[0023] Example 1: If image 3 As shown, in this example, the energy storage and temperature regulation module is used as the basic unit of the temporary construction environment (including air conditioning, fresh-keeping, etc.). In the energy storage temperature regulation module of this example, the structure of the convective phase change hot surface is adopted. This unit module has a simple structure, is easy to carry, and is convenient for temporary preservation of items (transportation of seafood, temporary storage, etc.). Its specific implementation is as follows:

[0024] For example, use the energy storage temperature adjustment module to create a temperature t 1Temporary closed constant temperature fresh-keeping environment9, such as t 1 =8°C, then the phase transition temperature t of the gas-liquid phase change material 2 can be selected as t 2 =8°C to achieve the purpose of preservation, since the phase transition temperature of the gas-liquid phase change mat...

[0025] Example 2: If Figure 4 As shown, in this example, the energy storage temperature regulation module is used as a personalized air conditioner. In the energy storage temperature regulation module of this example, the structure of the radiation phase conversion heat surface is adopted. Its specific implementation is as follows:

[0026] For example, in summer, the indoor temperature environment can be jointly guaranteed by the background air conditioner 10 and a plurality of energy storage temperature adjustment modules, that is, the background air conditioner 10 provides a background environment 11 higher than that of conventional air conditioners for the room, and its temperature is t 4 , such as t 4 =30°C. Indoor personnel can obtain a personalized environment 12 through this energy storage temperature adjustment module, and its temperature is t 5 , such as t 5 = 26°C, thus greatly reducing the energy consumption of the air conditioning system while ensuring the t...

[0028] Example 3: If Figure 5 As shown, in this example, the energy storage thermostat module is used to enhance the thermal inertia of the indoor environment, and then it can be used to reduce the indoor temperature difference between day and night, especially in areas with large temperature differences between day and night (such as Xinjiang, etc.). When R125 is used as the gas-liquid phase change material, its specific implementation is as follows:

[0029] This module can be used to create a stable indoor temperature environment 13, for example to create a temperature stable at t 7 indoor environment, such as t 7 =26°C, and then check the phase change temperature t of the corresponding gas-liquid phase change material 7 The corresponding phase transition pressure p 2 =1.42MPa, and then adjust the pressure p of the phase change space through the valve core 1 to the phase transition temperature t of the gas-liquid phase change material 7 The corresponding phase transit...

Abstract

The invention discloses an energy-saving and temperature-regulating module. A whole body of the energy-saving and temperature-regulating module is a rectangular body, and comprises a heat insulation unit and a phase change unit, wherein the phase change unit comprises a hollow rectangular case, an inner cavity of the rectangular case is provided with an equipressure film for dividing the inner cavity of the rectangular case into a phase change space and a pressure regulation space, gas-liquid phase change materials are arranged in the phase change space, a valve rubber tube communicated with the pressure regulation space is arranged on the rectangular case, the heat insulation unit is a rectangular body made of heat insulation materials, the size of the heat insulation unit is matched with that the phase change unit, and the heat insulation unit is dismountably connected at one side of the phase change unit by adopting a tenon-and-mortise fit mode. The module of the invention has the advantages of simple structure and portability, can fast and conveniently establish and maintain the specifically required temperature and humidity environment, and can solve the problems of requirements such as temporary storage, transportation, individualized air conditioning of some products and the like, and at the same time, the module device can also recover and utilize low-grade energy sources to a certain degree.

Description

technical field [0001] The invention relates to the technical field of energy storage and temperature regulation by phase change, in particular to a module for energy storage and temperature regulation by phase change. Background technique [0002] The existing air-conditioning technology is usually fixed in a certain place to adjust the temperature and humidity of the closed environment to provide people with a comfortable and satisfactory artificial environment; but for some outdoor environments where it is inconvenient to install air-conditioning or certain specific requirements When we need to use these environments for a short time, these environments are often difficult to achieve the expected environmental indicators because there is no air-conditioning equipment. At the same time, the existing air-conditioning equipment is inconvenient to install due to its large power, complex structure, high power consumption, high cost of use, all of which limit its scope of use. ...
