The Importance of a Good Ventilation System
DD Cooling provides ventilation systems designed to supply fresh air into your building whilst extracting stale air. With added heat recovery technology, your new ventilation system can recover heating or cooling energy to help warm/cool incoming fresh air.
Good indoor air quality is vital for any commercial premises, to ensure it functions effectively and efficiently. Ventilation installation allows ‘clean’ air to be intentionally filtered into space and stale air to be removed. Effective ventilation design is needed to provide oxygen for metabolism and to dilute metabolic pollutants (carbon dioxide and odour). It allows for maintaining good indoor air quality, by diluting and removing other pollutants emitted within a space. A good ventilation system is a major contributor to the health and comfort of building occupants, with the added bonus that it can be additionally used for cooling and heating.
Natural ventilation proves less effective, as the demand for improved energy efficiency results in increasingly airtight buildings, and so drives the need for mechanical ventilation.
Poor indoor air quality can lead to a loss in productivity and low morale, it can be attributed to many problems inside a building such as pollutants known to cause damaging health issues. Plus poor air quality can lead to excess humidity, which causes dampness, rot and moult. This in turn can prove costly to any business and damage the internal environment.
Installation of Ventilation Systems
We provide a complete range of ventilation solutions, including the design and installation of fresh air systems, heat recovery ventilation (HRV) systems, ventilation upgrades and retrofits, as well as ongoing maintenance and servicing to ensure optimal performance and air quality.

Expert Ducting Services
DD Cooling is an approved delivery partner for EcoDuct. Find out how we can help you with our range of insulated ducting solutions offering superior thermal efficiency, enhanced air quality, and faster installation all while reducing the need for floor space and ceiling clearance.

EcoDuct Delivery Partner
We are pleased to announce that DD Cooling is now an approved EcoDuct Delivery Partner. For insulated ducting projects, we are now able to offer both Spiralite® and Koolduct® products to suit the specific application.
Traditionally, HVAC ductwork is constructed from galvanised sheet steel, which is installed first and then insulated separately as a second operation. Our new partnership allows DD Cooling to provide our clients throughout Lancashire and the North West with more lightweight, cost-effective, space and energy-saving solutions. Both Spiralite® and Kingspan KoolDuct® systems have numerous advantages over traditional metal ducting with mineral fibre insulation.
Installed in a single–fix and available in a variety of colours and finishes, allowing your project to benefit from open-to-view aesthetics. Our new product ranges offer the highest levels of thermal efficiency, clean air distribution, and speed of installation; and allow reduced floor space and headroom.
Advanced, lightweight pre-insulated ductwork systems
This innovative, rectangular HVAC ductwork system is installed in a single fix, eliminating many of the disadvantages associated with galvanised sheet steel, mineral fibre duct board and pre– insulated rigid polyisocyanurate (PIR) ductwork systems.
Designed for mechanical ventilation, heating and air-conditioning systems, The Kingspan KoolDuct System is suitable for both new build and refurbishment projects in the residential, commercial, public, light industrial and leisure sectors. Moreover, it is especially suitable for use in nonferrous applications such as MRI scanning units in hospitals, and on other high specification projects where non-fibrous insulants may be preferred.

Energy efficiency
In line with Government targets, changes to building regulations have been introduced to improve energy efficiency and reduce carbon emissions.
Part L of the Building Regulations calls for buildings to be more airtight and energy efficient. Maintaining good indoor air quality through effective ventilation is vital and MVHR & AHU’s are perfectly placed to achieve this. Part L gives guidance on the maximum amount of electricity that an air distribution system should use.
Part F of the Building Regulations focuses on ventilation systems and indoor air quality in both domestic and commercial buildings.
Air Conditioning for a Gym
A gym can get hot and stuffy, especially during busy times or high-intensity workouts. Providing air conditioning and ventilation helps extract stale air and supply fresh air, ensuring the environment is more comfortable and pleasant for members. This improves their overall experience and encourages repeat visits.
What is a heat recovery system?
Basically, it is an energy recovery ventilation system that uses an air-to-air head exchanger that recovers normally wasted heat, while at the same time supplying fresh highly filtered air, improving the indoor environment. Heat recovery systems work independently from your heating system, but due to it recovering heat that is usually lost it can have great savings on energy bills.

Mechanical ventilation products
DD Cooling provides a range of mechanical ventilation products such as Mechanical Ventilation with Heat Recovery units (MVHR), Air Handling Units (AHUs) and AHU control interfaces. All of these systems have been designed to deliver a fresh air supply to a building, whilst simultaneously extracting stale air in the most efficient manner.
A MVHR system virtually eliminates condensation and mould within a building, by constantly ventilating the space. An MVHR system is extremely efficient and can recover up to 90% of heat lost through extraction and transferral to incoming air.
DD Cooling offer industry-leading Mitsubishi Electric Lossnay Heat Recovery systems, ensuring your building maintains a healthy and comfortable environment. The Mitsubishi Lossnay system utilises paper cores within both its MVHR and AHU systems to provide excellent ventilation alongside a heating and/or cooling system.
The benefit of the system includes:
- Clean, fresh air
- Improved air quality and comfort
- Increased climate control
- Energy-efficient heat recovery
- Reduced energy bills
