are the substances that can harm living organisms, buildings and/or equipment and subject to establishing of maximum permissible concentration.  
 
HEAT EXCHANGER
укр. Теплообмінник; рус. Теплообменник
is a piece of equipment or appliance built for efficient heat transfer between two or more heat transfer mediums or between heat transfer medium and a solid body surface.   
 
HEAT RECOVERY
укр. Теплоутилізація; рус. Теплоутилизация
is a process of heat or cold utilization providing their using for air heating or cooling.
 
HEAT RECOVERY UNIT
укр. Теплоутилізатор; рус. Теплоутилизатор
is aheat exchanger transferring heat or cold (sometimes moisture) from one airflow to another directly or through intermediate heat transfer medium.
 
HEATING
укр. Опалення; рус. Отопление
is process of forced room warming for compensation of heat losses providing normative indoor temperature during heating season.
 
HEATING CAPACITY
укр. Продуктивність по теплу; рус. Продуктивность по теплу
characterizes the amount of heat produced per time unit.
 
HUMIDIFIER
укр. Зволожувач; рус. Увлажнитель
is a device of spray or evaporative type used for evaporative cooling and air humidification in adiabatic mode (evaporative humidifiers) or by means of water cross spraying through nozzles.

IMBALANCE
укр. Дисбаланс; рус. Дисбаланас
is the difference between supply and exhaust airflow rates in mechanical draft HVAC and R systems.
 
INDOOR CLIMATE
укр. Мікроклімат приміщення; рус. Микроклимат помещения
includes indoor environment conditions, which affect people heat transfer with ambience by convection, conduction, radiant heat and moisture evaporation. Mentioned conditions are determined by the combination of temperature, relative humidity and airflow speed, temperature of ambient surface and radiant heat (infrared) intensity.
 
INFILTRATION (OF AIR)
укр. Інфільтрація (повітря); рус. Инфильтрация (воздуха)
is the unintentional introduction of outside air into a building, typically through cracks in the couplings, loose air ducts, windows, doors etc.
 
INITIAL AERODYNAMIC RESISTANCE
укр. Опір аеродинамічний початковий; рус. Сопротивление аєродинамическое начальное
is a resistance of the new filter before commissioning.
 
INITIAL DUST CONCENTRATION CORE
укр. Ядро початкових концентрацій пилу; рус. Ядро начальных концентраций пыли
is a segment where dust concentration is equal to the dust concentration at the filter outlet.
 
INITIAL DUST CONTENT OF AIR
укр. Початкова запиленість повітря; рус. Начальная запыленность воздуха
is initial dust concentration by mass of particles entering the filter.
 
INLET TOTAL PRESSURE
укр. Запас повного тиску на виході; рус. Запас полного давления на выходе
is a total pressure required for surmounting of external aerodynamic losses occurred in the ductwork connected to the AHU.
 
INSPECTION HOLE
укр. Лючок; рус. Лючок
is a small lockable opening in the air duct or equipment for air parameters measurement (pressure, temperature etc.), for the further control and adjustment of the ductwork.
 

INSTALLED POWER

укр. Установна потужність; рус. Установочная мощность
