Fresh air temperature control system

Abstract

The invention discloses a fresh air temperature control system, comprising a heating part, an air conditioning part, a fresh air system and a water network. An electromagnetic valve is used to controldirections of a water channel medium, and heat exchange between the water channel medium and fresh air is guided by a water pump and is completed by a gas-water heat exchanger. Indoor temperature isadjusted by a fresh air system. The system has the following advantages: (1) a gas heat exchanger is used, indoor air can be fully exchanged with outdoor fresh air, and indoor cooling and heating loadcan be reduced on the premise of ensuring indoor air quality; (2) compared with floor heating (required water temperature to be 40-50 DEG C) and heating radiators (required water temperature to be 55-65 DEG C), required water temperature of the fresh air system is only 25-35 DEG C, requirements on water temperature is reduced, water storage heat of solar energy can be fully used, at the same time, due to low return water temperature, fuel gas heat can be fully absorbed and nitrogen oxide emission can be reduced; (3) the system has low water storage capacity, can quickly heat up, and is convenient for users to use at any time.

Description

technical field [0001] The invention designs a temperature control system, especially a solar energy, air conditioner, and gas wall-hung boiler combined fresh air temperature control system. Background technique [0002] When cooling or heating is required indoors, the doors and windows usually need to be closed tightly, which makes the room unable to be ventilated and affects the air quality. [0003] Since floor heating or radiators are generally used as heat dissipation equipment for heating at present, there are defects such as large water storage, high outlet water temperature of gas wall-hung boilers, slow temperature rise, and serious heat loss. Contents of the invention [0004] The object of the present invention is to overcome the above defects, to provide a solar energy, air conditioner, and gas wall-hung boiler combined with fresh air temperature control system, which can improve indoor air quality and reduce heating costs. [0005] A kind of fresh air tempera...
