Introduction The refrigeration system is the most critical component of a cold chain tricycle. NEWBASE offers two primary cooling technologies — compressor-based and thermoelectric (semiconductor) cooling — each with distinct advantages depending on the application. Compressor Refrigeration Systems Compressor systems work on the vapor-compression cycle — the same technology used in household refrigerators and commercial cold storage. How It Works 1. Refrigerant gas is compressed, raising its pressure and temperature 2. Hot gas passes through a condenser coil, releasing heat 3. Cooled liquid refrigerant expands through an expansion valve, dropping temperature 4. Cold refrigerant absorbs heat from the cargo compartment via the evaporator Advantages Deep-freeze capability: Achieves -22°C for frozen […]

The Urban Logistics Challenge Cities worldwide face mounting pressure to reduce traffic congestion, lower carbon emissions, and improve delivery efficiency. Traditional refrigerated vans struggle with: Restricted access zones in city centers Traffic congestion that delays deliveries High operating costs from fuel and maintenance Parking difficulties that waste driver time NEWBASE refrigerated tricycles address each of these challenges directly. Cost Comparison: Tricycle vs. Van Delivery Daily Operating Costs Cost Category Refrigerated Van NEWBASE Refrigerated Tricycle Fuel/Energy (daily) $25–40 $1.50–3.00 Insurance (monthly) $150–300 $50–100 Maintenance (monthly) $120–200 $20–50 Parking/Congestion Charges $10–30/day $0–5/day Driver License Requirement Commercial Standard Efficiency Metrics A NEWBASE refrigerated tricycle can complete 40–60 delivery stops per day in dense

Executive Summary: The expanding reliance on decentralized urban food systems and temperature-sensitive pharmaceutical distribution requires highly specialized transport assets capable of micro-climate regulation within dense metropolitan configurations. This technical paper provides a rigorous engineering analysis of the electric refrigerated tricycle engineered by NEWBASE (Zhengzhou NewBase Automotive Electronics Co., Ltd.). By evaluating the mechanical dimensions, thermodynamic capabilities of the 650W DC air-cooled refrigeration framework, and the independent dual-energy storage architecture, this document establishes the vehicle’s alignment with contemporary global cold chain compliance standards. 1. Dimensional Architecture and Chassis Engineering The physical footprint of an urban distribution vehicle directly governs its operational efficiency, maneuverability in constrained pathways, and spatial compatibility with standard

Introduction The rapid growth of cold chain logistics has transformed the way temperature-sensitive products are transported worldwide. Fresh produce, frozen foods, dairy products, seafood, pharmaceuticals, vaccines, and biotechnology products all require precise temperature control throughout the supply chain. As urban distribution networks become increasingly complex, logistics operators are searching for transportation solutions that combine refrigeration efficiency, low operating costs, environmental sustainability, and maneuverability. The Electric Refrigerated Tricycle has emerged as an ideal solution for urban cold chain delivery. Compared with conventional refrigerated trucks, electric refrigerated tricycles offer lower operating expenses, reduced carbon emissions, simplified maintenance requirements, and superior accessibility in congested city environments. Developed by NEWBASE (Zhengzhou NewBase Automotive Electronics

By NEWBASE Technical Engineering Team | Published April 30, 2026 | 9 min read To appreciate the sophistication of modern electric truck refrigeration systems like the NEWBASE NBESR-1000A, it is essential to understand the fundamental principles that make cooling possible. The vapor compression refrigeration cycle — the same principle that powers household refrigerators, air conditioners, and traditional transport refrigeration — forms the foundation of all commercial refrigeration technology. The Fundamental Principle: Heat Transfer Against the Gradient Unlike heating, which naturally flows from hot to cold, cooling requires forcing heat to move from a cooler space to a warmer one — against its natural tendency. Refrigeration works on a fundamental physical
