A direct evaporative closed external ice-heat pump air conditioner comprises a compressor, a four-way valve, a heat exchanger, an air-cooled heat exchanger fan, a high-pressure receiver, a dry filter, a liquid electromagnetic three- Through the valve, a plurality of expansion valves, a plurality of one-way valve, refrigerant / water heat exchanger, gas-liquid separator, closed ice storage tank, solenoid valve and motor valve control valve composed of outdoor unit and the air conditioning terminal Water, water separator, air conditioning water pressure components composed of air conditioning water circuit. The water in the closed storage tank communicates with the water in the water circuit of the refrigerant / water heat exchanger air conditioner and forms a closed loop external ice melting system. The invention avoids the defects of water flow backflow and electromagnetism valve and electric adjustment to bear the hydrostatic pressure and the like; the evaporation temperature of the refrigeration system is increased by 3-5 degrees Celsius on average, and the energy saving effect is obvious; the ice- Cooler alone for cooling, coolers and ice chiller cooling, cooling mechanism of the five operating modes. Save on heating equipment investment.
European Standard Hoist is a new kind of low headroom product. It creates maximum value for our customers with its excellent durability, quality, and cost-effectiveness. Based on FEM European standard and the Germany DIN standards design and manufacturing, our new energy saving product. Equipped with intelligent safe operation monitoring recorder like the [black box" on a plane which can uninterruptedly record working status and prevent unprofessional operations. Product performance has reached an international advanced level, with eleven patent protections. The machine uses free maintenance modular design, C-type structure arrangement, compact structure, smooth lifting and operation, precise positioning, the maximum lifting capacity of 80 tons. From structure difference, it can be classified running low headroom monorail trolley type and double girders trolley type.
