Principle Introduction of CO2 R744 Air Source Water Source Heat Pump 37kw commercial usage for hot water
The carbon dioxide heat pump includes a shell, a partition plate is horizontally arranged in the shell, a heat exchanger assembly is fixed above the partition plate, and the heat exchanger assembly includes heat exchangers arranged obliquely on both sides of the partition plate, and the heat exchanger assembly is arranged above the heat exchanger assembly. There is a fan. In the present invention, a transverse baffle is arranged inside the casing, the baffle divides the casing into upper and lower spaces, the heat exchanger assembly is installed above the baffle, and the pipeline system and the circulation system are installed in the space below the baffle , The heat exchanger assembly and the pipeline system are separated by the partition plate to avoid the convection between the heat exchanger and the pipeline system, thereby preventing the mutual influence between the two, which is conducive to the normal operation of the carbon dioxide heat pump
The adopted heat pump system involves a gas-liquid separator for a carbon dioxide heat pump system. The gas-liquid separator for carbon dioxide heat pump system includes a cylinder body with an air inlet and an air outlet. The air inlet is provided with an air inlet pipe, and the air outlet is connected with an oil return pipe. The oil return pipe is in a "U" shape. One end of the oil return pipe is communicated with the air outlet, the other end of the oil return pipe is suspended in the air and staggered from the axis of the intake pipe, and at least one oil return hole is radially arranged at the turn of the oil return pipe. The utility model has the beneficial effects of effectively realizing the gas-liquid separation function of the carbon dioxide heat pump system, the liquid that is the mixed state of lubricating oil and carbon dioxide liquid returning to the compressor smoothly at a constant flow, avoiding the occurrence of "liquid strike" or "burning cylinder" accidents and the like.
