1. ­­­­­­Abstract
The main purposes of this experiment are to allow students to get familiarized with air conditioning system and also to obtain experimental data so that the state point can be plotted on a psychrometric chart. The apparatus used in this experiment are SOLTEQ air-conditioning module (Model:HE166-02) which is designed to work with the Base Condensing Unit. The major part of the evaluation procedure is carried out with the aid of psychrometric chart. Thus, the heating power, cooling power and steam enthalpy can be calculated through the experiment.

2. Introduction & Theory
2.1 Air Conditioning
Air conditioning is a system or process for maintaining a living space or industrial facility at the desired temperature and humidity of the air. The SOLTEQ Air-Conditioning Module can be easily couple to the base condensing unit to form a complete refrigeration circuit. This unit involves several components connected by ducting for the air flow. The unit of air conditioning generally contains a blower, heater, cooler, humidifier and de-humidifier. Before the air going into the ducting, it is entering a variable speed centrifugal fan. Steam can be injected when the air entering the fan due to humidify the air. After that, the air passed over externally finned electric elements (pre-heating). The warmed air passed into a stabilizing section with humidity or temperature sensor before flow through the evaporator where it may cool and deposit some of its moisture content as liquid. The cool and drier airs passing over re-heating element after enter another stabilizing section. The re-heater air is flow back to the atmosphere after the condition has been determined.

There are four basic process carried out in air conditioning system:
Heating

    Air conditioners and heat pump systems are used by most people in the world today. They are used to cool in the summer time and to heat in the winter time. These machines are bought and used when most people do not even understand the principle on which they work. The machines are expected do what they are designed to do, and when they cease to do this, they can be costly to repair. Air conditioners and heat pumps are similar in appearance and operation, but while using the same components they can perform completely different tasks. Knowing the difference between the two and the principle in which they perform their tasks will enable each person to make an informed decision when the time comes to repair or replace a piece of equipment.…

    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…

    There are two basic approaches to cooling the air in an enclosure: refrigeration and evaporation. In the refrigeration cycle, a fluid is compressed so that its temperature rises and is circulated through pipes over which air or water is forced, thus removing heat. The compressed, cooled refrigerant is then expanded through a nozzle, so that its temperature drops sharply before it absorbs heat in an exchanger from the air in the enclosure. The refrigerant with the heat absorbed is then compressed and its heat removed in the exhaust heat exchanger. This process need not include phase change. When a substance evaporates, it absorbs a great deal of heat from the environment, called the latent heat. In large industrial systems, the…

    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.…

    The air conditioner relys on the compressor to pump refrigerant through the system in order to provide cold air. When the compressor fails, the choices are to replace it or install a new air conditioning installation. Unless the system is fairly new, or still under warranty, replacement of the system is often the best…

    A chiller is a machine that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle. A vapor-compression water chiller comprises the 4 major components of the vapor-compression refrigeration cycle (compressor, evaporator, condenser, and some form of metering device). These machines can implement a variety of refrigerants. Adsorption chillers use municipal water as the refrigerant and benign silica gel as the desiccant. Absorption chillers utilize water as the refrigerant and rely on the strong affinity between the water and a lithium bromide solution to achieve a refrigeration effect. Most often, pure water is chilled, but this water may also contain a percentage of glycol and/or corrosion inhibitors; other fluids such as thin oils can be chilled as well.…

    Are you tired of being hot? Well, air conditioners are your friend. In 1902, the first modern electrical air condition was invented by Willis Haviland Carrier. The reason for it was to solve some problems a printer was having with papers in the summer (“Title” 1). Air conditioners and refrigerators worked the same way. Instead of cooling just the small, insulated space inside of a refrigerator, an air conditioner cools a room, whole house, and/or entire business. Air conditioners use chemicals that easily convert gas to a liquid and back again.…

    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…
