Winter and summer dual-purpose heat recycling indirect evaporative cooling air conditioner system with pebble bed heat storage function

Abstract

The invention discloses a winter and summer dual-purpose heat recycling indirect evaporative cooling air conditioner system with a pebble bed heat storage function. The winter and summer dual-purpose heat recycling indirect evaporative cooling air conditioner system comprises a heat recycling-evaporative cooling composite air conditioner set and a pebble bed heat storage unit arranged under the building indoor ground. The heat recycling-evaporative cooling composite air conditioner set communicates with the building interior through an air supply pipe and is further connected with an air return outlet formed in the building indoor ground through an air return pipe and a buried air duct in sequence. The air supply pipe is connected with the pebble bed heat storage unit through a communicating air pipe, and a solar air heat collector is arranged at the joint of the communicating air pipe and the pebble bed heat storage unit. The pebble bed heat storage unit communicates with a floor air supply outlet formed in the building indoor ground. According to the winter and summer dual-purpose heat recycling indirect evaporative cooling air conditioner system with the pebble bed heat storage function, the building indoor temperature can be reasonably adjusted at low energy consumption.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning systems, and in particular relates to a heat recovery indirect evaporative cooling air-conditioning system with a pebble bed for heat storage in both winter and summer. Background technique [0002] According to relevant data, my country's building energy consumption has exceeded 500 million tons of standard coal, of which heating and air conditioning energy consumption accounts for about 50% of building energy consumption, while fresh air energy consumption accounts for more than 30% of the total air conditioning energy consumption. Air conditioning and refrigeration systems in the residential sector consume approximately 15% of the world's total electricity generation. With the rapid increase of urban population, the energy conservation problems of large-scale public buildings and residential buildings built in various regions are particularly prominent, and problems such as energy crisi...

Problems solved by technology

[0003] In the existing HVAC technology, the method of directly processing outdoor fresh air is generally adopted, but it is easy to cause unnecessary waste of resources in long-term use

In fact, the air in the air-conditioned room is cool and dry in summer and warm and humid in winter, which is of great value for use. If it is directly discharged to the outside, it will cause energy waste. If this "free energy" can be effectively recovered and used, combined with Other auxiliary technologies can well solve the problems of high energy consumption and non-energy saving in existing HVAC
