Low-environment-temperature water generator

Abstract

The invention discloses a low-environment-temperature water generator which comprises a compressor, a condenser, a throttling element, a three-way electromagnetic valve, a one-way valve, an evaporator, a bypass preheater, an air filter, a heat exchange fan, a water tank, a water collecting tank, a water pump and a disinfection and purification device. The compressor is connected with the three-way electromagnetic valve and the condenser and then connected with the one-way valve and the throttling element, only when the external environment temperature is lowered and the evaporator is frosted, the three-way electromagnetic valve opens the bypass preheater, and a part of high-temperature exhaust refrigerant runs through the bypass preheater and exchanges heat with the evaporator to increase the temperature of the surface of the evaporator; and through heat diversion of the bypass preheater, the surface temperature of fins is increased to a proper evaporation temperature, and condensed water is increased, so that the water production range of the water production machine at a low environment temperature is widened. Preheating and conventional technologies are combined, so that the efficiency of the water making machine is improved, and the working condition range of the water generator is effectively widened compared with that of a conventional water generator.

Description

technical field [0001] The invention relates to the technical field of air water production and dehumidification, in particular to a low ambient temperature water generator. Background technique [0002] With the continuous improvement of people's living standards and health awareness, the requirements for drinking water and the environment are getting higher and higher. The air water generators that appear on the market are currently most commonly used to use the principle of vapor compression refrigeration composed of compressors, and the low-temperature and low-pressure liquid refrigerant is vaporized and phase-transformed in the evaporator tube, so that the air on the outer surface of the evaporator It is cooled and forms condensed water, which is collected to form the water source of the air water generator. [0003] In terms of system layout, the evaporator and condenser with the same windward area are often connected in series, that is, the wind generated by the fan ...

Problems solved by technology

The ambient temperature of conventional water generators is between 21 and 30°C, which can meet the use requirements in summer, but it is difficult for conventional water generators to meet the use requirements brought about by the reduction of the environment in spring, autumn or winter.
