Household radiant cooling and heating and fresh air efficient integrated processing device and operating method

Abstract

The invention discloses a high-efficiency integrated treatment device for household radiant heating and cooling and fresh air and an operation method thereof. The device includes a cold / hot water distribution tank, a vapor compression circulation loop, a solution dehumidification / regeneration circulation loop, a frozen water circulation loop, and fresh air dehumidification / humidification module. It has two operating states of cooling mode and heating mode. In the cooling mode, high-temperature chilled water is supplied to the radiant end for radiant cooling. At the same time, the dehumidification solution is used to dehumidify the fresh air after the high-temperature chilled water is cooled, and it undertakes all of the radiant end. wet load. Part of the condensation heat of the air source heat pump unit is used for solution regeneration. In the heating mode, use the same device to generate hot water for radiant heating, and supply humidified fresh air to the room and reduce the risk of frosting on the outdoor evaporator. The present invention can simultaneously realize an integrated air-conditioning unit operating efficiently in summer and winter to drive a radiant cooling / warming air-conditioning system, thereby improving the economy of the air-conditioning system.

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 consideration. [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 ther...

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
