Strength of 18KW CO2 R744 air source heat pump water heater and heating system EVI for cold temperature -25℃
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 easily formed 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 carbon dioxide heat pump heat exchange component includes a mounting plate, two sides of the mounting plate are inclined with heat exchangers, the ends of the heat exchangers on both sides are connected by end plates, and the end plates and the mounting plate are connected by connecting bolts. In the present invention, the heat exchangers are arranged on both sides, which can form a larger heat exchange area, which is beneficial to improve the heat exchange efficiency of the carbon dioxide heat pump.
Tandem gas-liquid separators for carbon dioxide heat pump systems. The carbon dioxide heat pump system uses a series gas-liquid separator, including a gas-liquid separator, the gas-liquid separator includes a first-stage monomer and a second-stage monomer, and the first-stage monomer and the second-stage monomer are connected through series pipes, The center of the first air inlet and the center of the first air outlet are symmetrically distributed with the axis of the first-stage monomer as the center of symmetry, and the center of the second air inlet and the center of the second air outlet are the same as the second-stage monomer. The axis is the center of symmetry and the center is symmetrically distributed. The line between the center of the first air inlet and the center of the second air inlet is parallel to the line between the center of the first air outlet and the center of the second air outlet. . The utility model has the beneficial effects of being able to effectively avoid the instantaneous return of liquid substances to the compressor too much, preventing the occurrence of the phenomenon of burning cylinders, and ensuring that the working and running requirements are met while not being restricted by the production requirements.
