Application of mini chiller | DamaTajhiz HVAC Group

The mini chiller is an air-cooled compression chiller. It has smaller dimensions and lower capacity (less than 20 tonnes of cooling). Due to their capacity, mini-chillers are usually used in small spaces, such as small residential complexes, villas, workshops, small industries, etc., which want to be used independently, without the need for a central machine room, and can be installed on the terrace, in the yard or on the roof (with the possibility of airflow). in the courtyard or on the roof (naturally with the option of airflow to appropriate locations thanks to the cooling power of the mini-cooler).

Like the chiller, the mini-chiller is based on the compression refrigeration cycle. It is used to cool the circulating water in systems such as air conditioners, and fan coils or in industrial processes, factories and industrial workshops. Mini-chillers are also used for heating, in the form of rooftop packages in the colder months of the year, using plant room equipment (such as boilers and burners) or heat pump systems (the reverse of the compression cycle).

Application of chillers in buildings

The main application of mini chillers is in relatively small buildings such as apartments, villas, office units, halls and small restaurants. They are used to cool (or heat) circulating water in other HVAC equipment such as fan coils and air conditioners. Mini chillers for buildings are designed and manufactured in capacities ranging from 2 to 20 tonnes of cooling capacity. Their capacity depends on 4 main parameters: the surface area and cooling load of the site, the temperature of the water entering the system, the temperature of the water leaving it and the flow rate of the circulating water.

To choose the right model and capacity of your mini-chiller, you can contact the air conditioning experts of the Heating Equipment Specialist Group. They will be happy to advise you.

Mini-chillers can be used for heating, using the heat pump principle, with a blower to release hot air into the environment. Of course, as the price of gas in Iran is lower than the price of electricity, the use of chillers for heating is not very cost-effective and is not very useful except in luxury projects.

Industrial application of mini chillers

Using mini-chillers is not limited to cooling buildings. They can also be used in industry. In workshops or production plants such as pharmaceutical plants, food industry, textile industry, metal and plastic industry, health industry, etc., where a lot of heat is generated in their production process or production line, it works continuously, a lot of heat is generated even in the cold periods of the year, so it is necessary to dispose of this heat in some way; because raising the temperature of the industrial environment, in addition to raising the temperature of the indoor space, it causes damage to industrial equipment and parts and it results in exorbitant costs.

For this purpose, it is necessary to use equipment for cooling industrial environments, and the most widely used of them is the industrial mini chiller.
The working process of the industrial chiller is that the cold water produced by the chiller enters the heat exchanger and after circulating, absorbs the heat and returns to the chiller to cool the water again. "In general, industrial chillers are air-cooled and do not need a cooling tower.

Advantages and disadvantages of mini-chillers

Some of the advantages of using mini-coolers are the following

• Possibility of independent temperature control by fan coil and thermostat in each room
• Independence of the system if the unit fails and the possibility of calculating the cost of electricity consumed separately for each unit
• No need for a cooling tower and no continuous water consumption (due to the air conditioning of the mini-chiller)
• Small volume, small footprint and easy transportation
• The efficiency of the scroll compressor, which has less friction, less noise and a lower price
• Can be used in any hot and dry or hot and humid climate
• It does not need to be installed in the engine room and can be installed on the terrace, in the yard and on the roof of buildings.
• It can be modularised. The cooling capacity of each mini chiller can be increased gradually and step by step.
• One of the disadvantages of the mini-chillers is that they do not cover all the cooling and heating needs of the large spaces in which they are installed.
