Solar photovoltaic heat pump dryer

Abstract

The invention discloses a solar photovoltaic heat pump dryer, which comprises a box body and an air-drying box. Four photovoltaic modules are arranged on the top of the box body, and a control box is arranged on the left side of the box body. There is a sliding door on the front, and a radiant heat pipe is arranged inside the door, a heat pump unit is arranged on the right side of the radiant heat pipe, and six battery boxes are arranged on the upper part of the heat pump unit; Air outlet, and an air outlet is provided on the right side of the air-drying box, and a temperature sensor is installed on the upper surface of the air outlet, and a heat dissipation pipe is provided inside the air-drying box. Since the photovoltaic module can provide power, the set The auxiliary heat pipe can provide auxiliary heat for the heat pump unit. At this time, the heat pump unit raises the heat and transports it to the heat dissipation pipe. At this time, the temperature sensor detects the temperature and starts the supplementary heat pipe, so that the high-temperature gas flows out from the air outlet, and the objects at the air outlet are dried. The object is dried, so the device is worth popularizing.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of solar energy, in particular to a solar photovoltaic heat pump dryer. Background technique [0002] As a non-polluting and clean energy, solar energy is widely used in various fields. For example, using solar energy to dry objects, because the temperature required for drying objects is relatively high, most of the existing drying equipment uses mains power supply, which not only wastes energy , and it also pollutes the environment to a certain extent. Although solar drying equipment appears on the market, it converts solar energy into electrical energy and stores it in the battery, so that a set of equipment requires many battery packs, which further leads to large equipment. The cost is high, and maintenance is inconvenient, and the maintenance cost is high. In addition, heat pumps are also used to dry objects, but heat pumps absorb the low-temperature heat of the air and conv...
