Product Description
This unit is designed for teaching experiments in heat pump-related disciplines, including Engineering Thermodynamics, Refrigeration Equipment Principles, and Heat Pump Technology. It supports experiments on compressor heating coefficient, effects of water source temperature on heat pump performance, influence of compression ratio on efficiency, performance curves under varying evaporation/condensation temperatures, and plotting of p-h diagrams.
Based on the second law of thermodynamics, the system transfers heat from low-temperature sources (water, air, ground) to a high-temperature heat sink by consuming electrical power, achieving heating.
All refrigeration and heating cycle components are clearly visible and neatly arranged on the bench. Key parameters—refrigerant flow, pressure, temperature, water temperature, compressor power, etc.—are displayed in real time on the screen.
Experimental Functions
1
Measure input electrical power, output heat, and conversion efficiency.
2
Plot refrigerant performance curves under different evaporation and condensation temperatures.
3
Draw the actual vapor compression cycle on a p-h diagram and compare it with the ideal cycle.
4
Verify energy balance of the entire cycle system.
5
Evaluate the effect of compressor compression ratio on compression efficiency.
6
Determine the overall heat transfer coefficient between evaporator and condenser.
7
Analyze the influence of static water sources and flowing water sources on heat pump efficiency.
8
Study the effects of filler composition (soil, sand, water) on heat pump efficiency.
9
Investigate the influence of moisture content in soil/sand on heat pump efficiency.
10
Support extended research on integrated energy systems including phase-change thermal storage, multi-energy complementation, and energy storage.

FAQ
Is your company a manufacturer or a trading company?
We are a direct source manufacturer with independent R&D, production and quality inspection workshops, and have years of expertise in the university laboratory equipment sector.
What payment methods are supported for overseas orders?
We accept T/T (Telegraphic Transfer) and irrevocable sight L/C (Letter of Credit). Formal commercial or proforma invoices are issued for all orders, with a transparent and traceable process.
What is the production and delivery cycle for the equipment?
Standard models: 45-60 days. Expedited production is available for urgent orders with priority scheduling, and the exact lead time is negotiable.
Do you support product customization?
Customization, OEM and ODM services are available. We can adjust parameters, structure, size and functions as required, and accept private labeling production.
How do you ensure the safe transport of the equipment?
Export-grade triple shockproof and moisture-proof packaging (shockproof foam + thickened carton + plywood wooden case) with warning labels attached.
Does the product come with a warranty? Are spare parts included?
All products come with a 2-year free original factory warranty, and common wearing parts are provided free of charge during the warranty period.
Overseas After-Sales Support：
• 7×24h remote technical support and free operation training with one-on-one engineer guidance;
• Free urgent air shipment of replacement parts for non-human-induced quality defects within the warranty period;
• Lifetime technical consultation and cost-price spare parts supply after warranty;
• Bilingual manuals, operation videos and experiment guides are included for easy use by beginners.
How do you control product quality before shipment?
Strict three-level quality inspection is carried out before delivery:
1. Raw Material Inspection: Full inspection of core components to control precision;
2. In-Process Inspection: Special personnel monitor each process to avoid defects;
3. Final Shipment Inspection: Power-on testing and precision calibration, with official inspection reports issued; factory inspection and remote inspection are both supported.
