Honeywell Distribution in Pakistan is in a critical period in a new era in the refrigeration sector. In this new decade of “fighting climate change,” high-fluoride. Greenhouse refrigerants are generally being phase out in favor of alternative refrigerants and solutions. Natural refrigerants have advantages and disadvantages. Solving these problems is part of the technical challenges we face today.
A wave of innovations in safe and easy-to-manage synthetic refrigerants for half a century. This has led to the development of the commercial freezing and air conditioning sector.
Cost of the Environmental Impact Honeywell Distribution in Pakistan
According to Honeywell Distribution in Pakistan each new synthetic refrigerant poses a new threat to the environment. CFCs for ozone depletion potential (ODP) and hydrofluorocarbons (PCA) for global warming. Trifluoracetic acid (TFA) is the only natural refrigerant that guarantees the planet’s long-term stability.
The term “natural refrigerant” is controversial. This is because all coolants are manufacture in industry. However, contrary to popular belief, natural coolants are naturally abundant substances. Therefore, leaving it in the atmosphere by man, intentionally or accidentally, does not affect the balance of the environment. For example, in this case, ammonia comes from the decomposition of organic matter. It is part of the natural nitrogen cycle.
Natural Refrigerant Environment Policy
This is an environmental policy mainly adopt by Pakistan. This led to the reduction of fluorine gas consumption and the development of natural refrigerants. Initially in the commercial freezing sector and later in the air conditioning sector.
The estimate decrease in GHG emissions of 44 MtCO2e from 2014 to 2019. Mainly due to progress in freezing (62%) due to acceptance of HFOs and natural refrigerants. It is expect to decrease in the future as well. The F Gas regulations introduce new measures in the air conditioning and mobile refrigeration systems sector.
Today, the main natural refrigerant use in the manufacture of ammonia is carbon dioxide. And hydrocarbons such as propane and isobutane. Other natural refrigerants such as polypropylene and ethane are not very useful
Ammonia
The Honeywell Distribution in Pakistan research on Ammonia or R717 is known as an excellent refrigerant with high refrigerant efficiency. However, due to its unique thermodynamic properties. Its high toxicity has the disadvantage of being slightly greater than its flammability for use in or near public places. Therefore, this is limit to large industrial systems. However, the latest low ammonia charging technology increases system safety by reducing the cost of the coolant require for cooling. For example, recent developments in micro-channel ammonia refrigeration, critical loading. And dry expansion have result in specific refrigerant values of up to 70 g/kW. This is the lowest level in the history of
cooling
Low-Charge Ammonia Technology
Another interesting application of low-charge ammonia technology. This was a huge success in Pakistan. This is a direct drive system that is different from the ammonia pump system. Advances in electronic refrigerant expansion control systems and the development of ammonia-compatible oils have solve two major problems. This new technology can reduce the ammonia content in the system to less than one-twentieth. Potential safety benefits satiate
Uses of R744, CO2 Gases
R744, CO2, or carbon dioxide has again been use in a variety of applications since the turn of the century. It is the best low temperature industrial refrigeration chiller and mainly use in Pakistan. Both as a phase changing liquid and as a cold phase coolant for a cascade circuit.
In commercial freezing systems, the CO2 transfer cycle is very popular in Asia. As one of the best solutions for large supermarkets.
However, due to the excellent low-temperature transport properties of CO. The performance of the transport circuits at ambient temperatures greater than 25 °C is poor. Which requires the development of advanced circuits to extend these systems to warmer Pak climates.
Among the various complexes that the industry has offered over the past decade. From mechanical sub-coolers to ejectors, parallel compression appears to be the most successful.
Commercial Freezing System
According to this principle, recent developments of screw compressors with medium pressure steam injection are also promising. The CO2 expansion of commercial freezing systems is associate with better and larger ingredient choices and lower prices. Over the next few years, we will see that the CO2 system will be expand. To a lower power range with a small power plant with an integrate gas cooler with an integrate unit.
The inefficiency of the conversion circuit at high evaporation temperatures hinders its use in the air conditioning sector. With the exception of the heat pump for instant hot water generation, the removable CO2 circuit provides excellent efficiency. This type of device has been sold and has been a great success for more than 10 years.
Hydrocarbon
According to Honeywell Distribution in Pakistan the properties of hydrocarbons. As refrigerants have been known since the beginning of mechanical freezing. But due to their high flammability, they were not the first choice.
Among the hydrocarbons, isobutane or R600a has become the standard for home freezing, producing millions of units annually. Charging just 100g of cooler is not dangerous for the kitchen.
On the other hand, propane or R290 is use in small air conditioners and small freezer units. Such as single block freezers and indoor freezer units. Another recent use of R290 in indirect pressure systems is the water loop system. Several pressure units and water pressure loop devices have recently been develop here. It has also been use successfully in commercial freezing systems such as small supermarkets and industrial kitchens.
Uses of R290 Gas
The use of R290 in medium-size freezer plants has led to the proliferation of indirect systems. In commercial freezer applications in medium-size supermarkets. R290’s excellent thermal performance compensates for defects in secondary circuits. The combination of functional equipment design, light practicality and location outside the building. Makes it a safe, versatile and reliable solution. The indirect control capabilities of the system have also increase. The demand for R290 freeze plants in Central and compare to direct CO2 expansion options.
Recent regulatory changes of Honeywell Distribution in Pakistan are opening exciting. Opportunities for using flammable refrigerants such as ammonia and propane in air conditioners. The previously prohibit low charge technology used for both coolants reduces risks to acceptable levels. Therefore, ammonia and propane can be use in refrigeration facilities and gas cooler heat pumps.
Final Words
Finally, Honeywell Distribution in Pakistan are at a defining moment. After a period of change and coexistence with fluoride refrigerants with moderate greenhouse effects. Natural refrigerants meet the diverse needs of the refrigeration and air conditioning sector. Today, there are many solutions with strengths and weaknesses in different applications. That need to establish a position in the market. HVAC Companies in Pakistan are development and improvement adjusts the potential of each person. It should also be remember that offloading the system plays an important role for both security and cost reasons.
