Problems solved by technology

In order to eliminate the residual humidity in the room, it is necessary to provide cold water with a lower temperature. In order to produce low-temperature cold water, the evaporation temperature of the required refrigeration cycle is lower, and the COP of the refrigeration system is lower; In the process of air temperature and humidity treatment, low-temperature cold water exchanges heat with indoor air and wall surfaces through metal tubes and plates, resulting in indirect

Abstract

A dual-temperature radiation household air-conditioner capable of processing fresh air comprises a compressor, wherein an outlet of the compressor is connected with an inlet of a condenser. The outlet pipelines of the condenser are connected with a mental radiation plate and a guiding-type fresh air processor respectively by a first expansion valve and a second expansion valve through a heat regenerator, wherein both inlets of an ejector are respectively connected with the outlet of the mental radiation plate and the outlet of the guiding-type fresh air processor. The outlet pipelines of the ejector are connected with the inlet of the condenser through the heat regenerator. The dual-temperature radiation household air-conditioner is capable of increasing the inlet pressure of the condenser to enable a single condenser to achieve the cooling at two evaporating temperatures, wherein the evaporating temperature of the mental radiation plate which is used as an evaporator is relatively high, thereby being good for improving refrigeration coefficients to achieve the energy-saving effect, avoiding the problem of the secondary heat loss caused by using cold water as refrigerants of radiation air-conditioners, improving indoor air quality and expanding the range of application of air-conditioner systems with independent control of temperature and humidity.

Description

technical field [0001] The invention belongs to the field of HVAC, in particular to a dual-temperature radiation room air conditioner capable of handling fresh air. Background technique [0002] The current use of radiant air conditioners is increasing. For the northern region, the comfort of radiant heating has been more and more recognized by people, and at the same time, radiant cooling has gradually attracted people's attention, especially in my country's first-tier cities, radiant cooling is also developing rapidly. In summer working conditions, the temperature of the refrigerant (usually water) in the familiar radiant plate should not be too low. If the surface temperature of the radiant plate is lower than the dew point temperature of the environment, condensation will easily occur. [0003] Compared with traditional air conditioners, radiant air conditioners have uniform temperature distribution, strong indoor comfort, and low energy consumption. If combined with fr...
