Composite air-conditioning system combining air source heat pump system and rotating wheel dehumidification system

Abstract

The invention relates to a composite air-conditioning system combining an air source heat pump system and a rotating wheel dehumidification system. The composite system comprises a heat pump system and a rotating wheel dehumidification system; the dehumidifier unit consists of a dehumidification rotating wheel, a heat exchange rotating wheel, an evaporator, a heater, an air refreshing machine andan exhaust fan; and the heat pump unit consists of equipment such as a frequency conversion compressor, an outdoor heat exchanger, an indoor heat exchanger, a gas-liquid separator, a four-way change valve and the like. The composite air-conditioning system is combined with indoor radiant heating and cooling, and by means of controlling an electronic expansion valve, an electromagnetic valve, a one-way valve and a constant pressure valve, two vaporization temperature operation conditions are realized; and a dehumidification rotating wheel, a heat exchange rotating wheel, and the outdoor heat exchanger and the indoor heat exchanger of the heat pump unit are combined, the high temperature waste heat of the exhaust air of the compressor is used as the renewable energy for the dehumidificationrotating wheel, and part of cold of the heat pump is used for cooling the refreshed air, thus the performance of the dehumidifier unit is improved.

Description

technical field [0001] The invention relates to a household central air-conditioning cold and hot water system, in particular to a composite air-conditioning system utilizing an air heat source pump combined with a runner dehumidification system. Background technique [0002] Air source heat pumps are widely used in household air conditioning systems to regulate indoor temperature and humidity to meet human thermal comfort requirements. The air source heat pump usually adopts the temperature and humidity joint control technology. The mechanism of this technology is to reduce the air temperature below its dew point, remove the water vapor in it, and turn it into dry and cold air, which is sent indoors to absorb heat and humidity. This technology uses one device and one process to realize two functions at the same time, but it expands the adjustment range of the cooling capacity of the cooling part to be the same as that of the dehumidification, because the reduction of the ev...

[0003] In order to improve indoor thermal comfort and energy saving, many users combine the air source heat pump with the end of the indoor radiant panel, but it is often only used for radiant heating. Due to the problem of condensation on the radiant panel, the application of radiant cooling is limited, so Fan coil terminal unit with low evaporating temperature

[0004] The rotary dehumidification system usually needs high-temperature heat source to regenerate it, such as electric heat, gas and other high-quality energy, and some people use low-quality solar waste heat to regenerate the dehumidification rotor, but the use of solar energy is random, so it needs to be supplemented by other high-quality energy sources. heat source
