Dual-temperature cold storage

A dual-temperature cold storage facility consists of a single cold storage compartment divided by partitions to create two separate units with distinct temperatures. Each compartment is equipped with its own set of doors. Designed to meet the requirements for food storage, it features different temperature settings for simultaneous preservation and refrigeration functions. A centralized refrigeration unit supplies cooling, with two evaporators operating concurrently in the storage units. The temperature control system independently displays and controls the temperature in each compartment. Due to the dual-control system, which manages both compartments, the refrigeration is only turned off in one compartment when it reaches the set temperature, and the refrigeration unit ceases operation only when the other compartment also reaches the set temperature. The automatic control system will activate the refrigeration unit for the compartment whose temperature first reaches the set requirement before starting up.

I. Dual-temperature Cold Storage Temperature:

1. (Storage at 0℃ to +8℃) 2. (Refrigeration at -15℃ to -18℃) Part II: Dual-temperature cold storage body:

Insulated cold room bodies are constructed with polyurethane insulation boards, with metal materials like coated steel plates as the surface layer, combining the thermal insulation properties of the material with excellent mechanical strength. They feature easy and quick assembly, long-lasting thermal insulation, simple maintenance, low costs, and high strength-to-weight ratio, making them an ideal material for selecting cold room insulated bodies.  III. Features of Dual-Temperature Cold Storage:

1. Chiller System: A single centralized chilling unit is used for the refrigeration system to reduce operating costs and minimize malfunctions. The chiller units are selected from both domestic and imported original equipment manufacturers. The main components of the cold storage are all chosen from renowned domestic and imported brands, ensuring a rational configuration, stable operation, and high energy efficiency.

2. High-efficiency ceiling-mounted evaporator or tube-type evaporator

3. Control System: Equipped with an advanced microcomputer control system and cutting-edge control methods, featuring a liquid crystal display for internal temperature, power-on time, defrosting time, fan delay time, alarm indicators, and various technical parameters. Operation is simple, providing great convenience for users.

4. Storage Panels: High-quality double-sided color steel polyurethane cold storage panels with small footprint and excellent insulation performance; panel thickness typically ranges from 100mm, 150mm, to 200mm, utilizing polyurethane insulation material. Both sides are coated with plasticized color steel, with the surface processed into invisible grooves. These panels are lightweight, strong, good at heat insulation, corrosion-resistant, and aging-resistant. Assembly is simple and quick, making them an ideal material choice for cold storage and insulated body construction.

5. Installation Process: Utilizing state-of-the-art construction machinery and cutting-edge installation techniques, coupled with stringent quality assurance management, we ensure that every stage of production is meticulously inspected, turning customer requirements into reality.
