Air conditioner system capable of adjusting temperature and humidity

Abstract

The invention discloses an air conditioner system capable of adjusting temperature and humidity. The air conditioner system comprises a compressor, a gas-liquid separator, condensers, an indoor evaporator and an indoor re-heating coil pipe. The air conditioner system is characterized by furthermore comprising a straight-through valve and a bypass valve, the exhaust end of the compressor is connected with the D end of the straight-through valve and the D end of the bypass valve, the a high-pressure switch and a liquid adding needle valve are arranged between the exhaust end of the compressor and the D ends of the straight-through valve and the bypass valve, the S end of the straight-through valve and the S end of the bypass valve are connected with the air suction end of the compressor, and the gas-liquid separator is arranged between the S ends of the straight-through valve and the bypass valve and the air suction end of the compressor; and a low-pressure switch is furthermore arranged between the gas-liquid separator and the air suction end of the compressor, and the S end of the straight-through valve and the S end of the bypass valve are provided with liquid adding needle valves and capillary tubes correspondingly. The air conditioner system has the advantages that the four-way valves changes application of traditional cooling and heating switching, unreliability of an original electromagnetic valve in system application is improved, an air conditioner unit can be applied to a novel environmentally-friendly refrigerant, and thus the air conditioner system has good development prospect.

Description

Technical field [0001] The invention relates to an air conditioning system with adjustable temperature and humidity. Background technique [0002] The reheat sources after the conventional temperature and humidity air conditioner surface cooler are generally electric heaters, hot water coils, and steam coils. These reheat sources require additional energy consumption, which is consistent with the current energy conservation concept. Contradicts, so will [0003] The heat brought by the surface cooler cooling air to the outside as a heat source is currently a relatively energy-saving method. It is well known that the compressor exhaust is a high-temperature and high-pressure gas state. If it is directly discharged into the reheating coil located after the surface cooler, It will cause the temperature and humidity to be uncontrollable. If a solenoid valve is added to the exhaust pipe to control the flow, the problem of uncontrollable temperature can theoretically be solved, but the ...

Problems solved by technology

[0003] It is currently a more energy-saving method to use the heat brought to the outside by the cooling air of the surface cooler as a heat source. It is well known that the exhaust gas of the compressor is in a high-temperature and high-pressure gas state. If it is directly discharged into the reheat coil located behind the surface cooler, It will cause uncontrollable temperature and humidity. If a solenoid valve is added to the exhaust pipe to control the flow, the problem of uncontrollable temperature can be solved theoretically. However, the structure of the solenoid valve is usually a diaphragm type or a plunger type. It is easy to deform, which will cause the solenoid valve to leak completely, and the pressure loss of the plunger type used at the exhaust end of the compressor will reach 0.6MPa, which will greatly hinder the exhaust of the compressor. When the solenoid valve is closed There will still be a large amount of freon gas leaking into the reheating coil, resulting in relatively large fluctuations in temperature and humidity, which cannot meet customer requirements
