The characteristic called "temperature glide" (glide) refers to the temperature range over which the refrigerant blend components evaporate or condense at a given pressure. A pure substance (such as water) at constant pressure will undergo a complete change food warmer rental of phase at constant temperature. Conversely, zeotropic refrigerant blend must proceed through a temperature range which varies with the aim of completing the phase change food warmer rental process. The name "temperature glide" or known as "glide" in English, refers to this range of temperature is not constant.
Similarly, if it is boiled inside a container, a zeotropic refrigerant, the temperature at which boiling starts is called Bubble Point Temperature (Bubble Point), and possibly the past few droplets will evaporate at the temperature of Point Dew (Dew Point). Yet both evaporation and condensation on the type evaporators and condensers "swamped" normally not exhibit any temperature glide because these are constantly fed with fresh coolant.
The special characteristics of refrigerant blends, such as the composition of liquid and vapor is different depending on the pressure and temperature. This causes concern regarding the changes in the composition of the refrigerant. The trasnferencia refrigerant and charge the same in refrigeration units by technicians and refrigerant leaks may also alter the composition. The change in composition could affect the performance of the refrigeration system to some extent. Inflammability food warmer rental
Some blends flammable refrigerants used in composition and others use a mixture of hydrocarbons only. Therefore, certain considerations should be taken up for implementation. Exist in some regions and countries are some limitations on the specific equipment for refrigerants such classes or even forbid. In DEVELOPED countries, blends based on HCFC replacement R12 are not widely food warmer rental used for the manufacture of new equipment or tasks retrofitting of existing units in part because of its ODP value (GWP), flammability and complications regarding service . In addition, the application retrofitting is not employed in developed food warmer rental countries mainly due to the availability of recycled CFC and the high cost involved in the retrofit. Pros and cons of blended refrigerants
* The composition blends that rely on HCFC refrigerants and are designed to replace the R12, can be mainly used with mineral oil and can provide an acceptable performance in the retrofit equipment. Cons:
* Due to the flammable food warmer rental and non-azeotropic characteristics, the method of service charge tends to be more complicated and technicians should be informed of the correct procedures.
* Leaks in heat exchangers and subsequent filling lead to a gradual change in the composition, resulting in a change in the performance and operational characteristics over time.
* Although the impact is short-term system performance and can the owner does not realize it is true that cross-contamination of the coolant / lubricant will reduce the energy efficiency of the unit and its performance, and shorten the operational life of system.
