3 5hp Evi Enhanced Vapor Injection Scroll Compressor Is Special Design

3 5hp Evi Enhanced Vapor Injection Scroll Compressor Is Special Design The dtc exv valve is approved for all refrigerants in this product range. a dtc exv valve must also be used for zf**k5e applications with r 407a, r 407c, r 407f, r 448a and r 449a with vapor injection via a special t fitting adapter. further details and part. The solenoid valve selection considers a minimum pressure drop of 0.05 bar and a maximum pressure drop of around 0.5 bar across the compressor operating envelope. the selection of the solenoid valves in the single injection line can be carried out according to table 5. compressor. recommended kv (m3 h).

New Generation Enhanced Vapor Injection Evi Scroll Compressor Ice For a design point capacity of 4kw a reciprocating compressor will deliver typically 6 to 7kw when the condensing temperature falls to 20°c, as shown in figure 4. for a constant load this represents 50 75% over capacity. by contrast a vi scroll having equal design point capacity would deliver 4.5kw or just 12.5% over capacity. Enhanced vapor injection (evi) compressor electronics technology 40°f to 0°f * zfd**k5 enhanced vapor injection (evi) 10% to 100% digital modulation compressor electronics technology 40°f to 0°f * *evap temperature can vary per refrigerant hp models plant 1.0 – 6 hp zo21k5, 34 45 58k3, 88 104kc zod34 58k3, 104kc n. ireland 1.0 – 3.5 hp. • the zfi*kqe models that are optimized for vapor injection with the use of a subcooler. this boosts the refrigeration system's cooling capacity and efficiency. high efficiency all year round • the unique copeland compliant scroll design patented by emerson operates under continuous scroll flank contact, maintained by centrifugal force. Copeland scroll evi compressors are equipped with an injection connection for economizer operation. economizing is accomplished by utilizing a subcooling circuit. this mode of operation increases the refrigeration capacity and in turn the efficiency of the system. see ae4 1327 for more information.
