Abstract

The invention discloses an energy and water saving type hot water spraying and defrosting system. The system consists of a refrigerating system, a defrosting system and a control system; the refrigerating system comprises a compressor, an oil separator, an air cooling condenser, a drying filter, a thermal expansion valve, a fin tube evaporator and an air-liquid separator; the defrosting system comprises a water storage tank, a water pump and a spraying device; a water outlet of the water storage tank is connected with a water feeding pipeline provided with the water pump and a first electromagnetic valve in sequence; the spraying device is mounted at the tail end of the water feeding pipeline; and a water collecting disc positioned at the bottom in the fine tube evaporator is connected with a sleeve heat exchanger, a one-way valve, a snakelike coil around the outer side of the oil separator and a water storage tank water inlet through pipelines in sequence. The system needs no additional defrosting heat source and defrosting water; and through efficient utilization of condensation heat and afterheat of the oil separator and recycling of the defrosting water, the energy and water saving purpose of the system can be achieved.

Description

technical field [0001] The invention relates to the fields of low-temperature refrigeration, freezing and refrigeration, and HVAC, and more specifically, relates to an integrated system for utilizing waste heat of a heat pump system and high-efficiency defrosting of an evaporator. Background technique [0002] The evaporator is one of the necessary equipment in the refrigeration system, and its excellent heat transfer performance is related to the operating efficiency of the entire system. The evaporator of the air-conditioning system or the low-temperature refrigeration system operating at low temperature in winter is very prone to frosting, especially in the high-humidity food freezing and refrigeration environment, the frosting of the evaporator is more serious, and the formation of the frost layer increases the heat transfer. The heat transfer performance of the evaporator is significantly reduced due to thermal resistance. Therefore, achieving a frost-free environment f...
