Abstract

Increasingly air conditioners are used in commercial and residential buildings. It is known that the utilization of these devices causes water condensation yielding a drip that is, usually, connected to the sewage system, being discarded or even neglected, causing pathological manifestations in buildings and their surroundings. Furthermore, the water scarcity is also an increasingly recurrent problem due to dry seasons and, therefore, all possible reuse of water resources must be carried out. The aim of this work is to analyze the amount of the water condensed from an air conditioner located in the Campus de Cachoeira do Sul of the Universidade Federal de Santa Maria and verify possible relations with air humidity and temperature. For this purpose, tests were carried out for one hour of operation in a device located in a University classroom, in which were measured parameters such as air temperatures and humidity, external and internal to the classroom, and the volume of water generated at the end of the test. It was checked that the amount of water generated is significant, with an average of 1662 ml, being the highest amount generated on a one-hour period with high temperature and humidity and the smallest amount on a day with the same parameters significantly lower.

Ethical Guidelines for Journal Publication

The Ciência e Natura journal is committed to ensuring ethics in publication and quality of articles. 

Conformance to standards of ethical behavior is therefore expected of all parties involved: Authors, Editors, Reviewers, and the Publisher.

In particular, 

Authors: Authors should present an objective discussion of the significance of research work as well as sufficient detail and references to permit others to replicate the experiments. Fraudulent or knowingly inaccurate statements constitute unethical behavior and are unacceptable. Review Articles should also be objective, comprehensive, and accurate accounts of the state of the art. The Authors should ensure that their work is entirely original works, and if the work and/or words of others have been used, this has been appropriately acknowledged. Plagiarism in all its forms constitutes unethical publishing behavior and is unacceptable. Submitting the same manuscript to more than one journal concurrently constitutes unethical publishing behavior and is unacceptable. Authors should not submit articles describing essentially the same research to more than one journal. The corresponding Author should ensure that there is a full consensus of all Co-authors in approving the final version of the paper and its submission for publication.

Editors: Editors should evaluate manuscripts exclusively on the basis of their academic merit. An Editor must not use unpublished information in the editor's own research without the express written consent of the Author. Editors should take reasonable responsive measures when ethical complaints have been presented concerning a submitted manuscript or published paper.

Reviewers: Any manuscripts received for review must be treated as confidential documents. Privileged information or ideas obtained through peer review must be kept confidential and not used for personal advantage. Reviewers should be conducted objectively, and observations should be formulated clearly with supporting arguments, so that Authors can use them for improving the paper. Any selected Reviewer who feels unqualified to review the research reported in a manuscript or knows that its prompt review will be impossible should notify the Editor and excuse himself from the review process. Reviewers should not consider manuscripts in which they have conflicts of interest resulting from competitive, collaborative, or other relationships or connections with any of the authors, companies, or institutions connected to the papers.
