Industrial Refrigeration (all solved)

As defined in chapter 1 of this text the primary purpose of refrigeration system is correct answers To maintain a temperature Operators must keep refrigeration systems operating safely and efficiently. Which of the following best describes the areas of required knowledge for this to be possible. correct answers Basic physical principles, Interpreparation of information from temperature and pressure gauges. Basic operating principles. Mechanical refrigeration is a series of steps that correct answers moves heat energy from the space or object to an area where It can do no harm. Heat energy always flows correct answers From an object at a higher temperature to an object at a lower temperature sensible heat correct answers Is heat energy that causes a change in temperature but does not cause a change of state Latent heat correct answers Is heat energy that causes a change of state but does not cause a change in temperature Which of the answers below is an example of heat transfer by convection correct answers Warm air moving over an object How does the refrigeration technician/operator know what the conditions are within the refrigeration system correct answers By using his knowledge of system basic operating principles to evaluate temperature and pressure readings How was cooling accomplished by mechanical refrigeration system correct answers By removing heat energy from one object or area Which of the following is used to measure the quality of heat energy correct answers British thermal units BTUs or calories. Which of the following are used in heat calculations correct answers Mass, latent heat, temperature, specific heat. Latent heat of vaporization correct answers Is the heat energy required to cause a liquid to become a vapor Pressure is A measure of correct answers The relationship of a force being applied over a given area The relationship between temperature difference in heat flow is correct answers The greater the temperature difference the more rapid the heat flows
