VRF systems operate on the direct expansion (DX) principle meaning that heat is transferred to or from the space directly by circulating refrigerant to evaporators located near or within the conditioned space.

DX stands for direct expansion cooling. In DX cooling equipment, a refrigerant coil is placed directly in the supply air stream. As the refrigerant evaporates and expands, it removes energy, lowering the temperature of the supply air stream.

The immediate and most noteworthy difference between these two systems is that the DX units cool air using refrigerant and CHW units cool the air utilizing chilled water. A DX unit uses refrigerant-based cooling and cools indoor air using a condensed refrigerant liquid.

The Different Types of Air Conditioning Systems

• Window Air Conditioners.
• Portable Air Conditioners.
• Wall Hung Split or Multi Head Split Air Conditioners.
• Ducted Air Conditioning.
• Air Conditioners For a Diverse Range of Situations.

5 Different Types of Air Conditioners

• Central Air Conditioners. Central AC is by far the most common type of air conditioner found in homes today.
• Ductless, Mini-Split Air Conditioners.
• Portable Air Conditioners.
• Hybrid Air Conditioners.
• Evaporative Air Conditioners.

Packaged air-conditioning systems are central air, often installed as part of a dual heating and air-conditioning system (HVAC). If your residence already has forced air heating (and therefore ductwork), packaged or central air conditioning will be the most efficient and (relatively) least expensive option.

26 SEER / 16.5 EER The Lennox XC25, at the head of the premium Signature Series, is the most efficient split system central air conditioner with a 26 SEER rating. Some mini split ACs (at comparable cost) and geothermal heat pumps (at much higher cost) are more efficient, but no standard central AC.

The Top 5 Air Conditioning Manufacturers in the World

• Hitachi. Due to the fact that Hitachi is currently the foremost air conditioning company (amongst other products), it only makes sense that it clinches the first spot on this list.
• LG. Securing the second spot on our list is LG Corporation.
• Daikin.
• Samsung.
• Voltas.

Panasonic It is touted as the number one AC brand in Japan.

Top 3 Most Expensive ACs are as follows:

• Godrej GSC 18 FG 6 SOG Split AC: 1.5 Ton capacity: For space around 150 sq.
• Hitachi RSD318HBEAZ1 1.5 Ton 3 Star BEE Rating 2018 Split AC: Dust Filter, 3 Star Rating, Remote Control, 1.5 ton Capacity, Copper Condenser Coil.

Chances are pretty good a new Daikin ductless system is going to cost less than a new Mitsubishi ductless system. In fact, several times a year our Mitsubishi/Trane units cost less than our Daikin/Goodman units. In other words, get the quote to compare – you may get a more reliable unit for less money.

Mitsubishi Electric air conditioners are generally durable. All their models are made out of India and are imported. One reason for that is that their market presence is less in India. Being an imported brand, their products are quite expensive, which makes it hard for them to penetrate the market.

Mitsubishi Heavy Industries continues to blow away the competition, rating best in Canstar Blue’s air conditioner review for the second year in a row. It earned five-stars for reliability, functionality & features, noise, ease of use and overall satisfaction.
