Energy storage type thermoelectric type air conditioner

Abstract

The invention relates to an energy storage type thermoelectric type air conditioner. The energy storage type thermoelectric type air conditioner comprises a phase change energy storage layer, a thermoelectric module layer, a ventilating heat exchanging layer, a direct current power supply and a control element. A heat transfer liquid medium is full of a phase change energy storage container; a phase change cold storage body and a phase change heat storage body are placed in the phase change energy storage container in a crossed way; a certain number of thermoelectric modules, which are spaced from one another by using heat insulation materials, are uniformly placed on the front wall surface and the back wall surface of the container; a front air duct and a back air duct are arranged between the thermoelectric modules and a housing; the thermoelectric module in the front air duct is used for releasing heat / cold; and the thermoelectric module in the back air duct is used for storing heat / cold. The control element and the direct current power supply are connected with the thermoelectric modules and used for controlling the thermoelectric modules. The energy storage type thermoelectric type air conditioner provided by the invention integrates a phase change energy storage technology and a thermoelectric heating and cooling technology; the energy releasing process is actively controlled while the energy can be rapidly and actively stored; high cooling and heating efficiency is obtained; meanwhile, through the adoption of low load electricity price energy storage and peak load shifting, requirements on storing cold to supply cold in summer and storing heat to supply heat in winter can be simultaneously met; and the operation cost is also effectively reduced while a comfortable indoor environment is created for users.

Description

Technical field [0001] The invention relates to a cold storage / heat type air conditioner combining phase change energy storage technology and thermoelectric technology, and belongs to the technical field of air conditioning refrigeration. Background technique [0002] With the improvement of people’s living standards, more and more electrical appliances enter the homes of ordinary people. Most of these electrical appliances are used during the peak power consumption during the day, and the frequency of use drops sharply after the early morning. This makes the originally very serious power supply "peak" The contradiction between "-valley" is more prominent, and the difference between peak power consumption and low power consumption load is getting bigger. Current cooling and heating split air conditioners cannot effectively use low-valley electricity for cooling and heating, so they cannot make full use of the peak-valley price difference, and the operating cost is high. Energy s...

Problems solved by technology

Although the device integrates cold storage and heat storage, it is a passive cooling and heating supply. During this process, the temperature is not easy to adjust and control, the heat dissipation efficiency is unstable, and the heat dissipation efficiency is not high.

It can be seen that although the above invention patent has the function of heat storage and cold storage, it is not perfect and complete, and the heat dissipation efficiency is unstable during the heating and cooling stages, and the temperature is not easy to control
