JLSF-20HP Air Cooled Water Chiller Frequency Conversion Constant Temperature

JLSF-20HP Frequency Conversion Constant Temperature Chiller, Precise Temperature Control

Product Description:

Variable Frequency Constant Temperature Chiller is a refrigeration equipment used in industrial and commercial applications. It combines frequency conversion technology and constant temperature control technology to enable precise temperature adjustment and energy consumption control according to needs.

Frequency conversion technology refers to adjusting the cooling capacity by adjusting the speed of the compressor in the refrigeration system. Traditional chillers usually use fixed-speed compressors and can only operate at a fixed power and cooling capacity. The variable frequency constant temperature chiller can adjust the speed of the compressor according to actual needs to match the load demand and achieve high-efficiency refrigeration operation.

Constant temperature control technology refers to the precise control of the water temperature of the chiller through accurate temperature sensors and control systems. This technology can ensure that the chiller outputs a constant temperature and is suitable for applications with high temperature requirements, such as medicine, chemical industry, semiconductor and other fields.

Product Features:

Frequency conversion constant temperature chiller has the following advantages:

1. Energy saving and high efficiency: The compressor speed is adjusted through frequency conversion and intelligently adjusted according to the load demand to avoid wastage of energy consumption and improve energy utilization efficiency.

2. Precise temperature control: Using constant temperature control technology, precise control of the water temperature of the chiller can be achieved to meet applications with high temperature requirements.

3. Stable operation: The variable frequency constant temperature chiller can adjust operating parameters in real time according to load changes, maintain stable working conditions, and improve the reliability and stability of the equipment.

4. Save space: Compared with traditional chillers, variable frequency constant temperature chillers are usually smaller in size and take up less space, making them suitable for places with limited space.

In short, variable frequency constant temperature chillers are widely used in industrial and commercial fields and can provide high-efficiency, precise temperature control, stable and reliable refrigeration solutions.

Working Principle:

The working principle of the variable frequency constant temperature chiller can be divided into three main parts: refrigeration cycle system, control system and constant temperature adjustment system.

1. Refrigeration cycle system:
- Compressor: The variable frequency constant temperature chiller uses variable frequency technology to control the speed of the compressor. The compressor is responsible for compressing the refrigerant gas into high-temperature and high-pressure gas.
- Condenser: The high-temperature and high-pressure gas dissipates heat through the condenser, cools and turns into high-pressure and high-temperature liquid.
- Expansion valve: High-pressure and high-temperature liquid enters the evaporator through the expansion valve. The pressure decreases and the liquid evaporates into refrigerant gas.
- Evaporator: The refrigerant gas absorbs heat through the evaporator, thereby cooling the water flow through the evaporator pipes, causing the water temperature to drop.
- Cooling water circulation: The cooling water circulates through the evaporator, absorbs the heat in the evaporator, and then returns to the cooling water unit to continue the cycle.

2. Control system:
- Frequency conversion control: Adjust the speed of the compressor by controlling the frequency converter, and adjust the cooling capacity according to actual needs to improve energy efficiency and save energy.
- Pressure sensor and temperature sensor: The control system monitors the pressure and temperature conditions in the refrigeration cycle in real time through the pressure sensor and temperature sensor.
- Control algorithm: Based on the feedback signal from the sensor, the control system uses a specific control algorithm to adjust the output of the inverter to achieve precise temperature control and optimized refrigeration effect.

3. Thermostat system:
- Temperature setting and feedback: Users can set the desired constant temperature value through the control panel or remote control. The control system monitors the temperature of the cooling water in real time through a temperature sensor and compares the feedback signal with the set temperature.
- Control actuator: According to the temperature difference, the control system adjusts the flow of cooling water by controlling the actuator (such as a solenoid valve) to keep the cooling water temperature stable near the set value.
- Feedback loop: The control system keeps the temperature of the cooling water constant by continuously adjusting the opening of the actuator to achieve constant temperature regulation.

By comprehensively operating the refrigeration cycle system, control system and constant temperature adjustment system, the variable frequency constant temperature chiller can provide precise temperature control according to actual needs while achieving high-efficiency refrigeration operation.
