How Air Temperature Affects Your Sleep
Experts agree that the temperature of your sleeping area determines how well you sleep. When you to go to sleep, your body tries to achieve a specific temperature that is neither too hot nor cold, but generally lower than your normal temperature. This drop in temperature induces sleep that is why it is much easier for you to fall asleep in a cold room. This is also the reason you are more likely to wake up if the room gets uncomfortably hot or cold.

What’s the Best Temperature for Sleeping?
Recommending a specific range is difficult, because people differ. While a typical recommendation is to keep the room between 18 - 22°C (65 and 72°F) it is advisable to set the temperature to one that is comfortable for you.

Temperature and office work performance
A human body performs best in the temperature range of 19 to 24°C. The rate at which a person performs at work depends on the temperature comfort level of the body. If the temperature is too high or too low, body does not perform to the maximum efficiency. So, the role of the air conditioner is to regulate the temperature of your environment, so that you can have a conducive environment to work effectively.

Humidity plays a critical role in making an environment comfortable or uncomfortable. Air conditioners help control humidity by blowing cool air, thus providing air circulation and also reducing the temperature of the room through distribution of cool air. So, key things to watch out for an air conditioner, is air flow, capacity and Dehumidification rate (Moisture removal rate)

 2. Types of Air Conditioners

• Window Air Conditioners
• Split Air Conditioners
• Package Air Conditioners

Window Air Conditioners
This type of ACs are designed to be fitted into window sills, otherwise a wall opening is required. Window units are preferably installed in walls open to air to ensure drain issues and hot air issues are not encountered. The advantages are the low initial cost and ease of installation. The concerns of this type of air conditioners are high noise levels, safety as the unit is easily accessible to burglars. They are the least aesthetically pleasing of all ACs.

Split Air Conditioners
Split unit ACs come in two parts: the indoor unit and the outdoor unit. The two units are connected by a copper pipe and a pipe is connected to the indoor unit to remove drain water from the unit. The Outdoor units house the condensers which can be made of either copper or aluminium. Copper condensers are better as they have better heat efficiency, have a low cost of repair and are easily repairable but the initial costs are higher; aluminium condensers on the other hand have low cost but are extremely difficult to repair. The indoor units are fixed to the walls inside(ideal height is 2 metres from the ground). 

The Advantages of Split Air Conditioners include:
• Better air distribution and uniform room temperature
• Better aesthetics
• Multiple design options are available for indoor units, which can be selected based on interior décor
• Quiet and efficient operation

Package Air Conditioners
Package air conditioners are large size split air conditioners with bigger fans for better air delivery in large areas and high ceiling areas. They also come in indoor and outdoor units. The key difference is Package air conditioner indoor units sit on the floor in contrast to split which are hung.

3. Features

What are the key features I should look out when buying an Air conditioners

There are many key features built into modern air conditioning units, the list below should help you decide what’s important to you;

Cooling Capacity: The cooling capacity of an air conditioner describes how powerful the unit is. If your unit doesn't have enough cooling capacity, it won't have the power to adequately cool your space; this should certainly be considered before making a purchase. An air conditioner's cooling capacity is usually measured in BTU (British Thermal Units) per hour, or Horsepower. Please refer to load chart guide for selection required for your home or office.

Power input and Energy Efficiency: Power input is the amount of power (wattage) required to run an air conditioner. Efficiency of an air conditioner is normally measured as Energy Efficiency Ratio (EER), which is the ratio of the cooling output, to the power input. This means the higher the EER, the more efficient the air conditioner is. Temperature settings, thermostat type and cooling speed also affect the operation time and Energy consumption of the units.

Low Voltage Operation – This feature basically allows your air conditioning unit to operate efficiently even under low voltage conditions and gives a good cooling performance. Haier Thermocool’s low voltage operation design is specifically designed for the Nigerian power conditions.

In Built Voltage Protection – Appliances such as air-conditioning units are particularly vulnerable to damage caused by low voltage ‘brownouts’. With in built voltage protection, your equipment is protected against all power fluctuations: over-voltage as well as low voltage, spikes, surges, power back surges and power fluctuations.

Noise Level: All air conditioners will make some sort of noise, however, newer models on the market have been engineered to be quieter than older units. Window units have highest noise level. Noise level for the split is low, and is dependent on the unit’s design. Haier Thermocool range of air conditioners have the reduced noise level feature.

Auto Restart – The Auto restart function enables the air conditioner to restart and resume the set operating conditions in the event of a power supply shutdown without the use of the hand control.

Healthy Intelligent Air - With this cutting-edge technology, the air flow of your air conditioning unit can be easily adjusted not to blow directly to the human body, which in turn provides healthier airflow and uniform cooling for your space.

Healthy Dehumidification -This function reduces the humidity in the air to create a healthy environment for you and your loved ones

Washable pre-filters - Washable pre-filters and odour-eating carbon filters help reduce smells. The washable filters remove dust, dirt or hair that can damage the air conditioner. These filters are easy to remove and can be washed clean.

 4. Size/capacity 

What sized air conditioner do I need?
The amount of cooling an air conditioning unit is capable of is measured in British Thermal Units (BTU). The higher the BTU rating the larger the volume of air a machine can cool. All AC units carry a BTU rating.
Usually a cooling requirement is a very complex process and many factors affect the capacity required e.g. number of windows, direction of the room, number of people, heat generating equipment inside the room etc.

The graph to the left illustrates an easy way to help you select the air conditioning unit that’s right for you. Work out the size of the space you’re aiming to cool in m2, then use the graph to work out the horse power (HP) of the air conditioner than would most effectively cool your space.

 7.  3 steps to selecting the perfect air conditioner for you.

Below is a 3 step process to help in choosing the right Air conditioner for you!

1. Calculate Capacity: This is determined by the size of the room, calculate the    capacity needed for your room by applying the simple rule of thumb discussed using the graph above(4. Size/capacity).

2. Type of Air conditioners: This largely depends on the area to be cooled and     available space for installation. Usually split units can be installed for majority of  applications, as the outdoor units can be kept at a distance of up to 10 meters       from indoor units; however it is always advised to keep the distance shortest to     avoid efficiency loss. For the large areas and double height areas with high occupancy, Package unit is advised.

3. Features: These are the benefits intended by the user for the use of the Air conditioners, these include, indoor design options matching your interior, specific       technology e.g. turbo cooling, inverter type, health benefit, dehumidification and filter type, Ease of maintaining copper or aluminium condenser.
