Capillary tube radiation double-cold-source total-heat fresh air dehumidification air conditioner all-in-one machine unit

Abstract

The invention provides a capillary tube radiation double-cold-source total-heat fresh air dehumidification air conditioner all-in-one machine unit, which comprises a shell, and a fresh air opening, anair return opening I, an air return opening II, an air supply opening, an air exhaust opening and a cold and hot water inlet and outlet opening are arranged on the shell; wherein a heat exchange system and a refrigerating and dehumidifying system which are matched with each other are arranged in the shell, and the heat exchange system comprises an air feeder, a medium-efficiency filter screen, aheat recovery core body, an air return valve, an exhaust fan, a primary-efficiency filter screen, a fresh air valve and a fresh air valve which are matched with each other; the air feeder is arrangedat the front part of the shell; the refrigerating and dehumidifying system adopts double-cold-source refrigeration and comprises a compressor, an evaporator, a surface air cooler, a regenerative condenser, a heat dissipation condenser, a two-way electric control valve, an electronic expansion valve A, an electronic expansion valve B, a one-way valve, a filter C, a filter D, a capillary tube, a pressure sensor and an electromagnetic valve which are matched with one another; the refrigerating system adopts double-cold-source refrigeration, a first-stage pre-cooling dehumidification function is added, the dehumidification effect is more obvious, and more energy is saved; and the problem that negative pressure drainage is difficult after a fan is arranged is solved, and the structure is more reasonable.

Description

Technical field: [0001] The invention belongs to the field of fresh air air conditioners, and relates to a capillary radiation double cold source all-in-one fresh air dehumidification air conditioner unit. Background technique: [0002] The unidirectional flow fresh air dehumidification unit of prior art is as Figure 8 and Figure 9 shown. The original unidirectional flow fresh air dehumidification unit has no heat exchange function, only dehumidification function. [0003] ventilation system such as Figure 8 Shown: Principle: Dehumidification mode: When the ambient humidity sensor detects that the ambient humidity is too high, the blower is turned on, and the compressor is turned on; the indoor return air (humid air) and outdoor fresh air are filtered and purified by the primary filter and the high-efficiency filter before being sent to the blower Send it into the room to achieve the desired effect in the room. When the ambient humidity probe detects that the ambient h...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the defects existing in the prior art, the present invention provides a capillary radiation double-cooling source full-heat fresh air dehumidification air conditioning unit, which combines the functions of the original heat exchange fresh air unit and the original unidirectional flow fresh air dehumidification unit. It has the heat exchange function of fresh air and exhaust air, and also has the functions of dehumidification, cooling, and heating. It is a multi-functional all-in-one machine; it has an additional level of pre-cooling and dehumidification function, the dehumidification effect is more obvious, more energy-saving, and improves people's quality of life; And it solves the problem of difficult drainage of negative pressure after the fan, and the structure is more reasonable
