Multi-heat source complementary multi-purpose ice field condensation waste heat cascade utilization system

Abstract

The invention discloses a multi-heat source complementary multi-purpose ice field condensation waste heat cascade utilization system which comprises a refrigerating unit waste heat recovery water tankand a circulating water main pipeline. A compression type heat pump, a main circulating water pump, a fresh air dehumidification system, a heat supply system, an ice field bath system, a terrace anti-freezing system, an ice field ice melting system and a soil heat exchange system are sequentially and circularly arranged on the circulating water main pipeline. According to the system, the soil cross-season heat storage, the solar energy heat supplement and the heat pump technologies are organically combined, so that the complementation of various clean energy sources of the system is realized,various functions of dehumidification, heat supply, bathing, ice melting, terrace freezing prevention and the like are integrated through the optimization of a series flow, a cascade heat supply system with a more adaptive energy level is constructed, and the deep utilization of condensation waste heat and ice melting amount of a unit is realized.

Description

technical field [0001] The invention relates to the field of recovery and utilization of equipment condensation waste heat, in particular to a multi-purpose ice rink condensation waste heat cascade utilization system with complementary multi-heat sources. Background technique [0002] In the process of making ice in the ice rink, the refrigeration unit generates a large amount of condensation waste heat that cannot be fully utilized, and can only be discharged to the outside through the cooling tower, resulting in a huge waste of energy. At the same time, there are various heat demands in the ice rink, such as bathing, ice melting, floor heating, dehumidification, heating, etc., and the heat temperature ranges are different. Among them, the heating area of ​​the venue is large, and the requirements for ensuring the thermal comfort of the venue are also increasing. If we can rationally organize the heating system process according to the principle of "temperature matching an...
