74mm Discharge Hermetic Reciprocating Compressor Zeotropic MTZ64HM4CVE

Maneurop Refrigeration Hermetic Reciprocating Compressor MTZ64HM4CVE

Product description:

At low ambient temperatures, the condensing temperature and condensing pressure in air cooled condensers will decrease. This low pressure may be insufficient to supply enough liquid refrigerant to the evaporator. As a result the evaporator temperature will strongly decrease with the risk of frosting.
At compressor start-up, the compressor can pull a deep vacuum and it can be switched off by the low pressure protection. Depending on the low pressure switch setting and delay timer, short cycling can occur. To avoid
these problems, several solutions are possible, based on reducing condenser capacity:
• Indoor location of condensers
• Liquid flooding of condensers (note: this
solution requires extra refrigerant charge, which can introduce other problems. A nonreturn valve in the discharge line is required and special care should be taken when designing the discharge line.)
• Reduce air flow to condensers.
