Device capable of carrying out normal regulating and controlling in constant temperature and humidity field by way of energy storage under condition of disconnecting power grid

Abstract

The invention discloses a device capable of carrying out normal regulating and controlling in a constant temperature and humidity field by way of energy storage under the condition of disconnecting a power grid, which comprises a constant temperature and humidity storage space, an electric refrigerating / heating system, a cold and heat storage system, a temperature and humidity regulating system, and a PLC (programmable logic controller) constant temperature and humidity control system, wherein the constant temperature and humidity storage space, the electric refrigerating / heating system, the cold and heat storage system and the temperature and humidity regulating system are all provided with temperature and humidity sensors which are connected to the PLC constant temperature and humidity control system; meanwhile, the device disclosed by the invention is provided with an energy storage device, an energy storage material and a battery which are combined with a heat exchanger, a constant temperature and humidity regulating system, a refrigerating / heating humidifying circulation system and an automatic PLC temperature and humidity control system so as to form an energy storage type automatic constant temperature and humidity regulating and controlling system for keeping the constant temperature and humidity of the storage space or a display space within a period that a mains supply is switched on and a designated power failure period, wherein the refrigerating / heating circulation system is implemented according to a principle that refrigeration is preferred.

Description

technical field [0001] The invention relates to an air conditioner that applies phase change energy storage technology to constant temperature and humidity, has the characteristic of disconnecting the power grid to maintain normal operation, and belongs to the field of cultural relics protection system equipment. Background technique [0002] The storage protection and display protection of precious cultural relics have very strict requirements on the environment, and there are corresponding standards for the temperature and humidity of different collection and display environments in the world. Therefore, the display of cultural relics and the stable control of temperature and humidity in the storage space are the key technical problems to be solved by the showcase. At present, in the process of cultural relics display and collection protection, the temperature and humidity control equipment in the field of constant temperature and constant humidity adopts the method of sem...

AI Technical Summary

Problems solved by technology

This control mode is difficult to overcome the dependence on the power grid and the characteristics of the device itself. For example, the frequent start and stop of the refrigeration compressor motor will cause the temperature rise of the motor to be too high and the refrigeration compressor motor will be damaged. The electric heater will turn on and generate heat slowly and cut off the power It is difficult to overcome the thermal inertia that continues to heat up later, and it is difficult to achieve precise control goals. In the event of accidents such as power outages, unexpected losses will occur to cultural relics

Especially in some museums and archives, due to the strict requirements of cultural relics management, there is a management system for power supply at night and during the day. None of the existing products and technologies can meet these requirements.
