Household radiation cooling, heating and air refreshing efficient integrated processing device and operation method

Abstract

The invention discloses a household radiation cooling, heating and air refreshing efficient integrated processing device and an operation method. The device comprises a cold / hot water distribution box, a steam compressed circulating loop, a solution dehumidification / regeneration circulating loop, a frozen water circulating loop and a fresh air dehumidification / humidification module. The device isprovided with two operating states of a refrigerating mode and a heating mode; in the refrigerating mode, high-temperature frozen water is supplied to a radiation terminal for radiation cooling; and meanwhile, dehumidification solution is used for efficiently dehumidifying fresh air after cooling of the high-temperature frozen water to bear all wet loads of the radiation terminal. Part of condensation heat of an air source heat pump unit is used for regenerating the solution. In the heating mode, the same set of devices is used for generating hot water for radiation heating; and the humidifiedfresh air is supplied indoors to relieve the frosting risk of an outdoor evaporator. The device can synchronously realize that an integrated air conditioning unit operated efficiently under the working conditions in summer and winter drives a radiation cooling / heating air conditioning system, so that the economy of the air conditioning system is improved.

Description

technical field [0001] The invention relates to a cooling and heating and fresh air dehumidification regeneration device and method, in particular to a household type radiant heating and fresh air efficient integrated processing device and an operating method. Background technique [0002] At this stage, the realization of energy-saving air-conditioning system has become the key to reducing building energy consumption. In traditional air-conditioning systems, in order to achieve energy-saving purposes, it is often necessary to sacrifice part of the indoor thermal comfort, and the overall energy-saving and comfort of the system. It is difficult to satisfy both, so it is very important to develop an air-conditioning technology that takes both energy saving and comfort into account. [0003] As a new type of air-conditioning terminal, radiant cooling / heating system has attracted extensive attention due to its remarkable advantages such as low energy consumption, high thermal co...

Problems solved by technology

[0006] 2) The return water temperature of the fresh air dehumidification surface cooler is generally 11-13°C. If it is directly connected to the radiant cooling end, it may cause condensation and affect the indoor thermal comfort. Therefore, it is usually necessary to heat up or directly It is mixed with high-temperature frozen water and then passed into the radiation cooling end, resulting in the loss of cold source grade

[0007] 3) The temperature of the fresh air at the outlet of the fresh air dehumidifier surface cooler may be too low, and directly entering the room will affect the thermal comfort. Generally, it needs to be reheated through a heat exchange device, or the fresh air is mixed with the indoor air by means of induced air supply, and then sent into the room. Indoor, resulting in further loss of cold source grade

In practical applications, the radiant heating air-conditioning system under heating conditions is often independent of the air-conditioning system under cooling conditions. For example, a radiant floor heating system is used in winter and another set is used in summer to avoid condensation problems. The unit is used to drive the traditional split air conditioner, which will lead to a series of problems such as idle unit and low energy efficiency in summer
