Novel dual-cold-source fresh air ventilator and air conditioning system

Abstract

The invention discloses a novel dual-cold-source fresh air ventilator and an air conditioning system. The novel dual-cold-source fresh air ventilator comprises an outdoor air supply passage of fresh air, a side passage, a first sub-cold-source system and a second sub-cold-source system; the side passage is installed besides the air supply passage; a first heat exchanger, a second heat exchanger and a third heat exchanger are successively arranged in the air flow direction at the air supply passage; a fourth heat exchanger is installed at the side passage; the first heat exchanger and the fourth heat exchanger are connected in parallel to fluidly connect with the first sub-cold-source system; the sub-cold-source system is fluidly connected with the second heat exchanger, the third heat exchanger and the fourth heat exchanger. The invention not only improves indoor comfort, but also saves energy, has good practicability, applicability, good market prospects and market competitiveness, and is in line with China's national policies such as energy saving, environmental protection and green building, and is in line with China's national conditions.

Description

technical field [0001] The invention relates to the technical field of air conditioning and energy utilization, in particular to a novel dual cold source fresh air fan and an air conditioning system. Background technique [0002] In recent years, the economy has developed rapidly, and the number of high-end apartments and office buildings in major cities has increased dramatically, resulting in increasingly tight energy supply. Among them, the energy consumption of air-conditioning accounts for more than half of the energy consumption of the entire building, and the current air-conditioning system is mainly driven by electricity, which has caused a shortage of urban power supply. Therefore, it has become an urgent matter to adopt all feasible schemes to reduce building energy consumption and alleviate the power shortage. Building low-energy buildings and using energy-saving green air-conditioning systems are among the most effective solutions. [0003] Radiation cooling (w...

Problems solved by technology

However, since the radiant cooling (warming) system can only solve the indoor sensible heat load, but cannot solve the indoor latent heat load, the indoor is prone to condensation, which not only affects the indoor environment, but also limits the cooling capacity of the system due to the limitation of the dew point temperature. , but also reduces the comfort of people
