Specifics of Maintaining Supply Air Parameters in Surgery Rooms
A. A. Borodkin, Candidate of Engineering, Technical Director at LLC Engineering Bareau VINDEKO
Keywords: clean room, air distribution, laminar ceiling, HEPA filter, constant air flowrate regulator
Surgery rooms are considered especially clean rooms. For air distribution they usually use laminar ceilings, sometimes with 14th class HEPA filters. In the course of operation the filter resistance can increase five-fold. After four-fold drop of pressure at the filter the air flow through the filter can become twice as little. This is unacceptable. CAV regulators (constant air volume regulators) are being used today to solve this problem. They compensate for an increase in the filter resistance by reducing their own resistance. This article tries to understand whether CAV-regulators are really this indispensable.

Keywords: quasimembrane, ventilation, air flow, air flow regulation

One of the main methods for reduction of energy costs of operation of multizone ventilation and air conditioning systems is regulation of their capacity based on changes in load in serviced rooms. Use of adaptive systems with quantitative regulation becomes efficient only when the regulating algorithm is based on the information on the air flow size (air flowrate) continuously controlled in the process of the systems operation in different modes.

This methods includes measurement and regulation of not only the air flowrate in individual zones using terminal units of VAV, FPB, etc. types, but also the total air quantity coming into the system. This allows for development of an optimal system operation algorithm and improvement of the energy efficiency of its operation.

This article is dedicated to a narrower question: optimization of the methods of measurement of the total air flowrate coming into the system (or removed from it).

Energy Efficient Ventilation of Hot Shops in Public Catering Enterprises

A. V. Livchak, Candidate of Engineering, Halton Vice-President
Keywords: air flowrate, aerodynamic characteristics, CFD models, adaptive ventilation, balancing valve

Restaurants are considered public buildings with the highest specific energy consumption per unit of area. And the main energy consumers are kitchen equipment and HVAC system, their total contribution is up to 80% of the total energy consumed by restaurants. The path to development of an energy efficient design of a restaurant always starts from a heat source – from the food production technology and kitchen equipment. Low efficiency devices of high power additionally heat up the production area and require high air exchange rate, i.e. increase the energy consumption for HVAC. More efficient kitchen equipment, such as induction cookers and combination steam ovens, spends less energy on heat production and does not heat up the production area as much, thus reducing the energy consumption for kitchen ventilation and cooling.

The next step towards an energy efficient design is HVAC system optimization – the subject of this article. Air flowrate through kitchen exhaust is the most important element of an HVAC design, since it dictates the amount of energy consumed by hot shop ventilation system. And really, the higher air flowrate through local exhausts leads to higher consumption by motors of exhaust and supply fans, and the energy required for cooling or heating of air supplied to production area to compensate for the exhaust.
