Cool without the dampness! Two-Stage Evaporative Air Conditioners are the top choice. They’re simply the best of the best! It makes both cold air and cold water, using both to make the unit work at its best. No waste.Also, they cool indoor air without making it damp! The main advantage of the second stage is that it maintains peak efficiency, even when outdoor humidity is moderate.That’s because the second stage cools the water from the first coils before it goes back into the tank. It ensures the unit works perfectly, giving you fantastic temperatures!

Pros and Cons of One-Stage & Two-Stage evaporative cooling

Today, homeowners have numerous choices, yet many are unaware of the benefits of one-stage or two-stage evaporative cooling over their existing systems. Let’s simplify it as if we were discussing in your home. Our mission? Providing you with all the essential information to make the best decision for your home.

– Direct evaporative cooling

Direct evaporative cooling, also known as one-stage or wet bulb cooling, is direct because water touches the air directly. In this process, water evaporates right into the air that needs cooling. It’s widely used globally, especially in dry areas.

  • Benefits

One big advantage is the price. Single-stage evaporative air coolers are the most affordable to buy and install. If you’re tight on cash, this is likely your top pick. And don’t fret, it’ll still cool your home well if sized and installed right

  • Drawbacks

Direct evaporative cooling has its cons. Using it for cooling can make indoor areas feel damp and sticky due to added moisture. Also, it’s not as efficient in places with high outdoor humidity because it can’t evaporate water effectively when the air is already saturated.

– Indirect/direct evaporative cooling

Two-stage evaporative cooling, also called indirect/direct cooling, combines indirect and direct methods to cool the air. First, the indirect step involves using condenser coils indoors to pre-cool the air and remove humidity by turning it into water vapor.

In the second step of direct adiabatic cooling, the air gets even cooler thanks to the wet evaporative media. This two-step process significantly lowers the air temperature, reducing its ability to hold much humidity

  • Benefits

When humidity is high, you can get effective cooling by using a two-stage evaporative cooling system. This semi-hybrid system is the best choice for handling high humidity. It keeps places like production halls cool all year round, even in humid months, while still saving lots of energy.

  • Drawbacks

While the initial cost may seem substantial in contrast to traditional evaporative air cooler options, these systems offer exceptional long-term value and cost-effectiveness.

Vankool Evaporative Air Conditioner

Humidity affects the temperature of the room, or more specifically how it feels to us. When the Vankool evaporative air conditioner runs, it removes humidity from the air, making the system more efficient.

Similarly, the Vankool 2-stage system runs for longer periods, circulating air in your home more frequently. This removes more particles from the air and introduces more fresh air, benefiting your overall air quality.

VEAC™ stands for Vankool Evaporative Air Conditioner, the world’s first eco-friendly air conditioning system for commercial use with proprietary technology.Unlike a standalone evaporative cooling system or a traditional air conditioner, VEAC™ uses an innovative system that combines evaporative cooling with a refrigeration cycle to achieve optimal cooling at about 25℃.

– Environmentally friendly alternative, with 90% lower energy consumption

– Cools up to 7 ℃ deeper than single-step systems

– Brings up to 70% less moisture in the supplied air than direct systems

– Up to 30% less water consumption than single-step systems

Selecting the optimal evaporative cooling unit

There’s no ‘best’ option, but there are options that might be more suitable for different homes and homeowners. By familiarizing yourself with the various types, you can narrow down which one is the right fit for you. Here are a couple more considerations that could help you in your decision-making process.

  1. How aboutthe average relative humidity of your home ?If you’re in an extremely hot or humid climate, you might find better heat relief with a Vankool evaporative air conditioning unit. Traditional air coolers are designed for areas with hot, dry weathe
  2. Can you leave a window or door open?Evaporative units work best in rooms with an open door or window to let fresh air circulate. If you can’t keep them open because of noise, insects, or security reasons, an evaporative unit might not be the right choice for you.
  3. What is your budget ? Although you might envision having a fully equipped air conditioning system at home, it’s crucial to consider your budget before deciding. Two-stage evaporative air conditioners cost more upfront than single-stage air coolers and consume more electricity in the long run.
  4. What size is your space?Before ordering an evaporative unit, assess your space to determine the best size for your needs. If you choose a unit that’s too small, it’ll struggle to cool the area efficiently, wasting energy and leaving you uncomfortable. Consider the unit’s CFM (Cubic Feet per Minute) rating, which indicates how much fresh air it cycles through your room each minute. Calculate your CFM by multiplying the square footage you need to cool by the ceiling height, then dividing by two.

Whether you select an air cooler or a two-stage evaporative air conditioner, this investment can create a more comfortable, enjoyable, and healthy atmosphere in your home during the summer. With temperatures steadily climbing year after year, rely on this guide to pick a cooling unit that will keep your family cool and content for many summers to come.
