Abstract

This invention relates to the field of heat exchange equipment technology, specifically a dual-effect cooling and heating unit, comprising an intake chamber, a heat exchange chamber, a vortex tube, a fluid channel, and a drain chamber. The bottom end of the intake chamber is connected to the heat exchange chamber via a first electrically controlled valve. Heat exchange tubes are installed inside the heat exchange chamber, and a liquid separation device is installed at the bottom of the heat exchange chamber. An exhaust pipe is installed on the side of the heat exchange chamber, and the air inlet of the vortex tube is connected to the exhaust pipe. The fluid channel is connected to the heat exchange chamber, and the longitudinal section of the heat exchange tube can be closely fitted with the longitudinal section of the fluid channel. The hot air outlet of the vortex tube is connected to the fluid channel. The drain chamber is located at the bottom end of the heat exchange chamber and is connected to the heat exchange chamber. Its unique movable, closely fitted heat exchange tubes can increase the contact time between the heat exchange tubes and hot air / high-temperature steam, thereby improving heat recovery efficiency. It is applicable to hot air / high-temperature steam generated by air-cooled or water-cooled coolers such as evaporative coolers, spray cooling towers, or finned heat exchangers. The equipment has a wide range of applications and can recover heat from these devices.
