Problems solved by technology

Its characteristic is that it can recycle a certain amount of energy to the fresh air, but the efficiency is low and the price is expensive
In addition: 1. At present, the general small and medium-sized air conditioners fail to automatically switch to the energy-saving operation state when the outdoor temperature is low, and directly use the outdoor low-temperature fresh air to cool the indoor waste heat, wasting a lot of low-cost energy in vain
2. Although the general small and medium-sized air conditioners have dehumidification function, the indoor temperature is also lowered while the indoor unit is dehumidifying. This always makes people feel cold and uncomfortable in seasons with low temperature and high humidity. The method consumes more energy

Embodiment 1

[0026] Embodiment 1: as figure 1 Shown, this fresh wind energy-saving air-conditioning device, its power and connecting device are refrigeration connecting pipe, compressor 1, present embodiment also comprises drying filter 3, throttling device 4, and accumulator 7, electric fan 21, The four-way reversing valve 13 is provided with a fresh air duct 15 and an exhaust air duct 16, an air-cooled heat exchanger 8 is arranged on the new air duct 15, and an air-cooled heat exchanger 9 is also provided on the exhaust air duct 16; . The heat exchanger 8 and the heat exchanger 9 are directly connected with the refrigeration connecting pipe and the compressor 1 to form a refrigeration or heating cycle system. This refrigeration or heating cycle system is used in both the general cooling or heating state, the fresh air ventilation heat recovery state, the energy-saving operation state, or the low-temperature environment dehumidification state. On the fresh air duct 15 there is an indoor...

Embodiment 2

[0031] Embodiment 2: as figure 2 As shown, this example is similar to Embodiment 1, except that dampers 10 and 17 are eliminated, and solenoid valve 5 is added. Therefore, this embodiment does not have the performance of dehumidification without cooling. The added solenoid valve 5 plays the role of changing the flow rate of the throttling device.

Embodiment 3

[0032] Embodiment 3: as image 3 As shown, the power and connecting device of this fresh air energy-saving air-conditioning device are refrigeration connecting pipe, solenoid valve 5 and a package compressor 1, heat exchanger 2, heat exchanger 6, drying filter 3, throttling device 4, The air-conditioning system (heat exchanger 2, heat exchanger 6 can be water-cooled heat exchanger, also can be air-cooled heat exchanger) of liquid reservoir 7, four-way reversing valve 13. In addition, this embodiment also includes an electric fan 21, a throttling device 4, etc., and is provided with a new air duct 15 and an exhaust air duct 16. An air-cooled heat exchanger 8 is provided on the new air duct 15, and a Air-cooled heat exchanger 9; when the solenoid valve 5 is working, the compressor 1 of the air-conditioning system and the heat exchanger 8, heat exchanger 9, and refrigeration connecting pipes form a new air exchange heat recovery state or an energy-saving operating state or a low-...

Abstract

An energy-saving air conditioner supplying fresh air based on existing air conditioner is mainly composed of fan, controller, refrigerating connection tube, and fresh air channel with heat exchanger connected to electromagnetic valve and connection unit connected to existing air conditioner. An exhaust channel with heat exchanger can be also included. Its advantages are exchanging original air with fresh air, recovering heat for saving energy, and dehumidifying effect without lowering indoor temp.

Description

technical field [0001] The invention relates to the field of air conditioning devices, in particular to a fresh air energy-saving air conditioning device. Background technique [0002] In order to meet the requirements of comfort or craftsmanship, modern buildings are generally equipped with air-conditioning equipment, but in order to save energy, most small and medium-sized air-conditioning systems do not have the function of fresh air exchange. People work and live in sealed air-conditioned rooms for a long time, and repeatedly breathe the air polluted by various harmful gases and microorganisms and the oxygen is continuously reduced. They often suffer from so-called air-conditioning diseases such as drowsiness, headache, fatigue, and chest tightness. In order to improve the air quality in air-conditioned spaces: people have adopted various methods, such as multiple filtration, activated carbon adsorption, ultraviolet sterilization, negative oxygen...
