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

Heater -the device that heats water or supplies warmth to a room.

heating - a device or system for supplying heat, esp central heating, to a building

ventilation a.The replacement of stale or noxious air with fresh air. b.The mechanical system or equipment used to circulate air or to replace stale air with fresh air.

Air conditioning - a system or process for controlling the temperature and sometimes the humidity and purity of the air in a house.

Exercise 2. Ask questions to the given answers:

1) Question: ______________________________________________?

Answer: The three central functions of heating, ventilating, and air-conditioning are interrelated.

2) Question: ______________________________________________?

Answer:Central heating is often used in cool climates to heat houses and public buildings.

3) Question: ______________________________________________?

Answer: A heater is an object that emits heat or causes another body to achieve a higher temperature.
