Description

Dehumidifier for preventing liquid impact

Technical Field

The utility model belongs to new trend system field, in particular to prevent dehumidifier that liquid hits.

Background

With the continuous development of the fresh air industry and the continuous promotion of the appeal of people to fresh air products, some existing manufacturers begin to superpose some functions on a fresh air unit, for example, a dehumidification module is added on the basis of a fresh air dehumidifier.

Compared with other direct expansion type refrigerating systems, the dehumidifier dehumidifying module is also composed of four refrigerating parts. The compressor discharges high-temperature and high-pressure gaseous refrigerant, the gaseous refrigerant is condensed by the condenser to become gaseous refrigerant or gas-liquid mixed refrigerant close to the ring temperature, the refrigerant enters the evaporator after being throttled and evaporated at low temperature, and the low-temperature and low-pressure refrigerant is absorbed by the compressor, so that the refrigeration process is completed.

The existing refrigeration system of the dehumidifier is formed by simply connecting 4 large parts of a conventional refrigeration system and comprises a compressor, a condenser, a capillary tube and an evaporator, wherein the condenser is connected with the compressor through a compressor exhaust pipe, and the evaporator is connected with the compressor through a compressor return pipe. To ensure dehumidification, it is desirable to have a relatively small temperature rise at the evaporator outlet versus the inlet at nominal operating conditions. In the case of low outside air temperature, the required refrigerant quantity is reduced, but the refrigerant quantity of the injection system cannot be changed, so that the refrigerant cannot be completely evaporated in the low outside air temperature, a part of the refrigerant is sucked back by the compressor in a liquid state, the return air of the compressor has no superheat degree, and a heat-insulating sleeve is wrapped on the return air pipe in order to prevent the return air pipe from being condensed. This results in the refrigerant returning to the compressor in liquid form when the refrigerant is not completely evaporated in the evaporator, causing liquid impact damage to the compressor.
