A vertical air supply type heat pump constant temperature equipment

Abstract

The invention discloses vertical ventilation type heat pump thermostatic equipment. The equipment comprises a building envelope, a variable cross-section air supply static pressure space, drying areas, a variable cross-section air return static pressure space and an air treatment device. The lower portion of the variable cross-section air supply static pressure space is divided into three layers of drying areas in the airflow direction by an air supply non-uniform pore plate and an air return non-uniform pore plate which are horizontally arranged. The air treatment device is arranged on the outer side of the variable cross-section air return static pressure space. A group of air supply holes is arranged on the upper portion of the interior of each drying room on the top layer of each drying area, and air return holes are arranged below the drying room on the bottommost layer of each drying area. According to the equipment, dry air distribution is improved by means of vertical ventilation of a dry surface, uniformity and stability of airflow on the dry surface are guaranteed, drying efficiency is improved, and energy consumption is reduced.

Description

technical field [0001] The invention belongs to the technical field of building environment and equipment engineering, and relates to an air circulation treatment system, in particular to a vertical air supply type heat pump constant temperature equipment. Background technique [0002] As a large agricultural country in my country, agricultural energy conservation is of great significance in the strategy of energy conservation and emission reduction. Many agricultural and sideline products (including edible fungi) must be dried before and during storage, transportation and processing into food or other daily necessities because they are rich in water (generally with a moisture content of more than 80%), and drying operations generally require Uses a lot of energy. Hot air drying technology is the mainstream technology in the edible fungus deep processing industry, and its production efficiency directly affects the effect of agricultural energy saving in this field. Therefo...

AI Technical Summary

Problems solved by technology

However, the static pressure space of the air supply and return air is small, and the parallel air supply method in the baking workshop cannot fully achieve the effect of uniform and stable air flow organization, and the drying effect of edible fungi is not good.

The air supply port adopts constant air volume, and the same air volume is delivered to different drying spaces, which not only causes waste, but also affects the drying effect of edible fungi
