Energy-saving -type dehumidifying air-conditioning system

Abstract

The invention discloses an energy-saving air-conditioning desiccant system, which comprises a full heat exchanger, a lithium chloride runner and a compression subsystem; the compression subsystem is composed of a low-temperature loop heat pump system and a high-temperature loop heat pump system by serial connection; the outdoor fresh air undergoes the dehumidification after the temperature decrease by the full heat exchanger and then is mixed with the other part of the indoor return air, which is further sent to the interior of a room after the temperature decrease by an evaporator; another outdoor fresh air undergoes the heating by a condenser of the high-temperature loop heat pump system, after that, one line is exhausted to the outdoor atmosphere after the temperature decrease by the evaporator of the high-temperature loop heat pump system; and the other line is taken as a renewable heat source of an absorbent of the lithium chloride runner after the re-heating by the condenser of the high-temperature loop heat pump system. The condensation heat of the low-temperature loop is taken as the heat source of the high-temperature loop heat pump. The condensation heat of the high-temperature loop heat pump is taken as the renewable heat source which is needed by a dehumidification module. The energies of the heat sources and the heat sink can be fully utilized, thus simplifying the structure of the system, simplifying the control and reducing the heat pollution.

Description

technical field [0001] The invention relates to an air conditioner dehumidification device, in particular to an energy-saving air conditioner dehumidification system. Background technique [0002] In summer, the temperature of the cooling water entering the air-conditioned room is generally lower than the dew point temperature of the indoor air, which can easily cause the condensation of indoor water vapor. In order to prevent condensation, the air-conditioned room needs to be dehumidified. Household air conditioners do not have dehumidification devices, relying on cold air for cooling, the indoor is in a state of turbulence, and the indoor is not easy to condense. However, there will be condensed water at the evaporator coil, which is generally led out of the room with a water pipe. There are dehumidification sections in large air conditioning units. Generally, the central air conditioner consists of a fresh air section, a mixing section, a cooling section, a dehumidific...

Problems solved by technology

Although solar energy systems and geothermal systems utilize natural energy, which are more environmentally friendly and energy-saving, the systems are more complicated and the initial investment is relatively large

The operating cost of the gas system is relatively high, therefore, finding a suitable high-temperature heat source is the key technology to achieve solid dehumidification
