Abstract (en)
[origin: WO2018034846A1] The present invention provides a refrigeration display cabinet, a refrigeration system and a constant temperature control method. The refrigeration display cabinet includes: a refrigeration loop (110), including a compressor (111), a condenser (112), a throttling element (113) and an evaporator (114) which are connected in sequence through pipelines; and a control device (120) communicated with the refrigeration loop and used for directly or indirectly controlling the saturated suction temperature of the refrigeration loop in a preset threshold value range of -2 DEG C to +2 DEG C, wherein the evaporator is a finned heat exchanger, and has a fin density of not less than 6FPI. The refrigeration loop can provide high enough refrigeration capacity for the refrigeration display cabinet and avoid a frosting problem of the fins of the evaporator, thus avoiding a frosting blockage problem of the fins.
