The Art & Science of Heating, Refrigeration, Air Conditioning & Ventilation
Heating, refrigeration, and air conditioning deal with the thermodynamic properties of fluids, which can be in gaseous or liquid form.
Their control has an important bearing on our comfort, our environment, and on the production of our products. The engineering, design, and application of equipment and systems that produce and maintain these often critical conditions are an important part of the total package of our design services.
Our design and application specialists have a total of over 120 years of experience in the HVAC industry, specializing in applications with challenging requirements. We have many years of experience serving a wide variety of companies in the New England area. Since 1950, Denron Hall has had a registered Professional Engineer on staff, providing engineering oversight of critical projects. As the need for mechanical drawings carrying an Engineer’s stamp becomes increasingly commonplace, we are able to fulfill this requirement with in-house personnel.
Offices and Manufacturing Facilities
We have vast experience in designing and installing HVAC systems for both office complexes and manufacturing facilities. Each of these demands different engineering and design practices.
Office Buildings
The variety of functions and design criteria applicable to office buildings today has allowed the use of almost every type of air conditioning system. In addition to the typical office building floor plan, there are often retail stores, restaurants, data processing centers, and other types of occupancy as part of the office building complex. Each has its own special HVAC requirements to consider. A typical office building has a people load whose productivity and comfort must be assured by systems that provide proper control of:
- Temperature
- Humidity
- Ventilation
- Indoor air quality
Organizations must ensure that the design of HVAC systems are flexible enough to accommodate floor plan alterations as changes in tenant requirements occur during the building’s life.
Manufacturing Facilities
Manufacturing facilities usually require specific environmental conditions depending on the process and product being manufactured. More than ever before, close control of temperature and humidity is required for a production process. Products used in the electronics, telecommunication, and biochemical fields must be manufactured in specially designed clean rooms. Manufacturers must remove contaminants released as a result of a manufacturing process through proper ventilation and exhaust.
