Household heat and humidity separate control radiation air conditioning system and control method thereof

Abstract

The invention provides a household heat and humidity separate control radiation air conditioning system and a control method thereof. Independent temperature adjustment is realized in the process of supplying cold or heat through the radiation of a capillary blanket ceiling plate and floor, and independent humidity control is performed by a novel fresh air treating machine contained in the household heat and humidity separate control radiation air conditioning system. Controllable air pretreatment and tail level temperature readjustment by using radiation water are set, a one-level direct evaporation and two-level series-connected adjustable condensation refrigerating, compressing and dehumidifying system is used, a tail-level condenser also serves as a heat pump evaporator, and an overall machine has an enthalpy reducing function, a dehumidifying function, a variable fresh air ventilating function, a heat recovering function, a heat pump function and the like. The design concept of indoor humidity storage capacity is provided, dehumidification is operated intermittently, and relatively high adaptability for responding to indoor humidity dispersing load variation and relatively high sudden high humidity load bearing capability are achieved. The household heat and humidity separate control radiation air conditioning system is effectively integrated with the cold source and the heat source of a radiation air conditioning system, and has the advantages of high air quality, comfort thermal environment, relatively high energy saving benefit and the like.

Description

technical field [0001] The present invention relates to a new integrated air-conditioning system that combines small and medium-sized traditional household radiant air-conditioning systems with temperature and humidity independent control systems (T&HICS), and relates to a novel multi-functional fresh air processing air-conditioning equipment and household radiant air-conditioning systems. Independent control method of temperature and humidity. technical background [0002] At present, the year-round radiant air-conditioning system using radiant cooling and heating technology relies on its advantages such as comfortable indoor vertical temperature distribution and high system energy efficiency. In recent years, radiant air-conditioning systems have gradually been widely used. At the same time, in order to further explore the advantages of energy-saving integration of the system and create healthy indoor air quality, the radiation system using low-grade high-temperature cold...

Problems solved by technology

At present, as far as the existing humidity adjustment equipment is concerned, the traditional fresh air ventilator can use the low-temperature or high-temperature dry air in the room to complete the residual humidity recovery of the fresh air through the full heat and humidity exchange in the new exhaust room throughout the year, meeting the requirements of the ventilation quality At the same time, it has a certain limited humidity adjustment ability, but it is still difficult to cope with the climate conditions in summer, especially in hot and high humidity areas, and it is impossible to achieve active control and adjustment of humidity; in addition, the fresh air processor of the traditional fresh air DC system has controllable, large Humidity adjustment capability of capacity, but coupled with heat and humidity treatment, the radiant wall panels of the radiation system form redundant settings in the sensible heat elimination treatment, independent control is inconvenient, and the existing low-grade high-temperature cold water (15-20°C) cannot be used ) or low-temperature hot water (30-40°C), it is necessary to use a dual-temperature cold and heat source unit, the system is huge, and the overall energy-saving advantage is reduced; while the solution independent dehumidification equipment can be better transplanted into the radiant air conditioning system, but the complexity of the equipment is not conducive to Small and medium-sized household systems, and the manufacturing and maintenance costs are relatively high
