The Split-Air Type Conditioner
The Split-type air conditioner
Some rooms do not have external windows or walls. Difficulties arouse in creating sufficient air flow in the rooms, which can lead to discomfort for residents in terms of temperature and humidity.
The split-type air conditioner can be used in these situations.
Introduction:
A split air conditioning simply means that the condensor (or sometimes referred to as the “outdoor unit”) is separated from the “indoor unit”, thus the term “split”.
The split air conditioning has at least one unit that sits inside your room. The compressor sits outside of the room, sometimes on the ground or on brackets hung to the wall. Some models come with multiple indoor units that will use one single compressor, this is known as the multi-split air conditioning system.
In a split air conditioning system, the amount of cold air entering the room can he controlled by a thermostat or it can be regulated by an infra-red remote control, like a TV remote. One room or one area of a building can maintain a different temperature from another room or area in the same building. Split air conditionings are the perfect solution for spot cooling - for example, in residential houses where only certain rooms are required to be cooled at certain times like a living room during the day and a bedroom at night but also in large structures like retail stores and supermarkets, where spot cooling is essential in areas which can be either too hot or too cold.

The Split type air conditioning units have become very popular and have dominated the market in recent years. They are available with the indoor unit mounted on the wall, into the ceiling space, under the ceiling or on the floor.(Alexander, 2008)

A Split system may be used when the home has a forced warm-air furnace with a blower and a duct work.

    The refrigeration system can be defined as a closed system in which the process of absorbing and rejecting heat is performed by flowing a refrigerant in a vapor compression cycle. In its simplest form, the refrigeration system consists of five components: the compressor, condenser, evaporator, expansion device, and interconnecting piping.…

    REFRIGERATION SYSTEM COMPONENTS There are five basic components of a refrigeration system, these are: Evaporator Compressor Condenser Expansion Valve Refrigerant; to conduct the heat from the product In order for the refrigeration cycle to operate successfully each component must be present within the refrigeration system. The Evaporator The purpose of the evaporator is to remove unwanted heat from the product, via the liquid refrigerant. The liquid refrigerant contained within the evaporator is boiling at a low-pressure. The level of this pressure is determined by two factors: The rate at which the heat is absorbed from the product to the liquid refrigerant in the evaporator The rate at which the low-pressure vapour is removed from the evaporator by the compressor To enable the transfer of heat, the temperature of the liquid refrigerant must be lower than the temperature of the product being cooled. Once transferred, the liquid refrigerant is drawn from the evaporator by the compressor via the suction line. When leaving the evaporator coil the liquid refrigerant is in vapour form. The Compressor The purpose of the compressor is to draw the low-temperature, low-pressure vapour from the evaporator via the suction line. Once drawn, the vapour is compressed. When vapour is compressed it rises in temperature. Therefore, the compressor transforms the vapour from a low-temperature vapour to a high-temperature vapour, in turn increasing the pressure. The vapour is then…

    Over the past few years, Air Conditioning witnessed immense new changes that are changing the way we see ACs from an addition to necessary. The new trend in construction is green. Greener buildings greener technologies, everything tends to lower the carbon foot print of a building/complex. Mechanical equipments are no different especially since they represent more than 50% of the electrical consumption of a project (residential buildings, Villas, Hotels, Schools etc…) Over the course of this subject we learned the importance of water and air chillers – compared to normal split units – as they tend to give better return on investment as the project grows older and larger. Nevertheless, having numerous AHUs and FCUs in one complex only meant high energy bills, which brought the necessity to join different systems in one. This brings us to the topic of new type of chillers, the dedicated heat recovery chiller (DHRC). Resort/convention hotels, hospitals and nursing homes as well as athletic facilities located in warm climates, demand heat and cool at the same time. Unlike old systems where boilers used to work in parallel to the chiller system to respond to the demand for hot water, DHCR systems include a heat exchanger with allows to heat the water exiting it to the designated water temperature to perform various tasks like: Reheat coils Building heating (low temperature < 130° F) Domestic water heating (washing and showers) Swimming pool heating Laundry water heating Snow melting Process heating Kitchen water for dish washing and clean up…

    AC Load: The duty of the air conditioning system is to compensate for other thermal loads so that the cabin temperature remains within the acceptable comfort range. In cold weather conditions, positive AC load (heating) is required for the cabin. Inversely, in warm conditions, negative AC load (cooling) is needed for maintaining the comfort conditions. The actual load created by the AC system depends on the system parameters and working conditions. In this work, it is assumed that an AC (or heat pump) cycle is providing the thermal load calculated by…
