MV3402	MARINE REFRIGERATION AND AIR CONDITIONING	LTPC

3204

OBJECTIVES: To impart the knowledge of students in

• Reciprocating compressors.
• Basic refrigeration and air conditioning.
• Marine refrigerating plants.
• LMTD and NTU Methods.

UNIT I	RECIPROCATING COMPRESSORS

Ideal cycle for compressors work transfer in a single stage compressor – mass flow – volume flow – free air delivery – effect of clearance and volumetric efficiency in single stage compressors. Multi stage compression neglecting clearance volume. Condition for minimum work input and perfect inter cooling. Tandem in line arrangements in compressors. air motors.

UNIT II	BASIC REFRIGERATION AND AIR CONDITIONING

Reversed Carnot cycle – vapour compression cycle – refrigerating effect – co-efficient of performance – cooling capacity – refrigerants used in marine practice and their justification - rating of refrigeration plant – methods for improving C.O.P. – use of vapour tables – applied problems.

UNIT III	MARINE REFRIGERATING PLANTS

Typical marine refrigerating plants with multiple compression and evaporator system – heat pump cycles – refrigeration in liquefied gas carriers – applied problems.

UNIT IV	MARINE AIR CONDITIONING

Principles of air conditioning – Psychrometric properties of air – comfort conditions – control of humidity – airflow and air conditioning capacity – calculation for ships plants.

UNIT V	BASIC DESIGN OF HEAT EXCHANGERS

Introduction - types - LMTD and NTU method - double-pipe, shell and tube type, condenser and evaporator – problems

TOTAL: 75 PERIODS
