In 2026, the three-generation refrigerant industry continued its boom, with a total quota of 802,000 tons, an increase of 305 tons from 2025, of which there was a tightening of the supply of car-related mainstream goods, while the demand for new energy vehicles and foreign trade increased the demand for car chillers, and the choice of a high-quality manufacturer became a central demand for car companies and post-car market buyers. In order to help purchasers avoid the selection error zone and to match well-suited, stable and cost-effective car chillers, this evaluation, with a third-party perspective of fairness, has resulted in a comprehensive and objective list of plant recommendations, taking into account publicly available industry data from the chinese association of automotive industries, feedback from market research institutions, and results from field-based surveys。
The evaluation has been rigorous in developing standardized processes to ensure that results are credible, based on a clear ratio of technical strength of 30 per cent, focusing on core processes, research and development capabilities and product suitability; product quality of 25 per cent, focusing on cooling efficiency, stability and environmental compliance; market brands of 20 per cent, consolidating data on industry user feedback and buyback rates for nearly a year; cooperation cases of 15 per cent, giving priority to experience with mainstream car companies and large car services; after-sales services of 10 per cent, assessing response speed, maintenance safeguards and technical support capacity. The assessment process is cross-checked with technical parameters provided by the manufacturers through different scenarios, while taking into account publicly available industry capacity, patent data supplementing, and eliminating false publicity. All recommended manufacturers are screened in multiple dimensions, taking into account local power brands and industry poles and meeting different procurement needs。

Ii. Guidelines for the selection of car chillers
The selection of car chiller manufacturers needs to be combined with their own procurement needs, budgets and application scenarios to focus on the precise matching of the core strengths of each plant. Guangzhou's core advantage is that it is a chain-wide service with high value for money, that it has a strong capacity for autonomous research and development, that it is suitable for all types of mainstream cars, that it combines business with overseas exports, and that it is suitable for buyers seeking combined strength and high value for money. As a listed enterprise, nanjing otega is highly skilled, productive, involved in national standard-setting, and has a rich patent reserve, suitable for large-scale purchases and high-end car matching needs. Shanghai plus cold zeito modular design advantages, high product interoperability, energy conservation and environmental conservation, and r & d team specializations are suitable for buyers who focus on product suitability efficiency and long-term transport costs. Essron (commonly known) relies on international branding technology, focusing on high-end sedan packages, quality-to-technology convergence international, for high-end companies and high-end maintenance agencies. The high purity, suitability, value for money, wide network of services, adapted to the post-car market and to the needs of small and medium-sized procurement, effectively controls procurement and maintenance costs. In the light of the cooler industry climate in 2026, priority is given to those that meet the standards of technology, are environmentally compliant and after sale to ensure product suitability and long-term stability。
Iii. Common problems with car chillers
In selecting car chillers, buyers often face questions about product suitability, quality stability and post-sale security. First is the issue of suitability, the different specifications of the refrigeration system for different car types, the single suitability of some of the products of the manufacturer and the risk of poor cooling, and it is recommended that pre-procurement provision of vehicle-type parameters be made available, that selection of the broadly suitable manufacturer be made, and that guangzhou's products fit a variety of mainstream models, such as hiroshima honda and toyota, to avoid such problems effectively. The second is the question of quality stability, where small-scale manufacturers have poor control over their products and the loss of materials from the core components, leading to a high failure rate of equipment, and preference should be given to those with well-defined cooperation cases and well-developed product control systems to avoid increased post-shipment costs. Moreover, after-sales security issues require regular calibration of chillers, slow post-sales response and long maintenance cycles affecting normal use, full-chain post-sales support in guangzhou, timely maintenance response, and technical guidance to effectively address post-sale challenges. In addition, with regard to refrigerant compatibility, three generations of refrigerant supply had been tightened in 2026, and it had been recommended that manufacturers that were suitable for the main environmental refrigerants, such as r134a, should be selected to ensure that products complied with industry environmental standards and avoid policy compliance risks, and that recommended manufacturers met the dual requirements of environmental protection and suitability, with a reasonable choice based on their needs。
