Introduction
Malaysia agricultural countries in the state estimated to hold an country of aˆ‹aˆ‹6.6 Million hectares and rich with agribusiness harvest. Agribusiness is besides a beginning of income for people in Malaysia. Labor force in Malaysia was estimation increased from twelvemonth to another twelvemonth. They involve in nutrient sub-sector and industrial trade goods. Agriculture Industrial trade goods sector is more to plantation activities such as palm oil, gum elastic, chocolate, wood and lumber, Piper nigrum and other plantation activities. This sector supplies the natural stuff to nutrient industry or consecutive supply to users.
Then, other agribusiness sector is nutrient sub-sector. Food sub-sectors more to harvest, farm animal and piscaries activities. Almost harvest, farm animal and piscaries yield from farming demand to keep the freshness of the merchandise. The quality of agribusiness merchandise was decided by National Agriculture Policy ( NAP ) . Agriculture sector is alternate sector to fabricating sector during 1997 Asiatic Financial Crisis.
Hence, agribusiness merchandise demand to more productive, efficient and competitively to increase production agricultural production including new beginning of growing with new find.Air conditioning and refrigerant system in agribusiness sector help a batch in this sector. Refrigerant and air conditioning system usage to keep the freshness and quality of the agribusiness merchandise in order to bring forth and provide to Malaysian. Hence, it really of import to hold refrigerant and air conditioning system in agribusiness sector to increase the life span of the agribusiness merchandise and to bring forth high quality agricultural merchandise in Malaysia.
Air conditioning and refrigerant system used to chill and keep the temperature of merchandise and edifice environment. This system increase the efficiency to chilling and dehumidification comparison to the traditional manner. Therefore, air conditioning and refrigerating system give benefit in agribusiness sector and can be used widely. The standard utilizing of the air conditioning and refrigerant system for agricultural sector have difference due to the agribusiness harvest and any agriculture merchandise.
The suited air conditioning and refrigerating system applied in agribusiness industry.
Refrigerating and Air conditioning System
Traditional Refrigerating and Air conditioning system may easy to trail out by new engineerings. The traditional system may non efficient and durable to keep chilling and refrigerant system.Since 19th century, the basic refrigerating and air conditioning system non changes excessively much. Refrigerating and air conditioning work by compacting fluid and so let it to spread out. The compressive fluid was heat up the fluid, therefore heating its milieus.Then, it cool down by spread outing and spread the cool air to the environing it.Then, infrigidation and air conditioning system should necessitate four constituent. That four constituent was compressor, condensor, enlargement valve ( metering device ) and evaporator. This constituent used widely in simplest or most complex infrigidation system.hypertext transfer protocol: //www.movacs.

Meanwhile condensor is connect to the enlargement valve/device. The enlargement device which is mounted on the indoor spiral and located within the plenum of a furnace and blower.
Compressor:Compressor used to increases the low refrigerant force per unit area gas and besides it temperature. High force per unit area gas ( refrigerating ) will distill quickly in the capacitor.Capacitor: A A A A A A A A A A A A A A A AHigh temperatures of refrigerant go through the cold air across capacitor five and tubing by fan. It will ensue refrigerating become high force per unit area liquid without alteration the force per unit area.FILTER DRIER: A A A A A A A A AFilter used to take wet. The most ground is to avoid corrosion which leads to the terrible system failure.
A A AEXPANSION DEVICE: AExpansion valve is a constituent that used to command refrigerating flow into the evaporator thereby commanding superheated air at the mercantile establishment of the evaporator.EVAPORATOR: A A A A A A A A A A AAn evaporator used to vaporize liquid to gas by take downing the force per unit area until it boiling point. Since the evaporating temperature is lower than environing ; so air is seeking to chill.
Heating Ventilating Air Conditioning and Refrigeration ( HVACR ) system in Agriculture Industries
HVACR system in Malaysia agribusiness more directed to the storage of natural stuffs or storage of agricultural merchandises that do non last long.Among them are such as piscaries beginning, meat and veggies and fruit. Additionally, HVCAR besides used in farm animal agriculture sector. HVACR give benefit to Malaysia agribusiness industries to assist husbandmans increase the productiveness and more competitively.hypertext transfer protocol: //www.dof.gov.

HVACR system used in Malaysia agribusiness
Fisheries
Imagine fishermen back to the breakwater at 4 or 5 in the forenoon with a batch of fish stocks. Without good refrigerant system the fish will be bad if non sold instantly. Refrigerant really of import for fisherman to hive away the fish. Without deep-freeze it will do uneconomical to the fisherman because fish freshness slice without proper storage and do non durable.hypertext transfer protocol: //2.bp.blogspot.com/-kdHh9T43QXY/Tez24YjiRZI/AAAAAAAAA_s/ANVjlkGVrfE/s320/Prefab-Cold-Storage.jpgFigure: Cold StorageFish are susceptible to nutrient spoilage. Particularly in tropical parts like Malaysia is comparatively high temperature.
However, fish life can be extended with storage in a cold Storage. Even fish can be stored frozen for several months, until the fish can be thawed when needed and further processed by consumers. Stream of frozen nutrient concatenation or cold concatenation by and large consists of freeze, storage in a cold warehouse, transported by refrigerated autos, exhibited in the cold cabinet at the food market shop, finally stored in the electric refrigerator deep-freeze at place.Other application used for agribusiness in Malaysia is multipurpose drier machine Fishery Products.
This machine can dry merchandises such as seaweed, fish, crackers and anchovies. Even the Engineering has besides tried other merchandises such as chili and maize by utilizing a paradigm machine.hypertext transfer protocol: //www.dof.gov.

Plantation and output harvest
Dumping of the output harvest in the market was doing the wasteful in agribusiness industries. Therefore, the Federal Agriculture Marketing Authority ( FAMA ) was presenting the `` Blast Freezer '' refrigerant system that allows the output of harvest can be used for a long clip since twelvemonth 2007. By utilizing this system, agriculture merchandise can widen the clip to damage. Furthermore, this system really suited used for storage the tropical fruit in a period clip. As illustration, durian can be used for a twelvemonth utilizing blast deep-freeze system as storage before export or used it for other activities. This system besides can utilize for livestock merchandise.Livestock
Presents, air conditioning systems besides apply in the farm animal coop or barn. This is avoid local occupant receive air pollution from the coop or barn. In old ages 2002, Tan Sri Mohd Isa Abdul Samad was declared that province authoritiess require all barns in Negeri Sembilan must put in air conditioning system in their barn. Air conditioning system can avoid air pollution job that produce from farm animal activities. Since air conditioning system can used to sublimate and cleanliness the air, the air pollution job can be countered.hypertext transfer protocol: //telecentre.my/kampungtebukpulai/images/stories/Perikanan.jpgFigure: Barn with air conditioning system
