Portable Metal Detector for Airport with Backup Battery
Heat Pump For Greenhouse Heating Introduction to GENT heat pump for greenhouse heating The heat pump heating unit is a single-heat air source heat pump that uses air as the heating source and absorbs heat from the air to prepare hot water, thereby achieving indoor space heating. Therefore, this unit can meet the needs of indoor space heating. There are many new greenhouses in the agricultural field that need to accurately control the temperature in the greenhouse and have the need for heating in the greenhouse, so agricultural users can consider using this unit. Working principle and system composition The core components of the Air Source Heat Pump Heating system are the compressor, evaporator, condenser and expansion valve. The air heat source heating unit absorbs low-temperature heat energy from the air, releases it into the greenhouse after being compressed and heated, thereby transferring the heat from the outdoor air to the room, raising the indoor temperature, and achieving indoor space heating. Core advantages 1. High efficiency and energy saving Compared with traditional electric heating or coal-fired heating, the energy-saving efficiency of air source heat pump greenhouse heating can reach more than 50%, and the energy utilization efficiency is high. 2. Low-carbon and environmentally friendly The air source heat pump heating system does not rely on fossil fuels, and there is no exhaust gas or smoke emission during the operation of the unit, which can effectively reduce greenhouse gas and pollutant emissions and meet the development needs of green agriculture. Therefore, users who have corresponding needs, that is, the need for heating in the greenhouse, can consider this unit. This commercial air source heat pump can effectively control the heating cost and operating cost while meeting your heating needs in the greenhouse. heat pump heating system,heat pump heating,air heat source heating,commercial air source heat pump,air source heat pump greenhouse GUANGZHOU GENT NEW ENERGY TECHNOLOGY CO., LTD , https://www.gentgz.com
