detailed description

Below in conjunction with accompanying drawing 1～4 and specific embodiment the utility model is described in further detail.

The utility model provides a space energy drying room, specifically, it is an improvement of the publication number CN104949474A and the patent name "a drying room utilizing solar energy". It mainly uses air source heat pump to direct heat, including air source heat pump, drying room 1, heating room 2 and lighting insulation room 3, drying room 1 and heating room 2 are located in lighting insulation room 3, heating room 2 and drying room 1 Adjacent, the heat pump condenser 5 of the air source heat pump is set in the heating room 2, and the heat pump evaporator 4 is set inside the lighting and heat preservation room 3, and its air inlet side is located in the daylighting and heat preservation room 3 of the drying room, as shown in Figure 1 In the figure shown, the top of the heating chamber 2 communicates with the drying chamber 1, and a circulation fan 9 is arranged between them to allow the air in the heating chamber 2 to enter the drying chamber 1. Make the air in the daylighting and heat preservation room 3 enter the heating room supplementary air door 10 of the drying room 1 through the circulating fan 9 .

In order to make full use of solar energy, the drying room of the present utility model adopts PC solar panels 12 to build, that is, in Fig. Less than one heat storage bag 8, the heat storage bag 8 is placed on the drying room roof 7 and the heating room roof 13, and the heat storage bag 8 is equipped with a mixed liquid medium, and its medium components are prior art.

The utility model is also equipped with an intelligent control system, which includes a controller, a display screen connected to the controller, a temperature probe, a humidity probe, a start-stop switch of a circulating fan, a start-stop switch of a supplementary air fan, an air source heat pump, and a plurality of temperature probes. One or more are installed in the lighting insulation room, drying room and heating room to collect the current temperature and humidity of each room in real time, and the display screen can display the currently collected temperature and humidity signals in real time.

The working principle of the present utility model is as follows: a drying room is built by using PC sunlight panels. When the weather is fine during the day, the temperature in the lighting and heat preservation room 3 is raised by the direct sunlight. If the temperature detected by the temperature probe located in the drying room is low If it is lower than the set threshold, the air with a higher temperature in the lighting and heat preservation room enters the heating room through the supplementary air door 10 of the heating room, and is heated to a suitable temperature by the condenser and enters the drying room to heat the temperature of the drying room, because the air in the lighting and heat preservation room The temperature is higher than the external temperature, and the energy consumption for heat exchange is less, which can effectively save energy, or conduct heat exchange through the evaporator of the air source heat pump, increase the temperature in the lighting and heat preservation room, and enter the drying room through the supplementary air door of the heating room; or During this process, if the sunlight is not strong or the sun goes down, the heat storage bag 8 will release the heat stored therein, and the high-temperature air in the heating chamber will enter the drying chamber through the above process to dry the articles.

In the utility model, a moisture-discharging louver 6 connected with the daylighting and heat preservation room 3 is arranged at the lower part of the drying chamber 1, and the moisture-discharging louver 6 is arranged opposite to the heat pump evaporator 4. After 14, when dehumidification is carried out to the air inlet of the evaporator through the dehumidification louvers 6, the high-temperature humid air is absorbed by the air inlet of the evaporator, and sufficient heat exchange is performed, and the hot air is sent into the heating chamber again, which effectively improves the heat dissipation. The efficiency of the exchange reduces the loss of heat. And when the humidity in the drying chamber detected by the humidity probe reaches the required humidity, it means that the drying is completed. At this time, the controller controls the circulation fan 9 to stop filling hot air into the drying chamber.

When the air temperature in the daylighting and heat preservation room 3 is higher than the temperature threshold set in the controller, the controller controls the supplementary air blower 11 arranged on the wall between the daylight heat preservation room and the drying room 1 to fill in a large amount of outside air. Neutralize the hot air inside.

When the utility model is built, the daylighting and heat preservation room is a support structure with galvanized square pipes as the skeleton. When laying the PC sunlight board, it is fixed with self-tapping wires, and sealant is applied at the seams, so that the whole is rainproof, windproof and airtight. . As shown in FIG. 3 , a heat pump inspection door 15 is also provided in the heating chamber to facilitate inspection and maintenance of the heat pump condenser.

In the utility model, the evaporator of the air source heat pump is placed in the lighting and heat preservation room, so that the indoor temperature is always higher than the temperature of the natural environment outside. The temperature of the outlet refrigerant increases, the power consumption of the compressor decreases, the COP of the heat pump increases, and the power consumption decreases, achieving a more energy-saving effect. In addition, the heat storage bag placed on the top of the drying chamber has a good heat absorption and heat preservation effect, and significantly reduces the heat dissipation at the top of the drying chamber.

The present invention adopts two kinds of heat source systems, the arched solar energy daylighting and heat preservation room and the air source heat pump, the air source heat pump is the main heat supply, and the solar energy is the auxiliary heat supply, and the two complement each other. Especially during the daytime in late spring, summer and early autumn, for the drying and processing of general agricultural products (drying temperature between 30 and 40°C), almost all solar energy can replace the air source heat pump for heating. Except for the energy consumption of the circulation fan, the others consume almost no electricity. And because the utility model makes full use of green, clean and free solar energy and air energy, it not only significantly reduces the power consumption of drying, but also does not discharge any pollutants during the drying process, and the working environment is very clean.
