技术领域technical field

本发明涉及一种制冷方法及系统，可广泛应用于空气调节领域。The invention relates to a refrigeration method and system, which can be widely used in the field of air conditioning.

背景技术Background technique

对于夏季使用全新风空调，新风中的潜热为空调的主要能耗，常规的空调系统直接冷凝空气，把冷凝水排掉，浪费了大量的能源，当采用干燥除湿方法，又会带来除湿剂再生所需的能耗。如何高效节能的处理新风中的潜热，是解决全新风空调的关键，因此，在基于对水分子在空气中的物理特性研究的基础上，提出全新的地源新风制冷方法及系统。For the use of fresh air air conditioners in summer, the latent heat in the fresh air is the main energy consumption of the air conditioner. The conventional air conditioning system directly condenses the air and drains the condensed water, which wastes a lot of energy. When the dry dehumidification method is used, it will bring dehumidification agent energy required for regeneration. How to efficiently and energy-savingly deal with the latent heat in the fresh air is the key to solving the fresh air air conditioner. Therefore, based on the research on the physical characteristics of water molecules in the air, a new ground-source fresh air refrigeration method and system are proposed.

发明内容Contents of the invention

本发明的目的是提供一种地源新风制冷方法及系统。The purpose of the present invention is to provide a ground source fresh air refrigeration method and system.

本发明的目的是通过下述方法实现的：新风首先通过间接蒸发冷却方法进行预冷至近饱和状态，然后经冷却水高压增湿，使得空气中的水珠体积增大，形成过饱和空气，再利用水幕将空气中的水珠自然沉降及吸附出来，最后通过开放式表冷器，被地源装置总出水的第一出水冷却，形成送风。通过以上方法节省了60％以上全新风空调的能耗。The object of the present invention is achieved by the following method: the fresh air is firstly precooled to a near-saturated state by the indirect evaporative cooling method, and then humidified by cooling water under high pressure, so that the volume of water droplets in the air increases to form supersaturated air, and then Use the water curtain to naturally settle and absorb the water droplets in the air, and finally pass through the open surface cooler and be cooled by the first water outlet of the ground source device to form the air supply. Through the above method, more than 60% of the energy consumption of the new air conditioner is saved.

所述的间接蒸发冷却方法是将自然沉降及吸附的水通过间接的热传递重新蒸发回大自然，并获得被冷却至近饱和状态的新风。The indirect evaporative cooling method is to re-evaporate the naturally deposited and adsorbed water back to nature through indirect heat transfer, and obtain fresh air cooled to a nearly saturated state.

It settles and is absorbed by water, so that a large amount of moisture in the air is reduced to form dehumidified air, and finally passes through the open surface cooler and is cooled by the first outlet water in it to form a supply air.

冷却气体经过间接蒸发冷却器，被加热加湿后，形成排风。被地源装置冷却的总出水分为两路，一路为第一出水，经过开放式表冷器后，形成经过开放式表冷器的出水，再送入水幕，形成经过水幕的出水，另一路为第二出水，经过加湿腔后，形成经过加湿腔的出水，与经过水幕的出水汇合后成为混合水，再经过间接蒸发冷却器，形成总回水。The cooling gas passes through the indirect evaporative cooler and is heated and humidified to form exhaust air. The total outlet water cooled by the ground source device is divided into two paths, one is the first outlet water, after passing through the open surface cooler, it forms the outlet water that passes through the open surface cooler, and then sends it into the water curtain to form the outlet water that passes through the water curtain, and the other way It is the second outlet water. After passing through the humidification chamber, the outlet water that passes through the humidification chamber is formed, and after converging with the outlet water that passes through the water curtain, it becomes mixed water, and then passes through the indirect evaporative cooler to form the total return water.

One section of the multi-section condenser is a channel for mixed water, the other section is a channel for total return water, and the other section is a channel for cooling air. The cooling air first passes through the multi-section condenser to be heated, and then passes through the indirect evaporative cooler to be heated and humidified to form exhaust air. The heat exchange with the heat exchanger is the first outlet water.

所述换热器与其换热的是第一出水和第二出水的总出水，总出水通过换热器后再分为两路。The heat exchange between the heat exchanger and the total effluent of the first effluent and the second effluent, the total effluent passes through the heat exchanger and then is divided into two paths.
