Embodiment 1

[0035] Such as figure 1As shown, this embodiment provides a dual heat recovery capillary radiation system, the dual heat recovery capillary radiation system includes an accommodation space 100, a total heat exchanger 3, a fresh air fan 4, a sensible heat exchanger 7 and an exhaust fan 9, the The accommodating space 100 includes an exhaust air outlet area 101, a fresh air inlet area 102, an exhaust air delivery area 103, a fresh air delivery area 104, an indoor return air area 105, and a fresh air supply area 106. The exhaust air outlet area 101 is provided with exhaust The air outlet 107, the fresh air inlet area 102 is provided with a fresh air inlet 108, the indoor air return area 105 is provided with an indoor return air outlet 109, the fresh air supply area 106 is provided with a fresh air outlet 110, and the exhaust fan 9 is set in the exhaust air conveying area 103, the fresh air blower 4 is set in the fresh air conveying area 104, and the total heat exchanger 3 has a fi...

Embodiment 2

[0038] Such as figure 1 As shown, the dual heat recovery capillary radiation system also includes a fresh air primary effect filter 1, and the fresh air primary effect filter 1 is arranged in the fresh air inlet area 102, and the fresh air inlet 108 passes through the fresh air primary effect filter. The net 1 communicates with the second inlet of the total heat exchanger 3 . In this embodiment, the fresh air is filtered through the fresh air primary effect filter 1, which reduces the particulate matter content in the fresh air.

Embodiment 3

[0040] Such as figure 1 As shown, the dual heat recovery capillary radiation system also includes a fresh air high-efficiency filter 2, the fresh air high-efficiency filter 2 is arranged in the fresh air inlet area 102, and the fresh air inlet 108 passes through the fresh air primary filter in turn 1 and the fresh air high-efficiency filter screen 2 communicate with the second inlet of the total heat exchanger 3 . In this embodiment, the fresh air is filtered through the fresh air high-efficiency filter 2, which reduces the particulate matter content in the fresh air.

Abstract

The invention discloses a double-heat-recovery capillary tube radiation system. According to the double-heat-recovery capillary tube radiation system, on the basis of a single-water-cooling fresh airdehumidification unit, a front total heat exchanger, a rear sensible heat exchanger and a rear wet film humidifier are additionally arranged, a surface air cooler is redesigned, and the heat exchangecapacity of the surface air cooler is improved; the front total heat exchanger is used for pre-cooling and dehumidifying fresh air, and then the surface air cooler is used for carrying out secondary cooling and dehumidifying on the fresh air; in this way, even under the working condition of high dehumidification load, the humidity of the treated fresh air can meet the requirement needed by a radiation air conditioning system; the rear sensible heat exchanger can be in a water and air heat exchange coil pipe form and can also be in an air and air heat exchange fin plate sheet form; the rear sensible heat exchanger is used for reheating the fresh air, the air supply temperature is increased, and the requirement for the air supply comfort degree is met; and meanwhile, due to the fact that a compressor direct expansion refrigeration system is not arranged, the size of equipment does not need to be increased.

Description

technical field [0001] The invention relates to the field of HVAC technology, in particular to a dual heat recovery capillary radiation system. Background technique [0002] The household fresh air processing unit required for the application of capillary radiant air conditioning mainly has the following methods at present. The first method is to use single water cooling to cool and dehumidify. to request. [0003] The second method is to use the front-end heat recovery and the rear-end compressor direct expansion system to dehumidify. In order to reduce the volume of the equipment, the compressor system configured is generally small, and the dehumidification capacity is also insufficient under high-load dehumidification conditions. , the humidity after the fresh air treatment does not meet the requirements. At the same time, because the equipment includes a compressor refrigeration system, the failure rate of the fresh air dehumidification unit will increase a lot, and for...
