Total-heat fresh air exchange equipment with isothermal or temperature-rise dehumidification function

Abstract

The invention discloses total-heat fresh air exchange equipment with an isothermal or temperature-rise dehumidification function. The total-heat fresh air exchange equipment comprises an outdoor unitand an indoor unit which are connected by a copper pipe, and is characterized in that the outdoor unit is internally provided a compressor, a four-way valve, an outdoor fan, an outdoor condenser and an outdoor electronic expansion valve, the indoor unit is internally provided with a reheat condenser, an indoor evaporator, an indoor fan, a one-way valve, a dehumidification throttling device, a solenoid valve, a stop valve, an exhaust fan, a total-heat exchange core, an air filter net and a controller, an exhaust air outlet, a fresh air inlet and fresh air outlets are formed in cases on the leftside and the right side of the indoor unit correspondingly, and an exhaust air inlet and a circulating air inlet are formed in a case on the front side of the indoor unit. The temperature of a refrigerant outlet of the outdoor condenser is controlled by the controller to control the heat dissipation ratio of the outdoor condenser and the indoor reheat condenser, so that the temperature of indooroutlet air is controlled to be higher than or equal to the temperature of return air, an isothermal or temperature-rise effect is achieved, and a living environment with the suitable temperature and humidity is provided.

Description

technical field [0001] The invention relates to a full-heat fresh air exchange device with isothermal or temperature-raising dehumidification function, which belongs to indoor air quality adjustment equipment. Background technique [0002] With the continuous improvement of people's living standards, people pay more and more attention to the quality of indoor environment, and maintaining good indoor air plays an important role in personal health. At present, the equipment for adjusting indoor air is mainly air conditioners and fresh air exchangers. The main function of fresh air exchangers is to adjust the air conditions in people's lives and workplaces, and make full use of the old air that needs to be replaced. The energy (heat energy or cold energy) in the system can reduce energy consumption as much as possible while exchanging air, so as to achieve the purpose of energy saving and environmental protection. Traditional air-conditioning dehumidification is to cool the ai...

Problems solved by technology

Traditional air-conditioning dehumidification is to cool the air through the air-conditioning evaporator to condense the moisture in the air, but the room temperature will also drop during dehumidification, which belongs to cooling dehumidification. The temperature and humidity indicators can only meet one, and the comfort is not high. It is more and more necessary to keep the temperature and humidity within a reasonable range, especially for coastal areas. During the transitional season, the humidity is high and the temperature is relatively comfortable, so isothermal dehumidification equipment is particularly necessary
