Structure of hot and cold water plants

For heating and cooling water plants with Block

• For the hot chamber

Equipped with an electric heating bar with a capacity of about 500W and with a relay to control the water temperature from 85 – 95 degrees Celsius .

The water temperature is below 90 degrees, the relay turns on the heating rod and when the water temperature is over 95 degrees, the relay disconnects the heating rod , and a second relay is arranged to protect the heating rod when the heating rod temperature is too high.

• For the cold compartment

Arrangement of coils for water cooling. To cool water, there must be a refrigeration system similar to a refrigerator, including block, condenser, evaporator, electronic chip system and capillary.

The cooling system in this compartment has a few differences as the block is smaller, the evaporator is a spiral tube to cool the water. To control the cold water temperature at a temperature of 6 – 10 degrees Celsius , the manufacturer has arranged a thermal relay to disconnect the compressor .

When the temperature reaches 6 degrees Celsius , the relay automatically disconnects, when the temperature exceeds 10 degrees Celsius , the relay will close. The general productivity of hot and cold water plants is as follows: Cooling water about 1 liter/h – 2.5 liters/h , heating about 5 liters/h .

The hot and cold water plants are also designed with a number of handy features: a switch with signal lights for power, air conditioners, heating rods, a grounding safety device for equipment to facilitate the process. usage, avoid leakage of electricity and save energy.

For water plants using electronic chips

Electronic circuit provides 12V DC power to the cooling chip (semiconductor). One side of the cooling chip will generate cold heat, it is close to the aluminum plate mounted in the cold water tank, the cold aluminum plate will cool the water.

The other side of the cooling chip will give off hot heat and it is attached to the heatsink, when operating the cooling fan will suck hot air and blow it out.

When the cold temperature reaches from 8 – 15 degrees Celsius , the temperature sensor of the water plant will signal the circuit to stop supplying power to the cooling chip. This process is repeated during the water use of the hot and cold water plant.

Working principle of hot and cold water plant

Heating chamber unit

This unit is equipped with a water heater with an average capacity of about 500W , and a 2-bar relay unit to control the temperature of hot water ranging from 90 – 95 degrees Celsius .

• The first relay bar is responsible for automatically opening (when the hot water temperature is below 90 degrees Celsius ) and disconnecting the heat source (when the temperature of hot water reaches 95 degrees Celsius ) of the heating rod.
• Second relay bar : Automatically disconnects the heat source to ensure the safety of the machine and the user in case the temperature of the heating rod is too high.

Refrigeration compartment parts

This unit is equipped with cooling technology by electronic chip or by Block to cool water.

Some modern and more advanced hot and cold water plants are also equipped with RO membranes to effectively filter water and bring purer water.

Classification of hot and cold water plants by technology

Based on the operating principle of the machine, hot and cold water plants are divided into 2 types: Block and electronic chip cooled hot and cold water plants.

Hot and cold water plants work based on Block

This technology uses a compressor (Block) with one or two pistons , which maintains the evaporative and condensing pressures of the refrigerant or in other words cooled by gas. The cooling capacity of this hot and cold plant is deeper with a temperature of 5 – 10 degrees Celsius and meets high demand for use.

Advantage

• High durability is widely used in offices, schools, families,…
• Energy saving.
• Capable of supplying hot and cold water continuously to meet high demand.
• Deep cooling like cooling in a refrigerator, superior to electronic chip technology.

Defect

• The price is expensive from 5 to 15 million compared to hot and cold water plants with electronic chips (price updated on June 25, 2022 ).
• When the Block breaks, the replacement cost is also more expensive.

Hot and cold water plants operate based on electronic chips

This hot and cold water plant works based on the way of laser cooling. The mechanism works by trapping and cooling atoms or ions. This method, called Doppler, is the premise to reduce the temperature of the semiconductor, helping to create chips that handle water temperature.

Hot and cold water plants cooled by electronic chips have the ability to cool quickly but the cold temperature is not deep, suitable for households and units with a small number of users .

Advantage

• The price is quite “soft” from 4 to 10 million (updated price on June 25, 2022 ), which is easier to choose and buy.
• If damaged, you just need to replace other electronic chips, which can be more economical than replacing Block technology.

Defect

• Poor heating and cooling capacity: The hottest water temperature reaches about 80 degrees Celsius , the cold temperature is about 15 degrees Celsius .
• Lower durability than hot and cold plants with Block.
• Higher power consumption.

Classification of hot and cold water plants by water source

Based on the water supply for the machine, hot and cold water plants are divided into main types: Set the bottle, suck the bottle, balance the sound, fight quickly and the RO water purifier.
