R32 Refrigerant: The Environmentally Smarter Choice for Internal Air Conditioning

Learn how Cool You utilises R32 refrigerant in its air conditioning. As the world shifts toward greener and more energy-efficient technologies, the air conditioning industry is following suit. One major advancement in this direction is the adoption of R32 refrigerant—a next-generation solution that’s transforming how we cool our homes and workplaces.

At Cool You, we’re proud to lead the way in sustainability and innovation. That’s why all our fully internal water-cooled air conditioning systems use R32 refrigerant, helping London homeowners enjoy powerful cooling without compromising environmental responsibility.

In this article, we’ll explain what R32 refrigerant is, how it compares to older refrigerants, and why its use in Cool You’s internal systems offers both environmental and practical benefits for our clients.

What is R32 Refrigerant?

R32 (also known by its chemical name difluoromethane) is a hydrofluorocarbon (HFC) refrigerant used in air conditioning systems. It belongs to a new class of refrigerants developed to replace older, more harmful gases like R410A, R407C, and R22, which have been widely used for decades but are now being phased out due to their high Global Warming Potential (GWP).

R32 has become the preferred refrigerant in residential and commercial air conditioning systems because it strikes a balance between efficiency, safety, and environmental performance.

The Environmental Benefits of R32

1. Lower Global Warming Potential (GWP)

GWP is a measure of how much heat a greenhouse gas traps in the atmosphere compared to carbon dioxide. The higher the GWP, the more harmful the substance is in terms of contributing to global warming.

• R410A, a commonly used refrigerant, has a GWP of 2,088.
• R32, in contrast, has a GWP of just 675—that’s approximately 68% lower.

This significant reduction makes R32 a far better choice for the environment. When an air conditioning system using R32 reaches the end of its life or needs servicing, it leaves a much smaller environmental footprint than systems running on older refrigerants.

2. Zero Ozone Depletion Potential (ODP)

Unlike some older refrigerants like R22, which damage the ozone layer, R32 has zero ozone depletion potential. This makes it safe for the atmosphere, contributing to global efforts to protect the ozone layer.

3. Higher Energy Efficiency

R32 systems are more energy-efficient than those using R410A, especially under partial load conditions. That means they consume less electricity, which in turn reduces indirect emissions from power generation.

This makes R32 systems not only greener but also more cost-effective to run—something every homeowner can appreciate.

Why Cool You Uses R32 in Our Internal Air Conditioning Systems

At Cool You, we specialise in fully internal water-cooled air conditioning systems—a game-changing solution designed for apartments and homes across London where traditional external condensers are not allowed.

By using R32 refrigerant in our systems, we deliver all the benefits of modern air conditioning while staying at the forefront of environmental responsibility.

Here’s how our approach makes a difference:

1. Advanced DC Inverter Technology for Ultimate Efficiency

Our systems use high-efficiency DC inverter technology, which constantly adjusts the compressor speed to match the exact cooling demand of the room. Instead of turning on and off like older systems, inverter-driven units operate more smoothly and efficiently, maintaining the desired temperature with greater precision and significantly less energy use.

This intelligent modulation results in:

• Faster cooling and temperature stability
• Quieter operation
• Lower electricity consumption
• Longer system lifespan due to reduced wear and tear

By combining R32 refrigerant with inverter technology, Cool You systems are not only sustainable—they’re among the most energy-efficient air conditioning solutions available for London apartments.

2. Unique 3000-Stage Water Flow Control Valve

Our commitment to precision extends beyond the refrigerant loop. Every Cool You system is equipped with a sophisticated 3000-stage water control valve, which continuously adjusts the water flow through the system to maintain optimal thermal performance.

Unlike basic systems that use a simple open/close valve (which only turns on or off based on rough thresholds), our multi-stage valve:

• Dynamically fine-tunes the water flow
• Responds to real-time cooling demands
• Optimises system performance minute by minute
• Reduces energy consumption by avoiding unnecessary water usage

This advanced technology ensures that our systems work in perfect harmony with building cooling supplies, using only the water flow necessary to maintain the desired indoor temperature—no more, no less. It’s a level of efficiency and control that sets Cool You apart from many other internal AC providers.

3. Fully Internal and Fully Compliant

Because our systems don’t require an external condenser, there’s no disruption to your property’s exterior—no planning permission, no scaffolding, and no compromising your home’s appearance.

Furthermore, by utilising R32, our systems comply with or exceed current environmental regulations, including those outlined in the EU F-Gas Regulation, which aims to phase down the use of high-GWP refrigerants across Europe.

That means your Cool You system is future-proof and compliant with tightening environmental standards.

4. Efficiency That Cuts Energy Use and Costs

Thanks to the combined benefits of R32 refrigerant, DC inverter technology, and precision water flow control, our systems achieve outstanding levels of energy efficiency. This translates to:

• Lower running costs
• Reduced carbon footprint
• Enhanced comfort with less noise and more consistent temperature control

Many of our clients are surprised by how quiet, effective, and economical our systems are, especially compared to legacy or externally mounted units.

Why the Switch to R32 Matters Now

The move to R32 isn’t just about technical innovation—it’s part of a broader movement toward sustainable living.
Regulators across Europe and the UK are phasing out older refrigerants. Manufacturers and installers must stay ahead of the curve, as consumers are increasingly seeking environmentally sound choices.

At Cool You, we’re proud to be part of this positive change. By incorporating R32 into all our internal air conditioning systems, we’re offering clients a solution that’s:

• Technologically advanced
• Environmentally responsible
• Perfectly suited to modern London homes
