Double-medium circulating cooling and heating energy-saving air conditioner

Abstract

The invention belongs to the field of indoor temperature regulation devices and particularly relates to a double-medium circulating cooling and heating energy-saving air conditioner. The double-medium circulating cooling and heating energy-saving air conditioner comprises a unit body, and an air inlet and an air outlet are formed in the unit body. The double-medium circulating cooling and heating energy-saving air conditioner is characterized in that a heat exchange fan, a water circulating system, a refrigerant circulating system and a heat exchanger are installed in the unit body; the heat exchanger comprises a water heat exchange pipe and a refrigerant heat exchange pipe, and the two sets of pipelines are mutually twined and stacked together, but do not communicate with each other; the water circulating system communicates with the water heat exchange pipe of the heat exchanger; and the refrigerant circulating system communicates with the refrigerant heat exchange pipe of the heat exchanger. According to the double-medium circulating cooling and heating energy-saving air conditioner, the advantages of a water air conditioner and a refrigerant circulating air conditioner are combined, the heat exchanger replaces an outdoor unit air cooling heat exchange part of a traditional refrigerant circulating air conditioner, heat exchange is conducted through an underground water source with the relatively-constant temperature, the dry problem of air under normal operation of the refrigerant air conditioner is improved through an independent humidifying system, temperature and humidity control and remote control can be achieved simultaneously, and the design is more humanized.

Description

technical field [0001] The invention belongs to the field of indoor temperature adjustment devices, and in particular relates to a dual-medium circulation heating and cooling energy-saving air conditioner. Background technique [0002] Traditional refrigerant cycle air conditioners and water air conditioners have been widely used in various fields of social production and life. However, due to the limitations of their own structures and working principles, there are advantages and disadvantages in the process of use. [0003] like figure 1 The refrigerant cycle air conditioner shown is divided into two parts: indoor unit A and outdoor unit B. The structure is relatively complicated, and professional personnel are required for installation and maintenance. Part A of the indoor unit of the air conditioner is provided with components such as a capillary tube 1, a check valve 2, a refrigerant evaporator tube 3, and an internal unit heat exchange fan 4. Part B of the outdoor un...

AI Technical Summary

Problems solved by technology

However, due to the limitation of the temperature range of groundwater, the temperature adjustment ability of this air conditioner is also limited to a certain range in terms of heating, which brings inconvenience to use.

[0007] In addition, the evaporator is generally installed inside the machine body, so once it is rusted or damaged after long-term use, it is difficult to find the problem, and it is very inconvenient to check the machine after it is fully opened and other parts removed.

Moreover, if the evaporator is simply placed outside the body, it is easy to cause inconvenience in installation and setting, and the air intake will bypass the evaporator and enter the body without preliminary heat exchange, resulting in a reduction in cooling or heating effect
