Method for calculating storage capacity of fruits and vegetables in refrigeration house based on respiration heat of fruits and vegetables

Abstract

The invention relates to a method for calculating the storage capacity of fruits and vegetables in a refrigeration house based on the respiration heat of fruits and vegetables; the method comprises the following steps: determining a heat balance state time point of refrigeration house operation according to a characteristic of maintaining a constant temperature state in refrigeration house closed storage operation; then, according to all stable heat factors in unit time forming the heat balance state of the refrigeration house, including the refrigerating equipment refrigerating capacity Qcold, the maintenance structure incoming heat Q1 of the refrigeration house , the fan heating quantity Q2 in the refrigeration house, the heating quantity Q3 of other built-in power equipment in the refrigeration house and the fruit and vegetable breathing heat Q4 in the refrigeration house, calculating the fruit and vegetable respiration heat Q4 in the refrigeration house by utilizing a balance relation that the refrigerating capacity Qcold of refrigeration equipment in the heat balance state of the refrigeration house is equal to the sum of the maintenance structure incoming heat Q1 of the refrigeration house, the heating value Q2 of a draught fan in the refrigeration house, the heating value Q3 of other built-in power equipment in the refrigeration house; and calculating the mass of the fruits and vegetables in the refrigeration house according to the unit mass breathing heat of the fruits and vegetables in the refrigeration house. The beneficial effects are that the calculation process is simple, convenient and accurate, and the accuracy of informatization operation data of the Internet of Things is improved.

Description

technical field [0001] The invention specifically relates to a cold storage storage information technology. Background technique [0002] The use of IoT cold storage technology has greatly improved the development of the fruit and vegetable industry. The existing Internet of Things cold storage monitoring system can monitor the use status of the cold storage in real time. The monitoring content includes the geographical location of the cold storage, the weather conditions of the external environment, the types and reserves of fruits and vegetables stored in the cold storage, the operating temperature in the cold storage, and the real-time consumption of the cold storage. power status, etc. Integrating farmers' cold storage usage information through the Internet of Things can not only effectively supervise and count farmers' fruit and vegetable reserves, but also provide reasonable guidance to fruit and vegetable markets and farmers' planting conditions based on regulatory i...
