The invention relates to a thermal storage type vacuum tube which comprises a tubular glass outer shell, an open end of the glass outer shell is connected with a glass flange, the glass flange is connected with a metal end cover through the hot-pressing sealing technology, a protective cap of an exhaust nozzle is arranged at the other end of the glass outer shell, an exhaust nozzle which is integrally molded with the glass outer shell is arranged in the protective cap of the exhaust nozzle, a metal material box body is arranged in the glass outer shell, a solar energy selective coating is arranged on the outer surface of the box body, space between the glass outer shell and the box body is pumped into vacuum state through the exhaust nozzle, a water inlet and a water outlet are respectively formed on the metal end cover, the water inlet and the water outlet are communicated through a heat exchange tube arranged in the box body, and a working medium in the box body adopts solid-liquid phase change materials with phase change temperature of 60DEG C-80DEG C. The working medium in the box body adopts the solid-liquid phase change materials, when the solid-liquid phase change materialsachieve the phase change point, the materials are converted to liquid state from solid state, and a large amount of heat is absorbed, and the temperature of the phase change materials can be basicallymaintained constant. The thermal storage type vacuum tube can be widely applied in a variety of solar water heaters.

The invention provides an outdoor unit for heat recovery type refrigeration equipment and split type refrigeration equipment. The outdoor unit for the heat recovery type refrigeration equipment comprises a compressor, a heat end heat exchanger and a draught fan and further comprises an outdoor unit shell. The compressor, the heat end heat exchanger and the draught fan are arranged in the outdoor unit shell. The draught fan is arranged between the compressor and the heat end heat exchanger. An air channel is arranged between the draught fan and the compressor. A heat storage type heat exchanger is adopted as the heat end heat exchanger and is provided with a refrigerant pipeline and a heat exchange water pipeline. Use convenience and universality are improved, and the use comfort and experience of a user are improved.
