A direct expansion solar heat pump air conditioning and hot water system, the direct expansion of solar heat pump and ice storage air conditioner organically combined, mainly by the solar collector / evaporator, compressor, condenser, electronic expansion valve, four commutation Valves, hot water tank, hot water tank, air conditioning terminal devices and system control components. Solar collector / evaporator with no cover, the bottom of the insulation, the surface of the solar radiation absorbing material flat-type collector, the summer as a radiation radiator and heat pump condenser. Accumulator adopts closed pressure storage tank, built-in efficient heat transfer equipment, heat storage in winter and ice storage in summer.

Application Prospect: The system of the present invention integrates many functions such as winter heating, summer air conditioning and year-round domestic hot water supply and the like, has the advantages of good applicability, high equipment utilization rate, remarkable energy saving effect, long service life, high technical and economical performance, etc. Advantages, is a green building complex energy system, applicable to most of our urban and rural construction.

Capital Construction Drilling Rig which is Anchor Drilling Rig Crawler Drilling Rig for Small Space Anchoring pile construction.

The Drilling Rig is designed for working in narrow spaces, such as tunnel, culver and foundation ditch. With its rotating-percussion rotary head, it is suitable for drilling in stratum formations of sticky clay, sandstone as well as partially decomposed rock stratum. With down-the-hole hammer bit, it can drill in hard rock formation efficiently.
