Advanced Cold Storage Equipment Refrigeration Systems
What is Tafco Temp & Eco-Temp?
Tafco Temp is a unique concept in cold storage equipment that incorporates a number of features which enhance performance, provide energy savings over conventional cold storage systems, and increase reliability, thus saving you money. The heart of the Tafco Temp cold storage system is a design that eliminates the need for a refrigerant receiver. This is done by providing built-in storage capacity in the condensing coil circuit. This small change in the unit has opened the door for adding new features that are not possible with traditional refrigeration systems.
Increased Performance
Tafco Temp maintains traditional refrigerant storage capacity, while at the same time increasing the condenser capacity. It actually gives the same size condenser up to 20% more capability by providing a potential 50% increase in condenser surface. This feature reduces condensing temperature and pressure when compared to conventional systems, thus increasing compressor life. In addition, Tafco Temp increases compressor life by reducing the operating head pressure.
Increased Energy Savings
The increase in the condenser size and lower operating head pressure provide an initial energy savings of up to 10%. In order to take full advantage of the Tafco Temp large condenser, both a subcooling circuit and Tafco Saver floating head pressure features are incorporated to save even more energy.
The Tafco Saver feature provides up to 30% in additional energy savings during low ambient conditions. Further, it supplies subcooled liquid refrigerant to the expansion valve to maintain optimum valve performance. Thus, Tafco Temp can offer energy savings of up to 40% over conventional cold storage systems.
Fewer Refrigerants
Tafco Temp requires up to 20% fewer refrigerants to operate, while still maintaining continuous peak performance. This is accomplished several ways:
1) By dispensing with the conventional receiver, a minimum refrigerant charge is not required to maintain a liquid seal in the receiver.
2) It assures that only liquid refrigerant is entering into the subcooler section of the condenser because ambient air is flowing over the receiver section of the condenser coil.
3) It eliminates the useless overcharging of the system with refrigerant. In typical cold storage systems, the receiver’s outlet valve and piping will create bubbles in the sightglass due to the pressure drops they create. In turn, this results in the addition of extra refrigerant by the installer in an attempt to clear the sightglass. By eliminating the receiver and its piping components, the clearing of the sightglass occurs much faster. Tafco Temp critically positions sightglass signals when the ideal charge has been attained, thus saving refrigerant. With today’s refrigerant costs, Tafco Temp makes even more sense.
