Embodiment Construction
[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.
[0019] refer to figure 1 As shown, a refrigerant supercooled reheated air heat recovery system includes a condensing system, an evaporator system, and a heat recovery system. The condensing system, the evaporator system, and the heat recovery system are connected to form a loop. The heat recovery system The system performs supercooling treatment on the refrigerant condensed by the condensing system before entering the evaporator system. The supercooled refrigerant enters the evaporator system for refrigeration cycle. After the evaporator system cools and dehumidifies the fresh air, it heats the fresh air through the heat recovery system. Then carry out air supply.

The invention relates to the technical field of heat recovery of refrigeration air conditioning units, in particular to a refrigerant supercooling and air reheating heat recovery system. The refrigerant supercooling and air reheating heat recovery system is a simple, energy-saving and efficient heat recovery reheating system, a heat recovery system is additionally arranged under the condition thatan original air conditioner connecting mode is not changed, the heat recovery system conducts supercooling treatment on a refrigerant condensed by a condensation system before the refrigerant entersan evaporator system, and the refrigerant subjected to supercooling treatment enters the evaporator system to conduct refrigeration circulation; and the evaporator system cools and dehumidifies freshair, and then the fresh air is supplied after being heated through the heat recovery system, so that a heat source required by reheating of the cooled and dehumidified air can be provided with minimumand simplest investment in a most reliable manner, the supplied air is kept in a constant-temperature and constant-humidity state, and the supercooling degree of the refrigerant before entering an expansion valve is greatly improved, the refrigeration cycle effect is remarkably improved, the COP value of the refrigeration cycle is increased, and the purpose of environment-friendly heat recovery is achieved.
Description
technical field [0001] The invention relates to the technical field of heat recovery of refrigeration and air-conditioning units, and relates to a heat recovery system for reheated air after refrigerant supercooling. Background technique [0002] In many air treatment fields using direct expansion air conditioners, it is necessary to strictly maintain the temperature, humidity and cleanliness of the indoor air for a long time. Therefore, the air treated by the evaporator of the direct expansion air conditioner must balance the heat The load and humidity load are used to achieve a constant temperature and humidity environment. At the same time, the temperature of the air behind the evaporator is much lower than the dew point temperature of the indoor environment. If it is directly sent into the room, it will condense, drip, and mildew on the air supply outlet and indoor walls. , the air treated by the evaporator must be reheated to a temperature higher than the dew point temp...
