Abstract

The invention provides a constant-temperature constant-humidity air conditioner. The constant-temperature constant-humidity air conditioner comprises an indoor unit, an outdoor unit and a control system, and further comprises a compressor, an outdoor heat exchanger forming a condenser of the air conditioner, and an indoor heat exchanger forming an evaporator of the air conditioner, which are sequentially communicated in a circulating mode, wherein an indoor re-heating heat exchanger which is in parallel connected with the outdoor heat exchanger is further arranged between the compressor and the indoor heat exchanger; and the indoor re-heating heat exchanger comprises a micro-channel heat exchanger. The indoor re-heating heat exchanger comprises the micro-channel heat exchanger, is relatively small in inside volume and free of influence on refrigerant circulation quantity while being switched between two modes of the air conditioner due to low occupied refrigerant amount, thereby guaranteeing the energy efficiency and the cooling capacity of the air conditioner. An electronic expansion valve is arranged behind each of the outdoor heat exchanger and the indoor re-heating heat exchanger; by virtue of control of the double electronic expansion valves, heat quantity of the outdoor heat exchanger and the indoor re-heating heat exchanger is intelligently distributed, thereby precisely controlling indoor refrigerating capacity and achieving a purpose of precisely controlling the indoor environment temperature.

Description

technical field

[0001] The invention refers to a constant temperature and humidity air conditioner. Background technique

[0002] High-precision constant temperature and humidity air conditioners have higher precision requirements for temperature and humidity control. The current solution generally uses a refrigeration air conditioner with a large electric heating module and a humidifier. The heating is adjusted steplessly, so that the output cooling capacity can be precisely controlled, so as to balance with the indoor heat exchange, and achieve the purpose of accurately controlling the indoor temperature.

[0003] However, in a laboratory environment without a large heat generation, when the indoor temperature is close to the set temperature, the required cooling capacity output is very small. When the cooling capacity of the compressor remains unchanged, the power of the electric heating should be close to the cooling capacity of the compressor. The electric heater needs...
