Analyzing the four major air conditioners and how to choose an efficient product ④

Use cost-effective air conditioners
In the previous article "Which is more economical? Continuous vs. intermittent operation of air conditioners", we compared the energy consumption when operating continuously and not in a well-insulated house. When operating continuously in a well-insulated house, it is possible to select the appropriate air conditioner based on calculations. As a result, the number of units and capacity can be significantly reduced, which saves on initial costs and heating and cooling costs. Furthermore, it also saves a lot on the cost of updating air conditioners every 13 years, which are said to last an average of 13 years.
Air conditioners can achieve the three functions of heating, cooling, and dehumidification at the lowest running costs. Considering that they combine three functions, the cost-effectiveness of air conditioners is overwhelmingly superior to other cooling, heating, and dehumidifying devices. How can we design a home that can make the most of this? And how can we select the appropriate air conditioner for that home?
It may seem very simple, but the reality is that there is no manual, and neither practitioners nor air conditioner manufacturers understand it well. The reality is that only a small number of very studious construction companies scattered throughout the country have a good grasp of the key points of this.
