Air Conditioning Solutions for Park View Flat 2

Be Cool recently worked with Brompton Cross Construction to provide Park View Flat 2 with an advanced air conditioning solution. In order to provide the best possible comfort and visual coherence throughout the apartment, a combination of Mitsubishi and Daikin systems was used in this project. Here, we examine the layout, functionality, and design of these systems, demonstrating how VRF (Variable Refrigerant Flow) technology satisfies contemporary home cooling needs.

Project Overview

We built a Daikin system with two indoor units specifically for the living room and a Mitsubishi VRF system with six indoor and one outdoor unit for Park View Flat 2. Each system was selected to optimise energy efficiency and comfort in various apartment zones, enabling customised climate management.

Proposal

Innovative Installation Solutions

In order to preserve the apartment’s sophisticated layout while optimising its available area, we employed multiple creative approaches:

  • Concealed Air Conditioning Units: We hid the air conditioning units behind joinery cupboards for the Daikin systems in the large living spaces. This approach preserved the aesthetic appeal of the rooms and ensured that all equipment was discreetly integrated into the design.
  • Ceiling Void Installation: For both systems, we concealed all units within ceiling voids. The supply air was introduced via ceiling coving, eliminating the need for visible grills or equipment. This technique maintained the ceiling height in the main rooms and contributed to a clean, uninterrupted design.

Overcoming Common Challenges within London

Space Efficiency: Making sure the air conditioning system did not sacrifice design or space was a significant problem. We effectively solved this problem by placing the units in ceiling voids and joinery cupboards, which preserved the apartment’s elegant appearance while maximising comfort.

Planning Permission: Another major obstacle was getting planning authorisation for outdoor condensing units. Permission was first denied. In order to get around this, we built a special plant room and added sufficient air circulation, maintaining the system’s peak performance without the need for outside units. This technique preserved the effectiveness of the system while adhering to local laws.

The Perks of a Compact VRF System

At Park View Flat 2, both systems operate as a component of a small VRF system. This arrangement saves space and energy as it enables several interior units to link to a small number of outside units. Temperature controls for individual rooms are possible, providing flexibility and lowering energy usage.

Performance and Efficiency

The Mitsubishi system at Park View Flat 2 was designed for top efficiency. The total cooling capacity stands at 15.62 kW, with no additional pipe run required, ensuring minimal energy loss. The system uses R32 refrigerant, which is environmentally friendly and ensures efficient cooling with a reduced carbon footprint.

The system meets both EN 378-1:2016 standards for toxicity and IEC 60335-2-40 Ed 6.0 standards for flammability, ensuring safety and compliance with European regulations.

In a nutshell

Collaborating with Brompton Cross Construction on the Park View Flat 2 project has been a success. By integrating Mitsubishi VRF technology with Daikin’s reliable systems and addressing common challenges with innovative solutions, we provided a tailor-made air conditioning system that balances comfort, efficiency, and design.

At Be Cool, we specialise in delivering high-performance air conditioning solutions that meet modern needs while being energy-efficient and environmentally conscious.

How Often Should You Change Your AC Filter? The Science Behind Air Filter Maintenance

Your air conditioner’s filter might seem like a simple component, but it plays a crucial role in maintaining indoor air quality and ensuring your AC system’s optimal performance. Understanding when and how to change your filter can prevent costly repairs and improve your home’s air quality significantly.

air conditioning unit filter change

The Critical Role of AC Filters in Your HVAC System

Your air conditioning filter serves as the first line of defense against airborne particles. As air circulates through your HVAC system, the filter captures dust, pollen, pet dander, and other microscopic particles. Without proper filtration, these contaminants can accumulate inside your AC unit, leading to reduced efficiency and potential system damage that may require professional AC repair.

How Often Should You Really Change Your AC Filter?

The frequency of filter changes depends on several key factors:

Standard Households (1-2 people, no pets)

Change your filter every 90 days. This timeline assumes average air quality and regular AC usage. However, during peak cooling seasons, consider checking your filter monthly for visible dirt accumulation.

Homes with Pets

If you have one pet, change your filter every 60 days. For multiple pets or pets that shed heavily, monthly changes are recommended. Pet hair and dander can quickly clog filters, forcing your system to work harder.

Families with Allergies or Respiratory Conditions

Replace filters every 30-45 days. More frequent changes help maintain better indoor air quality, which is crucial for family members with respiratory sensitivities.

Homes in High-Pollution Areas

For houses near construction sites or in areas with high pollution levels, check filters every 2-3 weeks and replace them monthly or as needed.

How to Replace Your Air Conditioner’s Filter

The Science Behind Filter Maintenance

Understanding how filters work helps explain why regular maintenance is crucial. Your AC filter uses a combination of mechanical and electrostatic filtration:

Mechanical Filtration

The filter material creates a maze-like structure that captures particles through:

  • Interception: Particles stick to filter fibers
  • Impaction: Larger particles collide with fibers and become trapped
  • Diffusion: Smallest particles move erratically and eventually stick to fibers

Impact on AC Performance

A clogged filter can reduce airflow by up to 50%, causing:

  • Increased energy consumption
  • Reduced cooling efficiency
  • Extra strain on AC components
  • Higher utility bills

This is why our regular maintenance service includes thorough filter inspection and replacement as needed.

Signs Your Filter Needs Immediate Replacement

Don’t wait for scheduled replacement if you notice:

  1. Visible dust accumulation on the filter surface
  2. Increased energy bills
  3. Longer cooling cycles
  4. Visible dust around air vents
  5. More frequent allergy symptoms

Choosing the Right Filter Type

MERV (Minimum Efficiency Reporting Value) ratings indicate filtration effectiveness:

MERV 1-4

Basic filtration suitable for minimal air quality needs. Changes needed every 30-60 days.

MERV 5-8

Medium filtration good for most households. Replace every 60-90 days.

MERV 9-12

Superior filtration recommended for homes with pets or allergy sufferers. Change every 45-60 days.

MERV 13-16

Hospital-grade filtration requiring professional AC installation assessment to ensure system compatibility.

Professional vs. DIY Filter Changes

While changing filters is typically a DIY task, having a professional examine your system during filter changes can prevent potential issues. Our maintenance specialists can:

  • Assess filter compatibility with your system
  • Check for proper filter installation
  • Identify potential system issues early
  • Recommend optimal filter change schedules

Long-term Benefits of Regular Filter Maintenance

Consistent filter maintenance provides numerous benefits:

  1. Extended AC system lifespan
  2. Reduced energy costs
  3. Improved indoor air quality
  4. Prevention of major repairs
  5. Better cooling performance

Regular filter maintenance is essential for optimal AC performance and indoor air quality. While general guidelines suggest changes every 60-90 days, your specific situation might require more frequent replacements. When in doubt, schedule a professional maintenance check to establish the best filter maintenance schedule for your system.

AC Filter Change FAQs

Check the label on your current filter or refer to your AC system's manual for the correct dimensions.

No. Disposable filters are designed for one-time use and cleaning them can damage the material, reducing effectiveness.

HEPA filters are ideal for homes with allergies or respiratory concerns. However, ensure your system is compatible before switching.

Some systems have filters in both the air handler and return vents. Replace all filters simultaneously for optimal performance.

Yes. If you're uncomfortable replacing the filter or want a full system check, hiring a technician is a good option.

Filters have arrows indicating airflow direction. Ensure the arrow faces the direction air flows into the unit.
