Description

Technical Field

[0001] This utility model relates to the field of building environment control systems, and in particular to a novel variable temperature cold storage air conditioning unit. Background Technology

[0002] A cold storage facility is a facility that uses artificial refrigeration to maintain the internal temperature at low or ultra-low temperatures, enabling the storage, preservation, and transportation of temperature-sensitive items such as food, medicine, and biological samples. Cold storage facilities are widely used in food processing, logistics and transportation, the medical industry, and agriculture.

[0003] However, existing cold storage facilities still have some problems in actual use. For example, large cold storage facilities have a large number of warehouses, each with different items stored and different requirements for temperature and humidity control, which causes great trouble for management. Some warehouses need to be temperature-controlled at different times, and traditional manual operation is prone to errors. Furthermore, it is not possible to detect the failure of the warehouse air conditioning unit in time, which ultimately leads to unstable temperature, resulting in a decline in the quality of stored goods and even spoilage. This not only increases the user's operating costs, but may also lead to increased downtime and affect normal production activities. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a new type of variable temperature cold storage air conditioning unit. By introducing information from the air conditioning unit, alarm information, energy consumption, and recipe modes, it can monitor the temperature and humidity inside the cold storage in real time and automatically adjust the equipment status according to preset parameters.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel variable temperature cold storage air conditioning unit, comprising a host computer, a touch screen, and a central controller. The central controller communicates with the cold storage air conditioners via RS485, using a daisy-chain wiring method. The communication cable is a twisted-pair shielded cable, supporting simultaneous communication for up to 128 cold storage air conditioners. The central controller is used to read the status, alarm information, and energy consumption of each cold storage air conditioner, set relevant air conditioning parameters, and control on / off operation. The touch screen communicates with the central controller via Ethernet and is installed at the entrance of each cold storage unit for convenient and timely adjustment of relevant parameters. The host computer connects to the central controller via Ethernet, reads information and alarm information from the cold storage air conditioning units, and provides functions such as a visual human-machine interface, recipe mode, constant temperature mode, and timed on / off operation.

[0006] Furthermore, all data in the host computer is connected to the Internet and can be viewed through mobile terminals.

[0007] Furthermore, the mobile terminal supports internet-connected mobile phones. By downloading an APP or WeChat official account and logging in with the corresponding account, operators can turn the machine on and off and select the control mode; process engineers can modify formula parameters; and administrators can turn the machine on and off, select the control mode, and modify formula parameters.

[0008] Furthermore, the host computer is connected to the Internet and can be accessed via a webpage. This webpage allows internet-connected computers or mobile phones to log in to the corresponding account through a specific IP address or URL. This enables operators to turn the machine on and off, select control modes, process engineers to modify formula parameters, and administrators to turn the machine on and off, select control modes, modify formula parameters, and manage users.

[0009] Furthermore, the alarm information is sent to the user via SMS through the host computer. The SMS includes: alarm occurrence time, alarm status, and alarm description. The alarm status is divided into: alarm entry and alarm exit. Each alarm has at least 2 messages.

[0010] Furthermore, the control mode includes a recipe mode and a constant temperature mode. In the recipe mode, a single warehouse can support up to 200 recipes, with 100 time periods and temperature settings for each recipe, and a minimum interval of 1 minute. In the constant temperature mode, the control is performed according to the set temperature.

[0011] Furthermore, the timed power on / off settings include: whether the timed power on / off function is enabled, whether it is enabled from Monday to Sunday, power on time period: hours and minutes, and power off time period: hours and minutes.

[0012] This utility model has the following beneficial effects: In this invention, by incorporating information from the air conditioning unit, alarm information, energy consumption, and recipe mode, the temperature and humidity inside the cold storage can be monitored in real time, and the equipment status can be automatically adjusted according to preset parameters.

[0013] In this invention, through precise temperature control (formula mode and constant temperature mode) and timely fault response, the impact of unstable temperature on the quality of stored goods is effectively avoided, and the risk of spoilage and deterioration is greatly reduced.
