Problems solved by technology

Due to the differences between the two condensers, the differences in the connecting pipes (including pipe diameter and pipe length), installation differences (including installation height, process), etc., the resistance of the two parallel branches will be inconsistent, and this flow distribution structure cannot be very good. Eliminate or reduce the inconsistency of the resistance of the two parallel branches, so in the application, the refrigerant often flows through only one condenser, and the first distribution method is easy to cause the gas to be diverted directly The uneven pressure behind the valve makes it difficult to smoothly distribute and control the refrigerant flow
[0004] In addition, for constant temperature or heating freezing dehumidification, especially low dew point dehumidification, due to the low temperature of ...

Abstract

The invention belongs to the refrigeration technical field and particularly relates to an energy-saving refrigeration dehumidifying all-in-one machine. The machine is composed of a compressor, an outdoor condenser, an indoor condenser, a heat regenerator, an evaporator and electronic expansion valves, wherein, the outdoor condenser is connected with the indoor condenser in parallel, and each condenser is corresponding to one electronic expansion valve. When heating up or constant temperature dehumidifying is needed, the indoor condenser and the heat regenerator work. The design of the invention has the functions of refrigeration dehumidifying, heating up or constant temperature dehumidifying, and low-temperature dehumidifying. As the indoor condenser and the heat regenerator are used, the energy consumption is reduced and the dehumidifying capacity is improved. By optimal control, the machine of the invention can adjust the ratio of refrigerants under different working conditions, thus realizing optimal utilization and recovery of energy. The machine of the invention can be used in the fields of a refrigeratory, an artificial climate chamber and the like with the dehumidifying requirement.

Description

technical field [0001] The invention belongs to the refrigerating and dehumidifying machine in the technical field of refrigeration, and in particular relates to an energy-saving integrated refrigerating and dehumidifying machine, which is used in cold storage, artificial climate chamber and other occasions with low temperature or low humidity requirements. Background technique [0002] Freeze dehumidification is the earliest and most common dehumidification method, widely used in machinery manufacturing, optical instruments, electronics, food, chemistry, medicine, facility agriculture and other production fields. Freezing dehumidification is a dehumidification method that uses humid air to be cooled below the dew point temperature to remove condensed water. [0003] Energy saving and environmental protection are the long-term national policies of our country. At present, most refrigeration systems in my country are not equipped with heat recovery devices. A large amount of ...
