Read the text and answer the question:
Why is the humidity control so important?
"Psychrometric" literally means "pertaining to the measurement of cold", but in modern usage it refers to the state of the atmosphere with reference to moisture. The earth's atmospere — the air we breathe and the air in most refrigerated spaces — is mainly a mixture of dry air and water vapor. Of course in special cases other gases or vapors might also be present. But generally speaking, in refrigeration applications the atmosphere is considered a mixture of dry air and water vapor.
Although the relative amount of water vapor in the atmosphere is very small (about 0.08 per cent by weight at 0°F saturated only 1.56 per cent at 70 F saturated), variations in this amount as well as changes in temperature are very significant and important in air conditioning. Relative to human comfort, there is much truth in the common expression, "It's not the heat, it's the humidity". Humidity means the amount of water vapor within a given space.
In many instances humidity controls is very important. Poor register is often noticed in colored printing, particularly in the Sunday comics; adjacent colors overlap or do not meet. A change in atmospheric humidity between the printing of the different colors probably was the cause, since paper shrinks and stretches as the humidity changes. In a meat cooler, too low a humidity can cause shrinkage, or drying out, which means a loss of product and less income to the owner. On the other hand, too high a humidity promotes a growth of mold and possible spoilage of the product. Therefore it should be evident that a study of psychromentry, including the properties of air-vapor mixtures and their measurement and control, is important in air conditioning.

FROZEN PRODUCTS AND DEEP-FROZEN PRODUCTS.
In a frozen product most of the water is transformed into ice and is separated from the other constituents. For this, it undergoes a special freezing process that allows it to retain its character and quality and keeps to a minimum possible physical, biochemical and microbiochemical deteriorations during freezing and preservation.
The term "deep-frozen product" is often used. This term and its equivalent ("quick-frozen product") mean that the set of rules which are listed below have been observed by the manufacturer and by the various professionals who help to distribute these products:
— the product shall be from the start in the best possible condition;
— depending on the nature of the product, specific treatments shall be done before freezing (cutting up, cleaning, etc.);
— freezing shall be done in an industrial freezer in such a way that the zone of maximum crystallization (-1° to -5°C) is rapidly crossed, and the temperature everywhere in the product is brought to -18°C or below;
— the product shall be protected by an airtight package suitable for the product and the conditions of use;
— the temperature of the product shall be kept at -18°C or below during storage, transport and marketing.
There is no scientific criterion for distinguishing a frozen product from a deep-frozen one. But for a frozen product it is possible not to follow all the conditions above. In particular, the product could, depending on its nature, be stored at -18°C, as long as the temperature on no account surpasses - 10°C; it could go without an airtight package; it could be intended for industrial sale, etc.
I. Translate the following word-combinations. Point out the basic words:
low-temperature frozen product; frozen-packed product; liquid freezer; deep freezer; commercial freezer; frozen package; airtight package.
II. Find in the text sentences with the verb "shall". Define its function.

AT A CONFERENCE
Before any scientific Conference an Organizing Committee sends to all the concerned establishments the "First Announcement" or "First Circular". It states general information about the Conference and contains a Preliminary Application Form which gives information on participation. Those who want to attend the Conference should complete the Application Form and mail it without delay.
The Second Announcement contains information as to the terms of the Conference, commissions, participation and registration, pre-, mid- and post-Conference tours, scientific visits, living accommodations,enrollment fees, Ladies' program and everything for the participants to make maximum use of the occasion.
Any Conference is directed by a Chairman. It is duty of the promoters of the meeting to elect the Chairman. This is done either by a show of hands or by a paper vote.
The success of the Conference depends on the capabilities of the Chairman. His address should be much shorter than any of the speeches that follow.
When the Conference is open, the first matter for the Chairman is to read the agenda. Then the Chairman reads the correspondence requiring consideration, including letters of apology for absence. Anyone who wants to take the floor should ask the Chairman beforehand or by simply raising his hand after the Chairman opens the discussion.
It is very rare that a report is actually read even during scientific Conferences. As a rule papers presented at Plenary sessions are distributed to the delegates in a printed form.
During the discussions when speaking members stand and must preface their words with the
proper formula: "Mr. Chairman, Ladies and Gentlemen... / Dear Colleagues... / Dear Friends... To address the Chairman is obligatory in English-speaking practice of public meetings.
When a lady takes a chair, she should be addressed as Madam Chairman.
The agenda is a list of the subjects which the Conference is called to consider. The agenda must determine the order in which matters are discussed by the members. The time for main reports, general discussions, concluding speeches, elections and final resolutions should be fixed whitin the agenda.
At each Conference a Secretary sits on the platform close to the Chairman and makes notes from which the minutes must be written up.
Minutes as a rule show only main ideas of the speakers and the decisions recorded at the meeting.
Any scientific Conference may decide to adopt some resolution or appeals to finish its work. Very often a Drafting Commitee is elected to present a draft resolution. A final resolution is adopted when all amendments are discussed.
The final duty of the Chairman is to call upon a member to make a vote of thanks.
After the speaker's words of gratitude to the Chair, the contributors, the sponsors, the audience, the services, and to local administration for organization of the Conference and for hospitality, the Chairman declares the Conference closed.
Notes:to take the floor — взяти слово, виступити
amendments — поправки
a vote of thanks — заключне слово з виразом вдячності
hospitality — гостинність
