Multi-Source Energy Laboratory System Delivered for University Teaching and Research

Introduction

We recently completed shipment of a full multi-source complementary energy experimental system for university energy power engineering laboratories. This complete lab setup integrates solar panels, phase change energy storage experimental units, Water-to-Air Heat Exchangers Apparatus, insulated hot water storage tank, heat exchangers, circulating water pumps and data acquisition & control system, supporting comprehensive teaching and research for renewable energy and multi-energy coupling projects.

Among these core modules, the R306 Water-to-Air Heat Exchangers Apparatus stands out as the key teaching research unit. It enables switching among air source, water source and soil source heat pump working conditions within one single bench, delivering intuitive thermodynamic cycle demonstration and measurable heat pump performance data for engineering thermodynamics, refrigeration principle and heat pump technology courses.

What Is Water-to-Air Heat Exchangers Apparatus?

The Water-to-Air Heat Exchangers Apparatus follows the principle of vapor compression refrigeration cycle. Based on the second law of thermodynamics, it consumes electric work to extract heat from three different low temperature heat sources: ambient air, water medium and soil, then transfers thermal energy to high temperature sides to realize heating function.

The system adopts environment friendly R134a refrigerant with zero ODP value without damaging atmospheric ozone layer. Main circulation components are exposed and neatly arranged on the experimental table. Users can visually observe the full heat pump working loop. Multiple sensors collect real time data including refrigerant pressure, temperature, flow rate, water temperature and compressor power, so students can complete quantitative calculation and comparative analysis instead of only qualitative demonstration.

Different from single source heat pump experimental devices, this bench realizes fast working condition switching via valve groups. Operators can switch between air source, water source and soil source heat pump modes without changing hardware configuration, greatly expanding experimental contents for university labs.

Core Composition & Technical Specifications of R306 Water-to-Air Heat Exchangers Apparatus

The experimental platform consists of refrigerant circulation loop, multi-source evaporator assembly, condenser unit, adjustable electric heating modules, measuring instruments and human machine control panel.

• Evaporator group: Air source evaporator with fin and tube structure; plate type heat exchanger for water source mode; soil source simulation box with adjustable heating power.
• Refrigerant circuit: Compressor, thermal expansion valve, dry filter, R134a turbine flowmeter, high/low pressure pressure gauges.
• Measuring & control: Touch screen HMI, T type thermocouples, water flow meters, power monitoring module, high pressure cut off safety protection (32 bar trigger threshold).
• Auxiliary heating: 0-2000 W adjustable water source auxiliary heater; 0-1200 W adjustable soil source auxiliary heater for simulating varied source side temperature conditions.

Available Teaching & Research Experiments

Designed for energy and power engineering, mechanical engineering and building environment majors, the Water-to-Air Heat Exchangers Apparatus supports a full set of standard experiments:

1. Measurement of compressor heating coefficient COPH under different heat sources
2. Comparison between actual refrigeration cycle and ideal theoretical cycle, drawing P-h (pressure enthalpy) diagram
3. Influence of water source inlet temperature on heat pump heating performance
4. Study on compression ratio impact on heat pump system efficiency
5. Heat pump performance curve test under varied evaporation and condensation temperature
6. Soil source heat pump performance test and soil thermal balance experiment

Students can record pressure, temperature, flow and power data, complete formula calculation, compare performance differences among air / water / soil source modes, and deepen understanding of reverse Carnot cycle, evaporator condenser heat transfer and renewable heat utilization principles.

Key Points When Selecting Water-to-Air Heat Exchangers Apparatus

When purchasing Water-to-Air Heat Exchangers Apparatus for university laboratories, focus on these practical factors:

1. Multi-source switching capability: Confirm whether the equipment supports air source, water source and soil source mode switch only by valve operation, avoid manual component re-assembly.
2. Measurement completeness: Check real time measurable parameters: refrigerant pressure/temperature/flow, water side temperature and flow, compressor power, to support quantitative data processing.
3. Safety protection mechanism: High pressure cut off, compressor over heat and electric overload protection are essential for student operated teaching labs.
4. Refrigerant selection: Prioritize environmentally friendly R134a with zero ozone depletion potential.
5. Supplier service: Require factory pre-test, on site commissioning, operator training, complete experiment guide documents and long term technical maintenance.
