Are there any air conditioners that don’t go in windows? We have long tall wide windows in our living room and dining room, so we can't put air conditioners in them :( It's so hot in our house. We ...

This article is an extension to “Mechanical Air Conditioners - Part I - Operating Principle”, and I will be talking about AC parts used in mechanical air conditioners.

Air conditioner parts that we put into a mechanical AC, should conform to the operating principle. Air conditioning parts for this type of equipment are divided into three categories. The,

# main and compulsory parts. This category is mandatory, otherwise, a mechanical air conditioner will not function at all

# the support parts, to ensure that the air conditioning equipment last long, and function effectively, and,

# the control parts, for improving efficiency of the equipment, and maintaining your comfort and bills - at optimum level

Main air conditioner parts

There are six parts in this category. Let’s explore them one by one,

# The compressor

Used for compressing refrigerant into high pressure gas into the condenser, and pulling in low pressure gas from the evaporator. The high pressure and low pressure is created by the compressor.

Common compressors used are piston type, scroll, and rotary compressors

# Condenser and evaporator

These are simple finned heat exchangers. These air conditioner parts, are formed using a serpentine shaped copper (or aluminium) tube, with aluminium fins.

Although the functions are different, the operating principle of these parts is the same. To encourage heat exchange between the refrigerant and air.

Condenser will function to liquefy high pressure refrigerant. Evaporator will function to completely boil low pressure refrigerant, into low pressure gas

# Expansion device

Common expansion devices are either capillary tube, OR thermostatic expansion valve. The function is to allow pressure build up from the compressor, and allow for refrigerant to expand into low pressure zone. This air conditioning part will also allow for boiling to start

# Tube

Tubes are air conditioner parts that has no moving parts. The main function is to direct refrigerant flow, and contain refrigerant within the AC. Common tube material is either copper, or aluminium

# Refrigerant

Air conditioners would not be able to cool, or heat anything without a refrigerant. Therefore, this part is essential. Refrigerant is used for absorbing (at evaporator), and expelling (at condenser) heat.

Common refrigerant type used in mechanical ACs are the HCFC (hydro-chloro-fluoro-carbon), and HFC (hydro-fluoro-carbon)

# Fans and blowers

Fans are placed at the condenser, and blowers are placed at the evaporator - to aid heat exchange. Blowers will also provide better air circulation within your house - and these supply with cool air to you, from the evaporator

Support air conditioning parts

These are conditioner parts provide the protection to the main parts, such that those will last long, and operate reliably. The list,

# Filter dryer receiver

Functions to filter small particles from the compressor, remove moisture within the refrigerant, and in some cases, acts as a receiver to supply full liquid column (without bubbles) to the expansion valve.

It is placed before the expansion valve, and after the compressor

# Filters

What more can I say. Air conditioner filters will prevent dust, and other particles from clogging up the evaporator. Of course, you’ll have to clean or replace it periodically

# Tube insulation

Is the simplest air conditioning part and utilised in refrigerant return line. This part will prevent icing, and condensation on the refrigerant return line.

Essentially, it will keep the refrigerant from evaporator cold, and allow for better cooling of compressor. Additionally, you’ll save on utility bills

# Muffler

As the sound deadening air conditioner part, placed at the outlet line of the compressor

# Casing

Well, to make sure you can transport main sections (condensing unit and evaporating unit) in simple packages, and used to protect sensitive and main air conditioner parts

Control AC parts

These air conditioner parts are more like the “essential accessories” for any mechanical air conditioner. Here we go,

# Thermostat and humidistat

The former AC part is used for controlling the temperature, and the latter for controlling the humidity. Thermostat is used in ALL ACs, but not humidistat. However, the inclusion of humidistat into the system in conjunction with thermostat is common in central ACs

# Contactor

Is and electrical component used to control the switching on, and off of compressors, fans, and blowers.

# Dampers

Dampers are used in central ACs, to control flow of air, such that you’ll get the right comfort from the air conditioning equipment. Dampers is almost vital in central ACs, as it is difficult to balance heat gain and loss requirement in each room - from a single condensing-evaporating central unit

Amcor PLM Series Portable Air Conditioners
At the very start of the summer, in the middle of a boiling hot day or sticky, humid night, you’re probably not going to mind too much what your air conditioner looks like, just so long as it keeps on oozing out those streams of cool, relaxing breeze.

Who cares if it’s a bulky, ugly box with an industrial type grill and a blocky frame that resembles a reject from an episode of Scrapheap Challenge? Just keep on breezing!

Well, that’s all true at first, but after a few days of enjoying the refreshing, energizing benefits of a portable air conditioner, you’ll probably start to think of it as a semi-permanent fixture in your home or office over the hot summer months.

And that’s when having a portable air conditioner that’s been designed with style and elegance will really make a difference and can even become a design enhancement to your home.

Introducing Amcor’s cutting edge PLM12KE and PLM15KE

Amcor’s PLM15KE and PLM12KE are the cornerstones of the US manufacturer’s ground breaking PLM Series – a range of portable air conditioners that were created with equal emphasis on form and function.

Just for the record, the key difference between the PLM12KE and PLM15KE is that the former runs at 12000 BTUs (British Thermal Units) per hour and the latter at 15000. That’s not a huge gap but the extra power of the PLM15KE will be noticed in larger spaces (450-500 square feet).

The concept behind the PLM range was to bring the portable air conditioner into the digital age with a ‘Plasma’ style design that is undeniably sleek and stylish – especially so when compared with the aesthetics of the majority of mobile air con units on the market.

What are the main aspects of the design that give the PLM12KE and PLM15KE their stylish edge? Let’s break them down:

- Chic and sleek casing: the shell of the PLM series portable air conditioners is tall with smooth cut edges, a slight shimmer effect coating and a predominantly flat surface which creates a sense of simplicity and style

- Backlit digital display: The LCD readout on the PLM12KE and PLM 15KE air con units manages to be both an attractive centerpiece and very easy to use, thanks to its blue backlight and soft touch electronic controls

- Top mounted grill: The vent is positioned on the top so it’s not staring in your face, and it’s adjustable too to allow greater control over air flow

- Programmable remote: The functions of PLM12KE and PLM15KE can all be operated via a thin and unobtrusive remote control which also features an easy to read LCD display.

Amcor portable air conditioners: more than just a pretty face

We reckon you’ll agree that looks wise you’ll be hard pressed to find a more perfect portable air conditioner for a modern home.

However, they do say it’s what’s inside that counts so it’s definitely worth covering the main technical aspects of the PLM12KE and PLM15KE to demonstrate that Amcor really has combined style with substance in the PLM Series.

Here’s a run-through of 10 great reasons to buy an Amcor PLM range portable air conditioner: 1. More efficient cooling thanks to its patented Evaporative Booster
2. Three speeds to choose from (two fans plus one turbo option)
3. 3M Filtrete filter that removes dust, pollen and animal hair
4. Activated carbon filter that helps to remove odour from the room
5. Washable air filter that collects dust particles and prevents build-up of bacteria
6. Built-in castors for easy moving around the room
7. Full thermostat control
8. Programmable 24 hour timer
9. Exhaust hose extendible to up to 5 feet long
10. Moisture removal capacity of around 80 pints per day
