Description

The invention relates to refrigeration engineering, in particular to chambers for storing vegetables and fruits with the provision of heat and humidity parameters that can be used in the food industry, agriculture; , trade.

The purpose of the invention is to reduce energy consumption and increase reliability in operation.

The drawing shows schematically a refrigeration chamber for storing vegetables and fruit,

The chamber includes heat insulation (body 1, set temperature and relative humidity of the gaseous medium, fan 3, air cooler 4, mounted under it 5 for melt water, impermeable wall 6) are maintained in working volume 2 co-Tdporo. the chamber is removed with a liquid intermediate and evaporative vessels, respectively, 7 and i8, installed outside the housing. A steam generator is used as the evaporative vessel 8. Pipe 9 is connected to the intermediate vessel 7 for charging water, overflow pipe 10 and pipe 11 connecting the sump 5 to the intermediate vessel 7. The evaporating vessel 8 has a float level regulator 12 and a heater 13. The pipe 14 connects the intermediate and evaporating vessels 7 and 8, the pipe 15 is designed to supply steam In working volume 2. Temperature sensor 16 and relative humidity sensor 17 are mounted in housing 1. Intermediate vessel 7 and evaporative vessel 8 are located outside the chamber in a warm room, for example, in the town hall.

Refrigerating chamber works as follows.

Initially, the intermediate vessel 7 and the evaporation vessel 8 through the pipes 9 and 14 and the float regulator 12 levels are filled, for example, with distilled water to a predetermined level. When the temperature of the gaseous medium in the working volume 2 is higher than the set value, which is monitored by the sensor 16, the fan 3 is turned on and the coolant (coolant) is fed into the air cooler 4. The air by the fan 3 is sucked from the working volume 2 of the chamber, passes through the air cooler 4, where it cools and it is drained, and through the channel formed by the housing 1 and the airtight partition 6, enters the working

J volume 2 cameras. If necessary

humidifying the air, which is controlled by the sensor 17, turns on the heater 13. The water in the evaporation vessel 8 is brought to a boiling state and the steam

10 through pipeline 15 enters the working volume of 2 chambers. The capacity of the heater (evaporating steam vessel) is automatically adjusted depending on the humidity.

t5 of the gaseous medium using the sensor 17. The water level in the evaporation vessel 8 is kept constant by means of a float regulator 12 level. The capacity of the intermediate tank and 7 is calculated on the operation of the humidifying device during the defrost period of the evaporator air cooler 4.

The defrosting of the air-cooler evaporator 5 of the body 4 is carried out according to a predetermined program after a certain time. When defrost tala water flows into the pallet 5 and then through the pipeline 11, the water enters the intermediate vessel 7.

30 In the event of overflow of the latter, excess water through line 10 is drained to the sewage system or to a reservoir (not shown) for use. The use of melt water for wet--.

The use of air prevents the formation of scale on the heaters of the evaporating vessel 8.

The use of a steam generator as an evaporative vessel allows moistening of the gaseous medium with steam, which is more expedient to moisten with hot water from an energy point of view. Placing liquid-bone vessels outside the hull and one below the other reduces energy consumption by reducing heat leakage and improves reliability.
