I. Reading Exercises:

 

Exercise 1. Read and memorize using a dictionary:

technology of indoor and vehicular environmental comfort; skyscrapers and in marine environments; hand in hand; acceptable indoor air quality; room air distribution.; chilled water; boost the temperature; duct work; fiberglass ducts; pollen particles; baseboard heaters;PEX tubing; hypocausts;formaldehyde; volatile; adverse health effects; lethal; fatigue, nausea, and vomiting;cardiovascular and neurobehavioral effects; atherosclerosis; the hardening of arteries; heart attack; vigilance; ppm- parts per million;

Exercise 2. Answer the questions:

1) What is HVAC system design?

2) What is heating, ventilating, and air conditioning based on?

3) What is a heater?

4) Whom is the invention of central heating often credited to?

 

Exercise 3. Match the left part with the right:

1. HVAC system design is a subdiscipline of mechanical engineering, a) to the field's abbreviation as HVAC&R or HVACR.  
2. Refrigeration is sometimes added b) based on the principles of thermodynamics, fluid mechanics, and heat transfer.  
3. The invention of the components of HVAC systems went hand-in-hand c) incomplete combustion and the emission of carbon monoxide, nitrogen oxides, formaldehyde, volatile organic compounds, and other combustion byproducts.  
4. The use of furnaces, space heaters and boilers as means of indoor heating may result in d) with the industrial revolution.

 

Exercise 4. Open brackets choosing the write words:

There are many (different/various) types of heating systems. Central heating is often(used/ utilized) in cool climates to heat houses and public buildings. Such a system (contains/ includes) a boiler, furnace, or heat pump to warm water, steam, or air in a central (location/ position) such as a furnace room in a home or a mechanical room in a (large/small) building.

II. Speaking Exercises:

Exercise 1. Learn the definitions: heater;heating; ventilation; air conditioning

III. Writing exercises:

Exercise 1. Complete the sentences with the suggested words: important; such as; are; humidity

HVAC is 1 in the design of medium to large industrial and office buildings such as skyscrapers and in marine environments 2 aquariums, where safe and healthy building conditions 3 regulated with respect to temperature and 4, using fresh air from outdoors.

 

Exercise 2. Compose a story on one of the topics (up to 100 words):

 

Innovative technologies in power engineering

A heater is an object that emits heat

Heating systems”

 

Lesson 15

 

 

 

Read the text: Innovative technologies in power engineering: ventilation (Continued)

Ventilation is the process of changing or replacing air in any space to control temperature or remove any combination of moisture, odors, smoke, heat, dust, airborne bacteria, or carbon dioxide, and to replenish oxygen. Ventilation includes both the exchange of air with the outside as well as circulation of air within the building. It is one of the most important factors for maintaining acceptable indoor air quality in buildings. Methods for ventilating a building may be divided into mechanical/forced and natural types.
