A heat pump heat recovery and humidity-controlled fresh air unit and its operation method

Abstract

The present invention relates to a structure and an operation method of a constant-humidity fresh air unit, a heat pump heat recovery constant-humidity fresh air unit. The rectangular unit box (1) is divided into left and right sides or upper and lower sides, with a Intervals and partitions; on the side of the return air passage (A) and exhaust air passage (B), air is supplied from the return air outlet (2) in the room by the return fan (3), and the compressor (4) is connected to the condenser (6) , leading to the air exhaust port (7); on the side of the fresh air channel (C) and the air supply channel (D), from the outdoor fresh air port (8) to the inside, one end of the condensate pump (14) and the condenser on the other side (6) connection, one end is connected to the surface cooler (9), evaporator (10) and second condenser (11) in turn, and the air supply fan (12) is set inward, and the air supply port (13) leads to Indoor; on the clapboard, the air volume automatic regulating valve (5) is set. The invention provides a heat pump heat recovery and humidity balance fresh air unit suitable for temperature and humidity independent control air conditioning system, which has the functions of cooling and dehumidification, heating and humidification, filtering and dust removal, ensuring no condensation on the surface layer of radiation cooling and taking into account health and energy saving.

Description

technical field [0001] The invention relates to a structure and an operation method of a constant-humidity fresh air unit, in particular to a constant-humidity fresh air unit combined with heat pump heat recovery technology and an operation method thereof. technical background [0002] Radiant air-conditioning terminal system is a new form of air-conditioning terminal system invented in the 1970s based on the principle of bionics. The main features of the system are: high comfort, quietness, no condensate pan, no source of bacteria breeding; strong self-adjusting balance ability; no wind feeling, etc., which is conducive to creating a healthy indoor environment. [0003] In the air-conditioning system with independent temperature and humidity control, two independent systems are used to control and adjust the indoor humidity and temperature respectively, thus avoiding the waste of energy and the reduction of air quality caused by the joint treatment of temperature and humidi...

AI Technical Summary

Problems solved by technology

With such a structure, there are low heat recovery efficiency of the heat pump, large energy waste, poor condensed water recovery evaporative cooling effect, poor dehumidification effect, and the system energy efficiency ratio is lower than 7.0
