve the overall air conditioning experience while maximizing efficiency.

• Heating and Cooling

  Some split air conditioning systems can cool down a space and heat it. Units with the reverse cycle feature can change the flow of refrigerant. In heating mode, the outdoor unit collects heat from the air and moves it into the room. When it's cooling, it draws out the heat and releases it outside.

• Remote Control

  Most used split ACs are convenient and easy to use. They have a remote control that lets the user change the temperature, mode, fan speed, and set a timer without moving from a comfortable spot. Some manufacturers make the remote with large buttons and an ergonomic design.

• Multiple Indoor Units

  Some split AC manufacturers design their systems to be flexible and adaptable. The multiple indoor unit configuration lets one outdoor unit connect to various indoor units. Businesses and users can install multiple indoor units in different rooms or areas. Each unit has independent control. Users can set different temperatures and modes. At the same time, the system reduces installation costs and saves space. Users and installers can use the appropriately sized indoor unit for each room. The system works well for areas with limited outdoor space to install the outdoor unit.

• Timer and Sleep Mode

  Timer functions in used split air conditioning give users effective control and help them save energy. The timer function is in the remote control. When activated, it turns the AC on or off depending on the set time. The function works for heating, cooling, and dehumidifying modes. Also, the sleep function gradually changes the room temperature for restful sleep. The feature works silently and saves energy. The temperature will remain at the user's chosen level until morning.

• Air Purification

  Users and manufacturers can improve indoor air quality with split ACs air purification feature. Sometimes, these systems have air purifiers, filters, and UV light. The air filtration system removes dust, allergens, and particles from the air. Users can replace or clean the filter regularly to improve its performance. Also, some units have a UV light in the indoor unit. It kills bacteria and viruses and makes the air healthier.

How to Choose Used Split Air Conditioners

Businesses buying used air conditioning units for sale need to consider several factors to ensure they find a reliable unit. Here are some of them.

• Type of Used Split Air Conditioner

  Split air conditioners come in two popular types: wall-mounted and ceiling； they also come in various shapes and sizes. The wall-mounted option is the most commonly installed kind. Mounting the unit on the wall is simple and straightforward. The outdoor component can also be mounted on the wall, but this is usually only possible with lighter models. If the model is heavier, it should be placed on the ground. In high ceilings, the ceiling-mounted split air conditioners work efficiently. Installing it on the ceiling is simple, but it requires more skilled labor. Ceiling cassette air conditioners can be as small a square block as 4×4 or as large as an 8×8 block. The larger models will be more difficult to install than the smaller ones.

• Energy Efficiency

  Business buyers need to check the energy efficiency ratio (EER) or the cooling efficiency ratio (CRF). These two factors determine how efficient an air conditioner is when it comes to energy consumption and its cooling capacity. The higher the EER or CRF, the more businesses will save on utility costs. A used unit with an EER of more than 11 and a CRF of more than 3 will be a good investment for businesses.

• Cooling Capacity

  The capacity of a used split air conditioner is often expressed in BTU, which means British Thermal Unit. Business buyers need to find out the BTU of different models first, and then they can estimate how many air conditioning units they need to buy for a specific space. The rule of thumb is that a 200 sq ft room requires a 5000 BTU air conditioner and a 10,000 BTU can cool a 400-450 sq ft room. A 12,000 BTU can work in a 450-550 sq ft room, and a 14,000 BTU air conditioner can cool 550-700 sq ft.

• Brands

  Renowned brands are more trustworthy than other brands. Popular brands invest more in research and development, providing customers with the latest air conditioning technologies. They also use better quality materials to manufacture air conditioning units. As a result, their air conditioners are more durable, reliable, and energy efficient. Because the brand is well established, businesses can find spare parts for their air conditioning units with ease. The air conditioner manufacturer will also offer excellent after-sales service.

• Temperature and Humidity

  The local climate and the split air conditioner used play a major role in determining the cooling capacity of the unit. Air conditioners with the ""desert"" label work better in hot and dry areas like the desert, where the temperature can reach 50º C. ""Tropical"" air conditioners are ideal for regions with high thermal and humid conditions like the tropics, models with ""European"" specifications are well-suited for low-temperature conditions up to 5ºC.
