Перевод

Lecturer: Here we have what’s called a packaged air conditioning unit. It’s called that because it contains all its parts in one unit. Now I’ve removed the front of the cabinet so you can see inside. Notice that it is located on an outside wall so that fresh air can be drawn in here. O.K. Can you all see? The air then passes through these aluminum air filters. Student: What is the function of the air filters? Lecturer: Umm…Well, it filters the air removing the dust so… Student: So that’s why it’s dirty. Lecturer: Err…Yes, but you are able to remove the filters for cleaning. In fact this one should be cleaned as soon as possible. Err…yes; the air passes through the evaporator and… Student: What does that do? Lecturer: Well, That serves the function of cooling the air. You see, a gas is circulated through the condenser here. That’s a cooling device which turns the gas into liquid. It then passes through a valve into the evaporator here where… Student: Where the liquid evaporates. Lecturer: Err…Yes, that’s right. The liquid expands into a gas and absorbs heat from the evaporator which… Student: Absorbs heat from the air. Lecturer: Yeah-Yeah. Now keep quite will you and don’t touch that. Student: What is the evaporator made up of? Lecturer: Oh. The evaporator consists of cooling coils made of cooper with aluminum fins They are designed to absorb the maximum amount of heat. The cool clean air is now forced into the room through the adjustable louver by… Student: A fan. Lecturer: Yes, the fan is over here. I’ll switch it on now so you can see how it works. Stand back. Now look. I told you not to touch that… (BANG)
