Refrigeration and Heating Experimental EquipmentIt is an important tool for simulating and testing the performance of refrigeration and heating systems, widely used in fields such as scientific research, teaching, product development, and quality control. Mainly based on thermodynamic principles for work. Refrigeration equipment achieves the goal of reducing temperature by absorbing heat in the evaporator and releasing heat in the condenser through the refrigerant; The heating equipment, on the other hand, uses reverse circulation to allow the refrigerant to absorb heat in the condenser and release heat in the evaporator, thereby achieving the effect of increasing temperature. These devices ensure stability and efficiency in actual operation by precisely controlling parameters such as refrigerant flow rate, temperature, and pressure.
Refrigeration and Heating Experimental EquipmentCore functional features:
1. Wide temperature range coverage
It can achieve continuous adjustment from extremely low temperature to high temperature, meeting the needs of different experimental scenarios:
Low temperature end: Some equipment can reach a low temperature of -80 ℃ (such as cryogenic testing equipment), suitable for testing the performance of frozen materials and the stability of low-temperature electronic components;
High temperature end: The maximum temperature of conventional equipment is about 150 ℃, and special customized models can exceed 300 ℃ (such as high-temperature heat pump system testing), used to simulate the heat resistance of products in high-temperature environments (such as automotive engine compartment components);
Adjustment continuity: Supports seamless switching of temperature from low to high, without the need to shut down or replace modules, improving experimental efficiency.
2. High precision temperature control and fluctuation suppression
The temperature control accuracy can reach ± 0.1 ℃~± 0.5 ℃ (conventional industrial grade is ± 1 ℃). For example, when testing the performance of air conditioning heat exchangers, it is necessary to accurately control the ambient temperature to avoid temperature fluctuations affecting the calculation of heat transfer efficiency;
Equipped with an "anti-interference system": using PID (proportional integral derivative) intelligent algorithm, high-precision temperature sensors (such as platinum resistance PT100), and efficient insulation layer, it suppresses the interference of external environment (such as room temperature fluctuations and equipment heat dissipation) on the temperature inside the experimental chamber, ensuring temperature stability.
3. Rapid temperature rise and fall capability
Equipped with a "rapid temperature change" function, the temperature rise and fall rate can be adjusted (conventional 5 ℃/min~15 ℃/min, high-speed models can reach 20 ℃/min or more), used to simulate extreme temperature sudden change scenarios:
Example: In automotive component testing, simulate the sudden temperature rise process of a vehicle driving from a cold northern outdoor environment (-30 ℃) into a warm indoor environment (25 ℃) to verify whether the components are damaged due to thermal expansion and contraction.
